Preface. Welcome to the SIG ‘2x2 OpEx’ portal! “The SIG 2x2 OpEx addresses one of the key challenges of the Dutch Process Industry in the years ahead. Managing an aging asset base in a safe and economic way will be crucial for a sustainable future. I trust that NAP participants will be inspired and will benefit from the ideas and best practices generated by this group.” Robert Claasen, chairman NAP “Reducing operational expenditures while extending the life cycle of our production facilities, is key for the competitiveness and continuity of our Dutch Process Industry. I'm very proud that expert colleagues from across our industry collaborated to address this challenge together.” Koen Bogers, chairman Production Assets team, NAP. In the spring of 2012 the SIG ‘2x2 OpEx’ was formed to conduct a survey to identify ways to “extract more from our aging assets as much reduced opex through the NAP value chain”. A more detailed description can be found in the ‘SIG 2x2 OpEx Charter – NAP Production Assets’ (Feb. 2012). The Process Industry Competence network NAP is pleased to present the results of this survey. Approach As a mindset the ambition was to identify ways to bring down operational costs by a factor 2 while at the same time extending an asset’s life time by a factor 2. The special interest group focused on: Interventions on interfaces in the value chain, impacting execution excellence op operations and maintenance (both effectiveness and efficiency) Identifying ‘low hanging fruits’, i.e. best practices that can easily be implementend as a quick win Identifying best practices (also from outside the process industry) © Stichting NAP, Nijkerk 5 Reviewing the human factor Providing examples of tools to support implementations During initial brainstorm workshops ‘low hanging fruit’ and a number of topics were identified; all these topics were clustered into 6 themes, some of them generic, i.e. applicable across all themes. For each theme a ‘twinning’ (group of 2) was formed. In practice however we found that the number of themes should be brought back to 3 and also that working in groups of 2 persons slows down the process (if one person is unavailable the other can or will not proceed either). Introducing working sessions and expanding the twinning teams (4-5 persons per theme) helped boosting the process. A number of meetings were held at various SIG-member locations. The final 3 major themes the SIG has been focusing on are: 1. Continuous improvement processes and performance management 2. Asset and maintenance management 3. Turnaround management The SIG is well aware that these topics partly overlap and also interact with each other. Therefore, the findings of the SIG regarding a specific topic should be placed in the broader context of all 3 themes together. You are invited to explore our findings, learn from them, apply them in your situation and share them with your peers. Pier-Jan Hettema Chairman of the Special Interest Group ‘2x2 OpEx’ Results Centered around each theme, this portal provides you with theoretical background and literature surveys (captured under ‘models and methods’) as well as best practices, business cases with experiences from the Industry itself and input of the SIG-members themselves, based on their many years of working experience. © Stichting NAP, Nijkerk 6 The SIG has been able to identify both theoretical context for the industry to further optimize on opex, and has brought together a number of best practices with (indications of) quantified realized benefits. Conclusions Realizing 2x2 OpEx is about running a marathon, not sprinting the 100 m. It is all about longterm vision on optimizing assets and productivity, integrated approach (CI, maintenance, turnaround mgt etc.) and investing at the right moment. We need Gebreselassi, not Bolt. Another key success factor is the ability to choose a method and stick to it, from top management to the work floor. The SIG trusts that the content brought together in this portal will be inspiring for you to start identifying ‘2x2 OpEx’ opportunities yourself. We are well aware that ‘2x2 OpEx’ should not be limited to these 3 themes alone. Therefore, you are kindly invited to share your experiences, comments, additions and other feedback with the SIG community, in order to continously improve on the contents of this portal.

General introduction. The NAP Special Interest Group ‘2x2 OpEx’ has set itself the following objectives: “Reduce operating expenditures significantly -by double-digit percentages- and extend the remaining economic life of aging assets by a factor of 2 through the NAP value chain by sharing best practices, knowledge, tools et cetera. Develop improved approaches to operational and maintenance practices”. In the process industry operating expenditures in manufacturing can be reduced in many ways. Prominent among these are programmes and methods collectively labelled continuous improvement (CI): the systematic, continual and incremental improvement of plant operating efficiency and performance in each and every respect, daily, weekly, monthly. This stream of the SIG 2x2 OpEx is aimed at providing practical guidance to members of NAP on the methodologies they may adopt to continuously improve their manufacturing operations and achieve operational excellence in line with the above ‘2x2’ targets. Focus. This study focuses on: - existing manufacturing facilities in the process industries, with - plants that basically employ state-of-the-art technology and - operate internationally in relatively stable product-markets. Situations are considered in which drastic measures are not directly needed, but where the life-cycle return on the productive assets can and indeed must be improved incrementally and continually to stay ahead of the competition. To this end, a vast range of techniques have been proposed, but in the present discussion emphasizes will be placed on methods that have been tried and tested in actual practice. In this respect, the programs developed and introduced successfully by AkzoNobel Industrial Chemicals and Royal FrieslandCampina, respectively, will be discussed extensively. Keeping track of progress is a key element in continuous improvement. Hence, special attention is given to measuring and managing performance by the use of Key Performance Indicators. © Stichting NAP, Nijkerk 10 Definitions. CI and innovation Continuous Improvement and innovation differ essentially. The latter entails revolutionary, breakthrough technology/concepts/materials or totally novel equipment or plant designs that have never been used before. Innovation is pioneering and basically technology-driven, whereas continuous improvement aims at operational excellence in existing installations. Improvement occurs in small steps. Solving a problem each day, making sure that in the evening the organisation performs a little better than in the morning. That is not to say that the use of innovative materials of construction, advanced pumps or smarter process controls and sophisticated software would not fit into a Continuous Improvement Programme. Operating expenditures OPEX (Operating Expenditures) comprise both direct and indirect production costs. The former include variable costs like raw materials, utilities, consumables and waste removal, and fixed costs like operating labour, supervision/clerical and maintenance & repairs. Indirect costs include plant overhead and general expenses. Hence, Continuous Improvement concerns a vast area of items from leaking steam traps to analysing product quality, from outsourcing maintenance to sourcing of raw materials. Remaining Economic Life (REL) Continuous Improvement in Production (CIP) undoubtedly contributes to achieving the target of extending economic life in a qualitative sense. But lengthening the economic life is seldom the prime objective or the starting point of CIP. Better maintenance or more prudent operation and house keeping will both increase the technical life of plant and equipment. But technical life does not directly reflect economic life and is normally very much higher than economic life. In general, the Remaining Economic Life is influenced by an array of factors like diseconomies of scale, technological obsolescence, competitive environment, industry cost curve (i.e. relative product cost split-up among competitors) or product substitution. Some of these factors can be influenced by the company and others cannot, but most factors are beyond the scope of continuous improvement programmes. Achieving the above SIG OpEx target means determining the current REL versus the REL resulting from putting in place an improvement programme. There are a great many definitions for the REL, one of the simplest being: "the time after which we save money by replacing the asset". To calculate this parameter, we enter the world of finance & accounting: replacement analysis, abandonment value forecasting, equivalent uniform annual cost of the asset over its life. This is beyond the scope of the present paper. Acordio has however studied the subject separately and developed a new model (based on Discounted Cash Flow Analysis) to simply calculate economic life and the effects of OPEX © Stichting NAP, Nijkerk 11 reduction. In the present contribution economic life target has been interpreted as being reflected by for example halving losses, doubling time intervals between scheduled maintenance stops and unscheduled failures, halving time for maintenance & repairs.

The European manufacturing industry is facing great challenges nowadays: a decreasing local demand, wages and energy costs are high and global competition is fierce. In particular in traditional industries with little potential for innovation and aging assets, management of operating expenditures (OPEX) is key to the continued survival of a plant. One way to do this is to adopt a continuous improvement strategy, consistently aiming at best-in-class performance throughout the organisation over time. Many companies have introduced a variety of Continuous Improvement (CI) systems more or less successfully in the past decade. The state of the art has been reviewed to help members of NAP with the development of their own Continuous Improvement system. Implementing CIP should not be taken lightly. A number of pre-conditions for success and lessons learned have been identified: Strong and enduring (top) management commitment Perseverance: comprehensive results come after years not months. Empowerment and buy-in & ownership of personnel at all levels Continued availability of resources, both human and financial Formal procedures not stifling the organisation in meetings and paperwork Training at various levels CIP is a powerful tool for Operational Excellence and OPEX reduction Payback times of less than one year are frequently achieved in CIP. Performance Management is of importance in any organisation, but in CIP it is indispensible. Performance Management has been shown to include: Selection of a sufficient number of parameters that are really key to the organisations performance. These Key Performance Indicators (KPIs) should be uniquely defined and measurement should be relatively simple. Setting targets for each KPI over time. Determine what factors and mechanisms influence KPI values. Recording actual KPIs consistently and comparing actual and target values Introduce measures to remedy variances © Stichting NAP, Nijkerk 14 In most cases performance is to be monitored at different levels: more basic performance indicators are derived from the main KPIs to form a “KPI tree” involving employees down to the shop floor. Modern industrial automation systems can make a significant contribution to continuous improvement processes. An illustrative overview has been given from the perspective of Siemens. It has for instance been shown how Energy Management Systems, Statistical Process Control and Process Simulation Systems can efficiently provide input for CIP. Also, automatically determining the important KPI of Overall Equipment Effectiveness (OEE) online , real time offers great advantages. Enduring success of CIP on the mid and long term has been shown to depend very much on short term results. Such quick wins are necessary to bolster acceptance at the beginning of the CIP program and motivate people to put in the required effort. A range of tried & tested quick wins has been delineated. Lastly, taking the perspective of the NAP Network, it is of interest to note that most CIP systems fail to directly address the issue of improving the organization together with its client and supplier partners. It is recommended that NAP takes the initiative to fill this gap. Quality management. Quality management in an organisation deals with assuring and improving the quality of a product, production process, service or organisation in a systematic way. Trade and industry, as well as non-profit organisations are increasingly confronted with ever more demanding clients and improved products of competitors. Nowadays, our society asks for more sustainable products and processes, while emerging countries like China or India are considered as a threat. Next to that, the government demands more and more with respect to the quality of the supplied goods and services, as well as of the organisation itself. Therefore organisations are forced to continuously improve the quality and to assure it. Thus organisations must guide themselves in improving their quality. These reasons make quality management an essential means to achieve a sustainable organisation. Goals The goals of quality management are: improving customer satisfaction (internal as well as external clients) assuring and continuously improving the quality of products and services assuring and continuously improving the general operation of the business increasing the effectiveness and efficiency decreasing the number of mistakes reducing the costs © Stichting NAP, Nijkerk 15 mastering and lowering the risks There are many ways and approaches to achieve the desired result. The ones to choose depend on the organisation to be considered. Like other management issues, quality management has a number of pitfalls. The most elementary are: management is focused on norms in stead of on improvement insufficient support in the organisation insufficient guidance for the process of quality management insufficient enduring management commitment Notes: 1) the management improves the system and stimulates/assures an enduring open communication and appraisal culture, which is appreciated by everyone. 2) In practice Total Quality Management (TQM) methods were introduced, but many organisations did not succeed in holding the improvement culture over a long time: the organisations fell back in the old pattern of accepting that the existing situation is good enough and that mistakes are normal. After the improvement project, the situation falls back and an increasing number of mistakes is accepted. History The roots of modern continuous improvement programs can be traced back to initiatives around World War II. The US government set up the “Training Within Industry” service during the Second World War to enhance industrial output on a national scale. This included job method training, a program designed to educate supervisors on the importance and techniques of CI methods. This program was later introduced in Japan by management experts like Deming, Juran, and Gilbreth, and by the US forces present there after the end of the Second World War (Robinson, 1990). Eventually, the Japanese developed their own ideas and quality control evolved into a management tool for ongoing improvement involving everyone in an organization (Imai, 1986). While CI initiatives in the past reflected the use of various principles related to work improvement, today CI is associated with organised and comprehensive methodologies. These CI programs, in which typically the whole organization is involved, are also more popularly associated with the introduction of the TQM movement, which also gained leverage in Japan thanks to Edward Deming in the fifties and later also in America and Europe. Over the decades, as the need to continuously improve on a larger scale became an imperative, a number of CI methodologies were developed based on a basic concept of quality or process improvement, or both, in order to reduce waste, simplify the production © Stichting NAP, Nijkerk 16 line and improve quality. The best known of them are: statistical process control, zero defects, lean manufacturing, six sigma, the balanced scorecard, and lean six sigma. In the second half of last century Juran, Deming and Crosby have shown that costs are decreasing at increasing quality. Models and methods. The three main types of processes in organisations are ‘governing’, ‘steering’ and ‘implementing’. These types will be introduced further: Governing: “directing” the organisation: The long term ideas are fixed in the mission and vision statements. These declarations are the starting and leading point for a number of questions. What products are we going to deliver in the coming 3 to 5 years, to what clients and in what markets? How do we have to adapt the organisational structure and culture of our organisation? Steering: “organizing”: A continuous improvement methodology is chosen to answer the above questions. The improvement method brings structure in the organisation. The required resources are made available: training, time and money. Implementing: “performing”: The executing of the parts of the improvement program. A number of well-known models and methods, sorted after the above processes, is described in the following subsections. Governing INK model (2003) The “ Instituut Nederlandse Kwaliteit (INK)” is the Dutch partner organisation of the EFQM (European Foundation of Quality Management) Representative Office in Brussels. INK is mainly known by their management model: the INK-model. The INK-model (based on the EFQM-model) is a broadly used management model and is intended to carry out a self assessment. By means of the INK-model, the maturity of the organisation is being determined and improvement points identified. The model helps organisations to focus on improvement areas in their management structure. ISO 9001 (2008) ISO 9001 is an international standard of a quality management system, describing the minimum requirements for the way an organisation functions, for working procedures and © Stichting NAP, Nijkerk 17 the way of satisfying customer’s expectations. These requirements are set to the following areas: Plan and Manage Business, Supply Chain, Marketing and Sales, Produce and Maintain, Manage Risks, Innovate, Audit and Review, Manage Personnel, Correct, Prevent and Improve, Document Control and Know Mandatory Requirements. Steering Balanced Score Card The business Balanced Score Card (BSC) is a model to define the organisational goals and a help to steer toward these goals. The key performance indicators (KPIs) or critical success factors (CSFs) become logical. This allows the BSC to function as a means to direct the organisation. Performances of organisational sub-units can be monitored. Six Sigma Six Sigma (striving for effectiveness) initiatives are based on a pre-planned project charter that outlines the scale of a project, financial targets, anticipated benefits and milestones. Six Sigma is based on DMAIC (Define-Measure-Analyze-Improve-Control) that helps in making precise measurements, identifying exact problems and providing solutions that can be measured. Lean manufacturing Lean Manufacturing (striving for efficiency) focuses around shortening the production cycletime, resulting in an enhancement of the productivity, without losing quality or rising costs. Lean Six Sigma Lean Six Sigma is a world-wide proven and applied method, which brings recognizable and sustainable improvements of business results. The method focuses on those items the customer really cares for. This approach brings in parallel cost reductions , improvements of customer satisfaction, and reductions of the cycle-times. Total Quality Management Total Quality Management (TQM) is an integrated management philosophy for continuously improving the quality of products and processes. TQM works on the premise that the quality of products and processes is the responsibility of everyone who is involved in the creation or consumption of the products or services offered by an organization. In other words, TQM requires the involvement of management, workforce, suppliers and customers, in order to meet or exceed customer expectations. Considering the practices of TQM as discussed in six empirical studies, Cua, McKone and © Stichting NAP, Nijkerk 18 Schroeder (2001) identified the nine common TQM practices as: 1) Cross-functional product design 2) Process management 3) Supplier quality management 4) Customer involvement 5) Information and feedback 6) Committed leadership 7) Strategic planning 8) Cross-functional training 9) Employee involvement Theory of Constraints In Theory of Constraints (ToC) improvement of the cycle time has the highest priority. By exploiting and/or removing constraints in the logistic chain, the efficiency of the production chain as a whole is improved. ToC is developed by Dr Eliyahu Goldratt. Thus searching for, exploiting and/or removing the bottleneck in a process is the golden rule of ToC resulting in a shortening of the cycle time. One hour shortening of the cycle time of the bottleneck machine means a one hour cycle time gain in the whole production line. Comparable with Lean, the optimal logistic processes are the drivers. ToC is more internally focused than Lean: what causes the constraints in the process and how can it be solved. However, the latest addition of Goldratt was the search for business opportunities (hidden constraints) by systematically mapping causes, results and opportunities. Total Productive Maintenance In the course of the years the attention area of Total Productive Maintenance (TPM) became broader. Next to maintenance also product loss, productivity improvement and reduction of the costs of mistakes became attention areas for improvement. TPM has grown to a widely accepted system of business management in order to realize operational goals for the short and long term. Therefore the term Total Production Management (TPM) covers the aim of the method better. Implementing Statistical Process Control Statistical process control (SPC) is a method of quality control which uses statistical methods. SPC is applied in order to monitor and control a process. Monitoring and controlling the process ensures that it operates at its full potential. At its full potential, the process can make as much product conforming to specifications as possible with a minimum (if not an © Stichting NAP, Nijkerk 19 elimination) of waste (rework or trash). SPC can be applied to any process where the "conforming product" (product meeting specifications) output can be measured. Key tools used in SPC include control charts, a focus on continuous improvement and the design of experiments. Kaizen Kaizen (改善), Japanese for "improvement" or "change for the better" refers to philosophies or practices that focus on continuous improvement of processes in manufacturing, engineering and business management. It has been applied in healthcare, psychotherapy, life-coaching, government, banking and other industries. When used in the business sense and applied to the workplace, kaizen refers to activities that continually improve all functions and involves all employees from the CEO to the assembly line workers. It also applies to processes such as purchasing and logistics that cross organizational boundaries into the supply chain. By improving standardized activities and processes, kaizen aims to eliminate waste (see lean manufacturing). Kaizen was first implemented in several Japanese businesses after the Second World War, influenced in part by American business and quality management teachers who visited the country. It has since spread throughout the world and is now being implemented in many other venues besides just business and productivity. 5S 5S has been developed in Lean Manufacturing to improve the efficiency at the shop floor. It consists of the following consecutive repeating steps: S1 Separate (Seiri): S2 Sort (Seiton): S3 Shine (Seiso): S4 Systemize (Seiketsu): S5 Standardize (Shitsuke): separate essentials and superfluities sort in a logical way what rests after Seiri keep machines and working area clean repeat step 1 through 3 and act as required this way of living is the new norm. Application and experiences In the process industries L6Sigma and TPM are frequently used with excellent results. However, generally their usage lasts only a short period of time and the organisations fall back in their old habits and behaviour. Two business cases, AkzoNobel Industrial Chemicals and Royal FrieslandCampina, describe how these companies successfully introduced L6S and TPM, respectively. © Stichting NAP, Nijkerk 20 Performance management. “However beautiful the strategy, you should occasionally look at the results” Sir Winston Churchill, British politician (1874 - 1965) Introduction to Performance management Performance management is a very important management tool and a ´must have´ for every organization that strives for operational excellence and continuous improvement. Performance is expressed in Key Performance Indicator (KPI) values. We compare actual values with target values and measure how successful we are. KPI values are the ultimate performance indicators. This doesn’t mean that they are the only or even the most important part of performance management. Vital for performance management is the translation of the gap between current and targeted values into (sources of) losses, combined with the contribution of every individual employee in the “closing the gaps” and “holding the gains” processes. How this is done is explained in the contribution of FrieslandCampina . Operational Excellence will never be achieved if it is considered and treated as a management responsibility solely. We see many examples of good improvement activities with excellent results that fade away over time and are not sustainable. The reason is that the organization is not capable to hold the gains. The management is confused and uncertain: why do we see a more or less flat KPI trend, while at the same time launching many successful improvement activities? There is a general answer to that question: in all cases we see a poor performance control system. High performance production organizations distinguish themselves by a low number of unplanned stops as expressed by a high Overall Equipment Effectiveness (OEE) number. There are hardly any short stops, breakdowns or supply failures. The organization is in control. The high performance organization is capable of keeping losses under control. It learned that losses can be caused at every operational level, from the shop floor to (top) management. Therefore every single employee has a role in reducing losses that are above the target values. It is also important that performance control is both a top down and bottom up process. Management selects the KPIs and defines the target values. These KPIs are indeed the keys to success for the organization. The target values are the goals to achieve in the operational excellence journey. In general the organization has KPIs in the fields Productivity, Quality, Costs, Delivery, Safety Health & Environment (SHE) and Environment & Motivation. The improving organization analyses the losses/variances and executes improvement activities. In this top down process both the management and the improvement organization must communicate about the reasons why and the importance of the choices. Only then the people on the shop floor can understand why it is so important and will be willing to make © Stichting NAP, Nijkerk 21 the efforts and support the program. Holding the gains is mainly a bottom up process. Losses are not found at KPI level but in the underlying sources of losses. Let’s have another look at the OEE example. No organization can be in control by only looking at the KPI level. You need to control the underlying sources of losses. The short stops, breakdowns or supply failures mentioned above are generated on machine level at the shop floor. So you can only control them at shop floor level. Primary responsible for this should be the operator or the technician. Every employee has a role in the performance control process. Identification of the sources of losses and being in control on shop floor level is of course applicable in both continuous and batch processes. Two last remarks on this topic: 1) Make very clear what the responsibility is per person or function. There must be no misunderstanding about the question who executes a specific task. 2) Make sure there is an ‘escalation’ procedure. This procedure states after what period of time or degree of seriousness the problem should be escalated to the next management level. In this way the organization prevents that losses are tackled on lower levels too long. The goal of performance management is to monitor operational performance and to address and reduce deviations and variations as soon as possible. Excellent performance management leads to higher and more stable performance. It is easy to understand that we need to select those KPIs that are critical to the success of the organization. An overview of the most important production KPIs can be found further on. Benefits of performance management. “Performance control’ is more than just reporting KPIs and comparing actuals with budget or target values. The real challenge of performance control is expressed in the words: “being in control”. “Being in control” means having grip on the processes: understanding the processes, measure the right (key) performance indicators, know how to adjust the processes to meet the target values, report and stretch targets, make people accountable etc. Having a good performance control system and being in control give an organization a number of benefits: Achieving more stable and higher KPI values in the daily business: This main goal is already highlighted before. Every single employee contributes to achieving and maintaining KPI goals. Quick response to deviations and escalation of serious problems prevent variation and lack of action. Reducing variation and quick response to deviations lead to higher and more stable KPI values. The management shows focus on performing: © Stichting NAP, Nijkerk 22 Being consistent in the application of the performance control system has big cultural effects. The organization members learn that performance is top priority and that deviations are noticed and discussed. An important precondition is that the loss data, data processing, analysis and reported data are correct and accepted. Employees understand the importance of (Key) Performance Indicators: A Performance Indicator is much more specific than a Key Performance Indicator. A PI is directly connected to a source of loss, e.g. a routine stop, the average product weight, delay in a production plan on machine level et cetera. It is important that the employees understand the significance of the operational achievements for the sustainability of the organization. They must take responsibility in this for their part, and feel ownership for their PI’s. Therefore employees are part of the loss reduction process and the performance control process. The performance control system supports the empowerment of the employees: Translating KPIs into clearly related and relevant PI’s makes them understandable for the employees. The employees will understand their responsibility and how they can contribute. The KPIs and PI’s give them a clear insight in the effect of their actions on the results. This is a perfect basis for empowerment of the employees and stimulates their commitment to the organization. The performance control system is used to improve: The organization needs to show in practice that the focus is on problem solving and improving. The culture must be open, stimulating and constructive towards high performance. Employees must feel free to report deviations and search for solutions to prevent recurrences. If you would blame them for the deviations they would never report again. A positive attitude towards the performance control system is needed. All people involved, both management and employees, must see the KPIs, PI’s and the performance control system, as tools to measure the performance and to hold the gains. If not, they will develop resistance against them and the goals will not or only partly be realized. Performance control has a big effect on the operational results and the behavior of all employees. The first one is demonstrated by higher and more stable KPI levels. The second one is expressed in a culture of performance-oriented collaboration of people and departments. The degree of employee satisfaction will also increase. All organization members participate in the decision making process. They have more influence in the day to day business and can © Stichting NAP, Nijkerk 23 operate more autonomous. It also helps that there is much more clarity. Everybody knows what he or she is accountable for and what can be expected of the others. Choosing production KPIs KPIs and KPI target values are used to express the desired (or required) operational performances and to monitor the success rate of the improvement process. If the set of KPIs doesn’t reflect the operational priorities your organization will move in the wrong direction. Improving in the wrong direction is even worse than not improving at all! There are a few guidelines for the KPI selection process: Start with the mission and vision of the organization. The right KPIs are the ones that indicate that your mission and vision statement will become reality. Balance the different important topics for your organization. Make sure that you have one or a few KPIs in every subset, as described in the next paragraph. Choose the KPIs that cover your main losses. These losses reflect the difference between the current operational levels and the required ones. Which losses “keep you awake at night”? These areas must be covered by KPIs. To be successful a company must identify and operate in line with its so-called qualifiers and differentiators. Qualifiers are things all companies in a certain branch of industry must be capable of or must possess to survive on the long-term. For instance, if all major players each have an OEE in the range of 90-95 per cent, a company will generally not survive if it consistently has a level of 50 per cent. Qualifiers are so to say entry tickets to the Olympic Games. Differentiators are competitive advantages companies develop and maintain to beat the completion, like having superior product quality. In Olympic terms, differentiators get a company a gold medal. Evidently, KPIs selected at the strategic level should be fully in line with a company’s qualifiers and differentiators. In line with the above examples, OEE and product quality should be KPIs. The next figure demonstrates the relation between the discussed activities and the three policy levels. © Stichting NAP, Nijkerk 24 Main types of Key Performance Indicators Indicators are either leading or lagging. Leading indicators are metrics that are task specific. They respond faster than results metrics and are selected to indicate progress towards long term objectives. Leading indicators are indicators that measure and track performance before a problem arises. Leading indicators warn you to take corrective actions before the process gets out of control. Lagging indicators can be pinpointed as result KPIs. They are the milestones of the improvement journey. Organizations that meet their (challenging) targets are considered successful. A few examples to illustrate the difference between the two types of indicators. By monitoring the number of unsafe situations, near misses, medical treatments, injuries without illness leave or restricted work cases a company can manage the process of avoiding injuries leading to absenteeism. All these indicators are leading indicators. The lagging indicator is the Lost Time Accidents ratio. Another example can be found in the quality assurance process. The number of consumer complaints is a well-known lagging indicator. Quality assurance however goes much further than just reacting on complaints of consumers. A company needs to manage the quality assurance process and to monitor the performance. This can be done with a number of leading indicators such as scrap, first time right ratio and failure costs. The management could also decide to audit the quality control process. How well is this system executed? This score indicates the dedication, motivation and discipline of the organization in delivering quality to customers. In short, you could say that lagging indicators demonstrate the result were leading indicators enable the organization to manage their (improvement) processes. © Stichting NAP, Nijkerk 25 Performance levels in an organization working with CI in Production Performance levels in an organization that works with Continuous Improvement in Production (CIP) can be monitored by a large number of Key Performance Indicators. The challenge is to find or select a limited amount of performance indicators that are critical to the successful output of the process. Many organization make the mistake to define too many or too complicated KPIs. The table below shows the most important and commonly used KPIs. This overview is divided in seven subsets: Productivity, Quality, Costs, Delivery, Safety, Environment and Motivation/Engagement.

How are modern industrial automation systems able to make a significant contribution to continuous improvement processes? This section sets out a number of examples of specific software tools that can be used to improve quality and reduce losses. It also describes why the functionalities inherent within modern automation systems can effectively support continuous improvement processes. The essence of industrial automation systems Industrial automation landscapes can be divided into the following four system layers : Level 4 = Enterprise Resource Planning (ERP) level Level 3 = Manufacturing Execution/Information System (MES / MIS) level Level 2 = PLC – Scada / DCS level Programmable Logic Controller – Supervisory Control And Data Acquisition/Distributed Control System Level 1 = Field level See also the figure below. Each system layer fulfils a specific function within the automation landscape. The primary task of an industrial automation system is to control, operate and visualize a production process. In addition, Levels 2 and 3 increasingly offer important options for collating data on the production process. Sophisticated software tools can be used to © Stichting NAP, Nijkerk 28 convert this data into usable information to provide effective support in continuous improvement processes. As a result of increasing vertical integration, i.e. from Level 4 to Level 1, and growing local intelligence at field level, greater volumes of more accurate data are becoming available. Not only can the available information be deployed to improve the quality of the product and production process, it can also be used to reduce the various forms of loss. In short, modern industrial systems contribute to continuous improvement processes by making data on the production process transparent and making it possible to assess production data more quickly and effectively. Furthermore, they support the actual process of implementing the improvements as the data is available in real time. A good example of this is Overall Equipment Effectiveness (OEE). OEE is nothing new in itself, but by using modern integrated systems, we are able to view various losses more quickly and as a result determine the OEE. In addition, modern systems offer the tools for displaying effective dashboards and trends. Energy Management Systems (EMS) EMS systems tend to focus on energy losses. Plant owners can use an EMS system to ascertain how much energy is consumed by individual consumers as well as to show which process variables are responsible for these energy requirements. By making this data transparent and showing the various correlations, it is possible to come up with options for improvement and optimization so that energy losses are reduced. One of the most important improvement options is the prevention of (expensive) peak load by combining data on consumption with production planning. This is illustrated in the figure below. In addition, modern Energy Management Systems offer plant owners the reports they need for cost allocations, such as energy consumption per production unit, per ton of product or per batch. In addition, CO2 reports can be created to provide authorities with the information they require. Finally, EMS systems often provide the necessary functionality for managing energy optimization initiatives. © Stichting NAP, Nijkerk 29 Reducing losses in production also means reducing the use of raw materials and energy. In this respect, continuous improvement processes directly contribute to sustainability and the carbon footprint of a production process. Optimizing the total energy management, such as steam, water, gas and electricity, will have a positive impact on improving the sustainability of a production facility. Process Simulation Systems Process simulation provides us with a means of increasing the quality of production and reducing outage losses. By mathematically modeling the production process, it is possible to simulate the dynamic behavior of that process. The effect of an adjustment or change in the production process can be viewed in simulation mode. Once the change has been evaluated, it can be applied in practice. This prevents losses from outages as a result of an unplanned effect. In addition, Process Simulation offers benefits in terms of time when commissioning a production facility. It also serves as an excellent means of training users. Advanced Process Control (APC) APC is a generic term for all available software tools within Process Control Systems that can help further optimize controllers. APC can be used to tackle many types of loss, including energy losses and outage losses due to rejects. APC functions can be divided into the following three groups: © Stichting NAP, Nijkerk 30 Control Performance Management Extensions to PID control (Proportional-Integral-Derivative Controller) Multi-variable controller Control Performance Management The general term of “Control Performance Management” covers “Control Performance Monitoring” and “Optimization of Control Loops”. Empirical studies have shown that many of the control loops in the process industry do not meet all their requirements and that there is enormous potential for improvements, especially in the area of energy losses and speed losses. In many cases, people are not even aware of this potential. The term “open loops” (see figure above) here means that there is in fact only a means of control, there is no automatic closed-loop control. By way of analogy, a driver of a vehicle steps on the gas pedal so that it is depressed exactly half way and looks at how fast he is going, both uphill and downhill, with the vehicle loaded and unloaded. The driver himself is the controller if he wants to drive at exactly 50 km/h but can only take action if the impact of his action is visible on the odometer that records the distance traveled. The quality of cruise control is much better and more efficient. Plant operators or instrumentation and automation engineers do not have the opportunity in the course of their daily activities to permanently monitor the huge numbers of control loops for which they are responsible. So functionalities are needed to continuously monitor the performance of all loops in an automated way, with the aim of planning specific maintenance activities and retuning loops as soon as their performance deteriorates. By © Stichting NAP, Nijkerk 31 applying performance monitoring function blocks, it is possible to transparently ascertain which loops are meeting their performance targets and which are not. Extensions to PID control In addition to the standard PID controllers in a Process Control System, APC function blocks are available to further dynamize the P, I and D actions. It is therefore possible to ensure for example that specific process values can be regulated to attain their end values more quickly. This can play a role in reducing the overall volume of energy required, for example. Extra functions are also available for more effectively monitoring the outputs of the function blocks for example to control a valve. This enables us to predict when the requisite maintenance of such instruments should be carried out. For example, it only takes a few seconds for an effective valve to close, but if this time increases due to wear and tear, this additional time is detected and recorded by the controller. Because this wear and tear is a gradual thing, we will see a slowly emerging time variation, making it possible to make predictions. Multivariable controller (Model Predictive Control MPC) A multivariable control situation exists if one unit incorporates various manipulated variables (variables processed by a controller) as well as controlled (monitored) variables which then interact with each other. The aim of a process control system is to bring each controlled variable to an individual setpoint independently from the other controlled variables. This is time-consuming in practice, because moving a manipulated variable not only affects the associated controlled variables, it also affects all other controlled variables. A multivariable controller ensures that a distinction is made between a main controller and sub-controllers. By limiting the sub-controllers by means of a multivariable controller, it is possible to prevent errors. This will inevitably reduce losses due to outage. Typical empirical values of the benefits for APC solutions are: Increasing throughput by 1 to 5% Increasing yield by 2 to 10% Reducing energy consumption by 3 to 10% Reducing standard deviation of process variables by 25 to 50% of the previous value. © Stichting NAP, Nijkerk 32 Effects of reducing cost price of APC tools APC tools are currently integrated within Process Control Systems. In addition, it is becoming increasingly more straightforward – and in turn more cost-effective – to implement APC tools by applying templates. As a result, in addition to larger and more complex applications, Advanced Process Control becomes a more attractive option for small to mid-sized processes. One of the key consequences of this trend is that the condition of an instrument or installation can be ascertained with increasing accuracy. Based on this information, predictions can be made with greater precision and reliability with respect to the requisite maintenance in terms of the availability of the installation. Statistical Process Control (SPC) Statistical Process Control (SPC) is a solution deploying statistical techniques for monitoring and predicting how processes will run, specifically so that action can be taken in good time and thus prevent any process from going “out of control”. This prevents losses due to outage. The terms SPC (Statistical Process Control) and SQC (Statistical Quality Control) are often used interchangeably. Both approaches are based on the same principle, but when quality data is involved, reference is usually made to SQC. SPC in a modern Process Control system typically entails the in-line analyses of real-time process and quality data and then immediate adjustment of the process based on the results of these analyses. By applying automated statistical techniques based on on-line data, a trend can very quickly be detected so that the process can be quickly adjusted, if necessary in an automated way, by taking corrective actions. By adjusting the process in good time, it is possible to prevent a process from going beyond its limits. The most familiar statistical rules are the Nelson and Western Electric rules. The figure below graphically sets out three of the eight different Nelson rules. © Stichting NAP, Nijkerk 33 (source: http://en.wikipedia.org/wiki/Nelson_rules) By analyzing the process and quality data in this way, it is possible to identify patterns and trends that cannot be detected with the naked eye. SPC only helps when mapping the trends. Once a trend has been discovered, a root cause then has to be ascertained. By identifying the root cause and taking corrective actions, a trend can be (automatically) avoided in the future, thus making a process fully “in control”. The measured values are set out in a control chart (see figure below). The control chart shows the general trends and spread of the process and quality data over time. This information is used to effectively manage the process by ascertaining whether a specific variation in quality is attributable for a change in the process or for an arbitrary cause. A control chart comprises a centerline (CL) that usually also corresponds to the average value or target value, and the upper and lower control limits (UCL and LCL) that are ascertained based on the previous performance of the process. If the values of the parameter fall within the two control limits and no unusual trend arises, the process is considered as managed (under control). © Stichting NAP, Nijkerk 34 Note: It is also possible to apply two sets of control limits, which are then typically referred to as warning limits and action limits. Warning limits often correspond to a deviation of twice the standard deviation compared with the average value, and action limits to three times the standard deviation. By applying these statistical alarms and intervening in the process before anything is actually produced that does not comply with the specifications, it is possible to increase the percentage of “First Time Right” production, which also entails cost savings for a company (less reworking, scrap, non-conformity costs). In practice, statistical Excel and Minitab applications are used. The advantage of these applications is the statistical depth reached as well as the fact that these tools work offline from the process. However, SPC tools are integrated in the Process Control System and work in-line. In this way it is possible to make adjustments in the Process Control System more quickly (and automatically) by analyzing the root causes. Thanks to the real-time analyses, any alarms can also be generated more quickly. In addition to these advantages, the statistical analyses performed by an integrated SPC tool are context-based. For example, by comparing the analyses with production planning, it is possible to obtain additional insight into the value of the statistical analysis. Looking ahead, it is clear that it will be possible to make adjustments within a Process Control System with even greater accuracy thanks to the statistical analysis. This will inevitably lead to the ideal situation in which it will be possible to produce products 100% First Time Right. © Stichting NAP, Nijkerk 35 Overall Equipment Effectiveness (OEE) OEE tools help provide insight into the effectiveness of the installation and in turn ascertain potential for improvement so that capacity/output can be further optimized. OEE is the best known and most often used KPI. By using intelligent field equipment from Levels 1 and 2 such as intelligent Motor Management Systems, and intelligent process instrumentation, we are able to provide a wealth of information on the use of the installation at Level 3 (Manufacturing Execution/Information System). OEE reflects the degree of effectiveness to which an installation is used. OEE is calculated as “the number of good products over a period of time divided by the theoretically possible number of products over the same period of time”. To be able to improve OEE, it is important to map the various losses. The 6 loss categories are set out below: Routine downtime: These are pre-planned stoppages for which a standard is formulated. Logistical losses: These are problems in feeding and delivery. These losses may arise in the dimensions of people, equipment and products. In any event, the machine does not produce. Technical failures: These are stoppages lasting for over 10 minutes. To clear the stoppage, it is necessary to call in the services of maintenance personnel. Minor stoppages: These are stoppages lasting for less than 10 minutes. Machinists can clear these stoppages © Stichting NAP, Nijkerk 36 themselves. Speed losses: The machine is not meeting the planned number of units per minute due to causes other than those set out above (design capacity). Quality losses: The units produced do not comply with the specifications. After deducting all losses, you are left with the effective time, the denominator for the OEE ratio. Formula for calculating the OEE = Availability X Performance X Quality: Availability = Filling time / planned time Performance = Net machine time / filling time Quality = Effective time / net machine time Improving OEE is a lucrative business, because a 5% improvement with an OEE of 40%, for example, is equal to 12% more output with the same resources! A world-class OEE for discrete industry is based on a 90% degree of availability, a 95% degree of performance and a 99.5% degree of quality, resulting in an OEE of 85%. For the bulk process industry, this world-class OEE standard is higher, i.e. 95%. For the pharmaceutical industry, the standard is considerably lower, at about 65%. Pros and cons of entering OEE data manually Initially, manually entering OEE information will increase the operator’s commitment to finding out more about the effectiveness of the installation. However, over the course of time, it will become a more repetitive way of working and an automated solution is often more effective for retaining data integrity and reducing the amount of administrative tasks in the operator's workload. Such an automated solution offers accurate data with respect to downtime and reasons for downtime. In this way it is possible to identify trends and carry out improvements. Implementing OEE involves more than just installing a software tool. To successfully execute an OEE project, it is important to select the right parameters/variables and interpret them correctly. It is therefore important to obtain good advice in this respect. Condition Based Monitoring The aim of Total Productive Maintenance (TPM) is to carry out maintenance in such a way that the availability of the installation remains at a maximum level at minimum cost. Condition-based monitoring tools, such as intelligent Motor Control Centers, help by © Stichting NAP, Nijkerk 37 providing practical information so that the correct maintenance schedule can be set up. For example, the number of hours in service and time variables that give an indication of wear and tear. In addition, intelligent field equipment is increasingly designed with internal check mechanisms that constantly monitor the equipment’s own state of health. Process Analytical Technology (PAT) PAT focuses in particular on reducing waste and speed losses. The pharmaceutical industry is under pressure not just because of the economic climate but also and above all due to the rising development costs of new medicines coupled with major success products from the past becoming patent-free – generic producers are entering the market so margins are getting tighter. The traditional validation requirements imposed by the FDA (Food & Drug Administration) on pharmaceutical producers to date have greatly impeded the implementation of modern production techniques over the last few decades. In practice, this approach meant that a process could no longer be modified once it had been approved by the FDA. What’s more, the system was not exactly watertight, given the large number of “recalls” of products over the last few decades, plus the fact that many batches had to be destroyed after production, because they did not satisfy the quality requirements for launching products on the market. For this reason, the FDA has been actively looking for new technologies to achieve more reliable end product quality, while ensuring this is done in a more cost-effective way. This led to the publication by the FDA of a PAT guide in September 2004. PAT (“Process Analytical Technology”) is defined as “one system for designing, analyzing and checking production processes, based on measuring critical-to-quality attributes of raw materials, in-process materials and production processes in real time, with the aim of optimizing the process and ensuring the quality of the end product” (see the figure below). © Stichting NAP, Nijkerk 38 By measuring the critical-to-quality attributes in real time using a PAT system, and then comparing them, it is possible to make predictions about end product quality while the product is still in production. PAT is introduced in three stages: 1) Determine the critical-to-quality attributes (CQAs) of the process in question 2) Select the appropriate analytical techniques to measure these CQAs in real time 3) Use a PAT data management tool to collate all data in real time and compare this data so that predictions can be made about the end product quality It therefore involves more than just introducing PAT analyzers in the process. The appropriate IT solution for processing this data in real time and comparing it plays an equally important role. By strategically introducing PAT as a technology, it is possible to produce on a Right First Time basis and with greater efficiency. This real-time quality monitoring reduces or eliminates not only the need to carry out post-process testing but also production costs, sometimes to a considerable extent, while lowering the incidence of production losses. PAT introduces new data sources into the process to obtain a better overview and greater understanding of the process, while making it possible to manage the process more effectively. For example, the drying process of granulate: The end point used to be determined by measuring the output temperature. This approach seemed to result in a systematic drift compared with the target value after x batches. By introducing PAT using a Near Infra Red probe, a nicely concentrated residual moisture content value around the target value was obtained after drying, batch after batch, resulting in ”Right First time”. This meant no © Stichting NAP, Nijkerk 39 unnecessary energy losses and no re-working or scraps. Integrated Asset Lifecycle Management system (Comos) Integrated Asset or Plant Lifecycle Management systems optimize the engineering and maintenance process, thus helping to reduce losses in engineering and maintenance time. By improving coordination and cooperation during the initial engineering and lifecycle phase, engineering hours are saved and errors due to inconsistent information are significantly reduced. Integrated technical systems based on an object-oriented platform play a key role in reducing engineering effort, as a specific function only has to be defined once. A further advantage is the fact that a single definition ensures consistent data integrity and this definition is immediately available and comprehensible for the entire engineering team. Integrated engineering environments also ensure that changes and adjustments in the production process are integrated in a more straightforward way into the as-built documentation, which in turn keeps losses to a minimum which may arise through errors as a result of inconsistencies in the production lifecycle. Furthermore, an integrated Asset Lifecycle Management system provides accurate information on the installation, reflecting the integrity of the installation, so that effective and efficient preventive, corrective or even condition-based maintenance can be planned. In its capacity as a leading market research firm, ARC defined the following processes/subareas for Asset Lifecycle Management. (source: ARC, Enterprise Asset Mgt and Field service Mgt. Solutions (2011)) © Stichting NAP, Nijkerk 40 Interaction between plant owner and automation provider To make optimum use of the available tools within automation landscapes for supporting continuous improvement programs, it is crucial to ensure effective interaction between the plant owner and the technology partner. It is important for there to be a large degree of openness in discussions about the bottlenecks and KPIs. This calls for trust on both sides. The teams are then in a position to initiate an effective proposed improvement for each bottleneck. To further encourage interaction between the plant owner and technology partner teams, it can be useful to agree an incentive program. Examples of improvement topics include: Optimizing energy Increasing production output Improving logistical bottlenecks Enhancing the reliability of old systems Reducing maintenance costs Improving availability Optimizing parts management Reducing stoppages A critical success factor for this approach is to ensure the necessary commitment at senior management level on the side of the plant owner and supplier. In the future, there will inevitably be closer cooperation along the chain and more frequent sharing of process expertise, bottlenecks and use of systems and tools. This is partly because technical expertise among plant owners is dwindling as the population ages, and partly due to the scarcity of well trained technical students. Furthermore, plant owners increasingly see the acquisition and retention of technical expertise as a non-core activity and therefore outsource it. And finally: Knowledge is power! If we want to improve, then it is important for the facts to be clear and known, both with respect to the current situation and the desired situation. Modern industrial automation systems show (keep a tally of) the plant data and compare it with the desired values, in real time and transparently. Modern automation systems show in real time the effects of corrective actions that have been implemented and adjustments that have been made to ensure improvements. It can therefore be stated that a modern automation landscape has become an essential factor for successfully implementing a continuous improvement project. © Stichting NAP, Nijkerk 41 Continous improvements in Production: Quick wins. Introduction This section describes the importance of first “harvesting low-hanging fruit” for the sustainability of Continuous Improvement programs. Building a continuous improvement (CI) organization costs time and money. It is also not an easy task. It is impossible to consider the implementation of CI as a short term project capturing limited resources. The opposite is true. It is a step by step change management program which turns the company into an effective and efficient producer with almost no avoidable losses. A competitor that is hard to beat. Almost everybody wants to be that successful, only few achieve this goal. Almost 70% of planned change programs fail and this percentage is likely also applicable for CI programs. Companies start enthusiastically with CI. A lot of training and communication is done and the effort is quite huge. On the other hand, these time-consuming activities leave hardly any room for real improvements that contribute to the KPIs of the organization. It is mainly this dis-balance between efforts and results that kills many CI programs at an early stage. In order to avoid premature stops of CI initiatives, one should balancing efforts and results by harvesting on ‘low-hanging fruit’, i.e. quick wins. Although these quick wins are specific for individual companies there are some common fields were to look. Pareto analysis Time is limited and costly. The use of human resources must be managed carefully. We cannot improve everything at the same time. A tool which is very helpful in prioritizing CI activities is the Pareto principle. Basis of the Pareto principle is that by doing 20% of the work, 80% of the advantage of doing the entire job can be generated. Or in other words, a large majority of losses (80%) are produced by a few sources (20%). The CI organization needs to find the 20% sources of loss per KPI. By first tackling these sources of loss a major contribution to the improvement of the KPI value will be generated. Make sure that this analysis is fact-based. We need to improve on facts, not on assumptions. In practice we will hardly face a situation where the 20% is caused by more than 5 different sources of loss. Therefore this method is also known as “the top 5 method”. 5S 5S is a very powerful tool which can be implemented in a reasonably short time. 5S has one main goal: reducing the searching time of people dramatically. The quick win therefore is time. But 5S has more positive effects: It creates a safer working place. © Stichting NAP, Nijkerk 42 It creates more free space. Anomalies and losses become visible. It brings ownership to the people of the shop floor. It makes people proud of the working place. It motivates. Value Stream Mapping What is the use of optimizing something that has no added value? The answer is obvious, nothing. Surprisingly enough this common sense knowledge often doesn’t prevent companies from improving process steps that have no or little added value. This common mistake can be avoided by value stream mapping. Value stream mapping (VSM) is a visual technique used to identify and strip non value added steps out of a company's flow of information and materials. The end goal is to make the process free of wasted efforts. The seven sources of waste are explained in an earlier stage. VSM starts with the current state of a process. Information is gathered at the shop floor and the VSM team draws a picture of the current way of working, using standardized symbols. The process is then analyzed. Next the team comes up with improvement suggestions. All these improvements together are captured in the future state of the process. Finally this improved process is implemented. Root Cause Analysis The 5X Why tool is probably the most commonly used tool for finding the root cause of a problem. Implicit it is also a very good change indicator. CI organizations need to make a change in mindset and acting. They move from thinking and reporting in KPI results to thinking and acting in loss reduction activities. Those who succeed can be identified by the high number of successful and completed root cause analysis. Finding the root cause of a problem, followed by elimination of the source of that loss (the root cause) is very important for the sustainability of the realized improvement. The organization moves from firefighting to process control. A 5X Why analysis always starts with a sharp description of the problem that we can see. This is called the failure mode. This failure mode is no more and no less than a symptom of the underlying source of the problem, the root cause. The 5X Why analysis is performed by a multidisciplinary group of people qualified for this job. They start with asking themselves “why do we have this problem?”. They repeat the question till it makes no sense to bring up the next “Why question” anymore. Sometimes there will probably be more possible answers per question. Complete every line before © Stichting NAP, Nijkerk 43 moving to the next possible answer. It is possible to check the results of a 5X Why analysis. Start with the defined root cause and go back step by step to the problem definition. This by bringing up the explanation “that’s why” for every answer. In case this “that’s why” is not a logical conclusion as an outcome of a question the root cause can’t be right. KPI Alignment Successful companies always manage to align all the activities in the direction of the company goals. These goals are clear, and understood by everybody. Every single employee knows his contribution to the KPIs. Key word in this process is empowerment. Empowered people are in control. They know what to do and have the confidence that they are capable of doing it. There is room to manoeuvre, bring in new ideas and make judgment calls to a certain extent. The boundaries are also clear. Furthermore empowered people are satisfied with their job which they find meaningful. The cooperation with colleagues and other departments is considered of added value and demonstrated in day to day business. To facilitate this change process the management faces two priorities. The first one is about the set up a performance control system. The four elements have already been explained earlier. Briefly: KPI tree: Translate the company goals to performance indicators for every operational level. RACI matrix: Assignment of tasks, authority and responsibilities. Standardization of every frequent and planned stoppage. Monitoring progress and results via standardized short meetings. The second priority is about performance behavior training and coaching, an absolute necessity to correct performance problems as they arise within the organization. This is accomplished by first, identifying the root cause and secondly, implementing a plan of action to correct the problem. Training deals with knowledge and skills while coaching leads the employees to higher competence levels and overcomes performance barriers. Rewarding program We can learn a lot from teachers and coaches of young people. They reward juveniles for desired behavior and performance with compliments or small gifts like candies or a medal. Hardly ever they punish the students or players. They know by heart and experience that stimulating is much more effective than punishing. The balance for achieving the desired behavior and performance are at the stimulating side. Once in the professional environment we seem to lose this knowledge and change our © Stichting NAP, Nijkerk 44 approach to the punishing side. We tell people what they have done wrong and make clear that this kind of mistakes can’t be accepted (anymore). Sometimes this is necessary, but this should be the exception to the rule. And the rule is to make people clear, in a positive way, what the management wants and to stimulate both the behavior and the performance that contributes to the company goals. You know how to do that! 2 business cases. Business case #1: AkzoNobel. This theoretical background is an exerpt from a description of an AkzoNobel case, focusing on the business unit Industrial Chemicals (BU IC). A summary of this business case can be found in Annex 1; the relating interview that was held with AkzoNobel executives is listed in Annex 2. Operational excellence is a key success factor for a producer of commodity chemicals in a very competitive environment above product leadership and customer intimacy, but there is always a distribution over the three value disciplines (Tracey, Wiersema, Harvard Business Review Jan/Feb 1993), as depicted in the figure below: Operational Excellence Product Leadership Customer Intimacy Operational Excellence will drive “Safe and hassle free delivery at competitive cost” with a BU wide implemented methodology. It was clearly expressed that a strong top-down drive was considered necessary, targeting a cultural change in the organization. A target of a value creation of 1–2 % of the yearly total cost base was agreed by the participants. A taskforce, existing of senior manufacturing managers, was appointed focusing on the methodology to be used, and the requirements (design criteria) around the implementation: Target driven, coverinng all functional areas Top-down living of approach © Stichting NAP, Nijkerk 45 Top management commitment Empowerment/involvement of the whole organization Cultural change needed, from re-active to pro-active Approach should allow for local customizations Use a common language (to be developed) Clear and consistent communication Perspective for career development of participants Performance measurement Sustainable, long-term way of working instead of a cost-cutting tool Deliver 1-2% value creation on an annual basis (as % of total cost base) The task force decided to have a closer look at three proven continuous improvement methodologies, respectively Lean manufacturing, Six Sigma and the combination Lean Six Sigma. The QFD-tool (Quality Function Deployment, a Six Sigma tool) was used to look at the design criteria, and to make sure all requirements were covered. A detailed comparison was made between Lean and Six Sigma, summarized in the table below: Six Sigma Proven continuous improvement methodology, working on the basis of knowledge based decision making Operates at process level, driving effectiveness of all business processes. Starts and ends with the Customer. Utilizes a standard structured core improvement process for all projects. Tool usage is case specific and depends on project. Strong program governance structure which safeguards program and project delivery. Utilizes fulltime improvement resource that rotates through a Black belt role on a 2-3 year cycle. Projects are staffed by a mixture of fulltime and part time resources supplied by function/area where project is focused. Leadership development is a key deliverable from any deployment © Stichting NAP, Nijkerk Lean Proven continuous improvement methodology, working on the basis of waste identification and removal. Targeted at the complete value stream, with the central objective of maximizing value by removing all non value added activity and waste.(efficiency) Starts and ends with the Customer. He defines what is valuable to him, typically “anything he is willing to pay for”. Utilizes a core set of principles/rules to ensure project objectives and deployment is held true. Deployment and projects are primarily owned in the business and staffed by the business. Centralized mentoring and training is however normal. Easily accessible concepts and tools allow a broad base of participation even from early in deployment. 46 The table below shows identified Strengths and Weaknesses of Lean, respectively Six Sigma and the combination. From this, one can conclude that the weaknesses of one are in the main addressed by a strength existing in the other. This combined with their clear synergy in terms of goals and aims make them ideal partners. So the methodology of Lean Six Sigma was selected as the preferred one. Strength Lean: Easily accessible toolkit for all levels and produces results quickly Six Sigma: Extensive toolkit , to address process based problems (Effectiveness) Six Sigma: Utilizes fact based statistical analysis Six Sigma: Structured governance and project tracking. Six Sigma: Very structured core improvement process, which tools compliment. Lean and Six Sigma: Use Standard Vocabulary Lean: Toolkit focused on waste identification and removal (focused on Efficiency) Six Sigma: Structured talent development at all levels, particularly leaders/potential leaders Weaknesses Lean: Does not address process capability or variation in processes well Six Sigma: If applied without pragmatism can drive bureaucracy and benefits/delivery will suffer in terms of speed Six Sigma: Toolkit is heavily statistically biased and can be intimidating Lean: governance structure, relies heavily on individuals. No real project tracking and benefit delivery system (normally) Lean: Lack of a consistent really structured improvement process Six Sigma: Does not address waste identification and removal well. As a combination methodology Lean Six Sigma offers a highly structured approach which has the capability to deliver improvement in both effectiveness of process and efficiency of operation in a safe, risk managed environment. Lean Six Sigma combines the best of Lean with the best of Six Sigma and in doing so largely eradicates the weaknesses. It is not just a tool box with improvement tools that can be used in several occasions but it is more a philosophy or culture that should be anchored in the backbone of the organization. It takes time and resources to implement, but if it is made well it will sustain. Lean Six Sigma (L6S) was implemented from January 2010 in the BU. A L6S organization was set up to train Black Belts and Green Belts and to guide the introduction and to do the program management. An Operational Excellence director was appointed. Lean Six Sigma in AkzoNobel Industrial Chemicals is intended to be part of the Talent Factory and Management Development. Black Belts were selected from the group of high potentials in the company, the most talented people, giving them the opportunity to develop in a very challenging environment. The vacancies left behind by the Black Belt were filled by new talents. The Black Belts were trained in a six week program in waves of 5-6 people building © Stichting NAP, Nijkerk 47 up a group of about 15 Black Belts after 2 years. The Black Belts are 100% dedicated to the L6S program and return in the organization after 2 - 3 years at a middle management position to grow further and to strengthen the continuous improvement culture. The Green Belts are trained during 1 week and combine their daily work with an improvement project. They are guided by Black Belts. In another chapter more will be explained about the experiences with the L6S program between 2010 and 2012 and examples will be given of successful projects. L6S is has been worldwide proven as a very powerful methodology in numerous companies. A summary of Lean and Six Sigma is given below. Lean Lean is an improvement methodology to deliver optimal performance of the Value Stream to the Customer by identifying waste (Muda) in the organization, finding ways to remove it and implementing the necessary changes. Lean starts and ends with the customer, and aims to understand what is of value to the Customer. To be truly successful Lean must be adopted by the whole organization. It is more than a manufacturing based methodology. It uses a broad set of tools, ranging from basic to moderately complex. It operates by understanding the status quo, understanding the Customer and then closing the gap. As such it is very much a knowledge based methodology. “No blue eyed children and no sacred cows”. We listen and understand our customers’ requirements and what’s important to them. We drive improvement continuously whether the market requires it or not. With Lean we strive to do More with Less. Lean employs 5 Principles to drive improvement and if all changes are tested against these principles for applicability then few major errors will be made: Value: Establish value in the eyes of the customer. What does he really need? What are his expectations which he doesn’t even verbalize? “Something is of VALUE if the customer is happy and willing to pay for it” Value Stream: Understand the complete value stream, by (value stream) mapping everything from raw material to finished goods in the Customers hands. Identify waste wherever it is. Use Kaizen methodology to improve. Flow: Redesign the current Value Stream to eliminate the waste. Check for alignment to the Customer Values before making changes. Pull: Utilize the value stream only when the customer has a requirement, don’t process when no requirement but be flexible enough to instantaneously respond to customer demand. Perfection: © Stichting NAP, Nijkerk 48 When one round of improvements has been made, identify your next targets/opportunities and start again. Don’t wait to be forced to improve, improve pro-actively. In the context of Lean, “Waste” or “Muda” has been identified as “Anything the Customer does not want to pay for”. Waste is categorized by 7 types of waste: Correction, Over production, Material Movement, Motion, Waiting, Inventory, and Processing. Types of Work or Activity are divided into 3 categories (see figure below): Value Added is recognized by the customer and is happy to pay for. Non Value Added is not recognized by the customer and has not any value to him; activity is not needed and could be stopped immediately, often referred to as pure waste. Note: nonvalue-add = Waste. Necessary Non Value Added. The customer does not recognize any value to him, but activity is needed and could not be stopped immediately without undesirable nature results. Further work required to remove need for activity. Value Added Motion Non Value Added Necessary Non Value Added Non value Added = WASTE The applicability of Lean is primarily in the area of the performance of the Value Stream. It seeks to drive optimal performance and efficiency both in the Value Stream and within the supporting functions. Lean is applicable to every function in every organization. A totally lean and waste free organization doesn’t exist. The real question is where is waste most prevalent and can it be removed most effectively? Value Stream mapping sets out to answer this question and is the real starting point to understanding the opportunity to improve performance. © Stichting NAP, Nijkerk 49 The way Lean is implemented should follow the following set of rules or guidelines: A central sensei or master who has exceptional knowledge of Lean trains the organization in the principles and practices of Lean. The Trained organization, initially with assistance from the Sensei will assess itself, understands its own value streams and defines improvement opportunities. The organization will establish its priorities and drive improvement from within its own ranks; priorities are usually agreed through a central steering group/team. Progress is monitored through regular project updates, often on a monthly basis, updates either come through the steering group or often come through the regular business reporting cycle. Six Sigma Six Sigma is a knowledge based continuous improvement methodology aiming at the reduction of defects in a process. Six Sigma starts and ends with the customer. A product or service which is defect free and meets the customers’ expectations can only be accomplished if the customers’ expectations are properly understood if the internal processes of the organization are capable and fit to provide the service or product to the customer. The starting point of Six Sigma is knowledge based management. It uses a tool set which is built around existing statistical tools. What sets Six Sigma apart of other improvement methodologies is the core process (DMAIC) it uses: to drive improvement as an integral part of the daily job leading to consistency achievement of results the strong project and program management structure In a traditional organization, the focus of a problem is around the effect. Solutions are usually driven by intuition, gut feel and guesswork. The outputs or “Y’s” of a process will often appear on a management dashboard, and will be the measure of success or failure. A Six Sigma organization works quite differently. The solution to the problem will be driven by detailed understanding of the factors “X’s” involved in creating the result (Y) and particularly in understanding the “Critical X’s” which carry the most significance. And last but not least understand the statistical and mathematical relationship between the “Y’s” and the “X’s”: Y =f(x)’s. Changes are made based on knowledge; which “X’s” are key versus which are not. The DMAIC process ultimately delivers the Critical X’s and allows an optimal solution to be realized. DMAIC is intersected into 5 key phases: Define: Understand the business reasons driving the project and understand the Customer’s requirements. Define the potential benefits and savings. Measure: Establish current process performance. Confirm that the measurement system is capable and that data can be trusted. Create a measurement system to collect data if none currently exists. Create a formal project definition. Set improvement targets. © Stichting NAP, Nijkerk 50 Analyze: Detail understanding of the potential X’s and start filtering towards critical X’s. Route cause analysis methodologies employed. Improve: Confirm Critical X’s. Create solutions requirements specifications and drive potential solutions. Select solution, trial and refine. Implement refined solution. Control: Validate effects of solution, create process tolerances and document process capability. Define long-term process control mechanism, and produce out of control plan. Sign off the benefits case, close project documentation. Celebrate with the team. Before a project can move from one block to another it must pass a toll gate review, which is the primary project governance which ensures that the business requirements are met. Organizations which fail to realize the potential of Six Sigma are often frightened to stop a project at a tollgate when it has not delivered what it really should have. Failure to be thorough here will ultimately compromise the end solutions. The applicability of Six Sigma is in the area of Process Performance. All processes are not always capable or repeatable, their inputs are not always controlled and their outputs are often never measured, however they do exist. The challenge a Six Sigma project is that before it can start it must first create a system to collect data and measure current performance around the process under review. Six Sigma is factually a statistical term and refers to the stability and variation of a process. A Six Sigma process will produce only 3.4 defects for every 1 million repetitions or a first time yield of 99.99966%. A ‘Six Sigma process’ comes from the notion that if one has six standard deviations (six sigma) between the process mean and the nearest specification limit there will be practically no items that fail to meet specifications: The ’68-95-99.7’rule states that 68% of all measurements fall within the 1-sigma boundary i.e. 1 standard deviation; 95% falls within 2-sigma bandwidth and 99.7% falls within 3 sigma bandwidth, as shown in the figure below. Taking this forward, 99.9999998% of all measurements fall within the 6-sigma bandwidth. As process standard deviation goes up, or the mean of the process moves away from the center of the tolerance, fewer sigmas will fit between the mean and the nearest specification limit, increasing the likelihood of items outside specification. © Stichting NAP, Nijkerk 51 The heart of Six Sigma lies is process optimization and variation reduction. Every process conceptually at least should have limits which define whether the process has delivered on its prime purpose or not. In process performance terms we talk about Preciseness (spread or variation in results) and Accuracy (closeness to target value). There are 4 potential outcomes: Not precise, Not Accurate – high spread in combination with not close to the target value. Not Precise, Accurate – high spread but close to the target value. Precise, Not Accurate – low spread, not close to the target value. Precise, Accurate – low spread and close to the target value. Six Sigma aims to improve preciseness and accuracy. The way Six Sigma is implemented sets it apart from all other continuous improvement methodologies. For instance: It takes top class dedicated resources from the organization, invests intensive training and development in them and then uses them to drive business improvement as leader of an improvement team. It is recognized that change should be driven from all levels of the organization and training is tailored to facilitate this using the capability of individuals ranging from Master Black Belts to Black Belts, to Green Belts and in some organizations Yellow Belts. Green and Yellow belts drive change in combination with fulfilling their daily job. All projects are scoped for financial benefit before they begin and benefits are tracked through the project life cycle and for a further 3 years after completion. Improvement targets are jointly owned by the Six Sigma group and by the Business Implementation is top down and bottom up. Senior Executives support and live the values of Six Sigma, demonstrating commitment. Projects are executed by the organization and led by a dedicated trained resource (Black Belt or Green Belt) Six Sigma Black Belts are selected from the organization to serve deploying Six Sigma and leading business change and improvement during 2-3 years. It has two key purposes: 1) It provides a fabulous training ground to develop leadership skills as the black belt is forced to create and implement change with his team that he must positively influence to achieve positive results. 2) It spreads the knowledge and capability invested into black belts widely, when Black Belts return into key roles in the organization and doing the daily job with Six Sigma naturally. Selecting a Black belt is based on the following criteria: an identified High Potential employee, who usually has received well above average performance appraisals; he or she has demonstrated flair for improvement within the sphere of his current responsibilities; good communication and interpersonal skills; intellectual potential to master statistics etc. “The correct candidates will always be the ones you can afford to release the least” Black belt training typically takes 6 weeks in most organizations. © Stichting NAP, Nijkerk 52 Lean Six Sigma Lean Six Sigma follows the Six Sigma implementation approach in terms of roles and organizational structure. It also utilizes the Six Sigma governance structure with some modifications to recognize that the scope is wider and includes the overall value stream as well as process performance. Lean Six Sigma uses the DMAIC approach (see picture below : DMAIC cycle) and supplements this with the 5 Steps to Lean used as a set of rules to ensure projects are being driven and selected in line with Lean expectations. It is recommended to use and incorporate a Change Acceleration process with DMAIC. The combination enhances progress and ensures full stakeholder alignment and engagement at all stages from project identification to implementation and benefit realization, as is visualized in the picture below.

Business case #2: Royal FrieslandCampina. Route 2020 is the leading strategy in the company. This long term company wide strategy deals with WHAT FrieslandCampina wants to achieve in the coming years. To make clear HOW this will be done there is a need for a more tactical and operational approach. The Supply Chain organization of FrieslandCampina decided to realize her contribution to the route 2020 targets with a continuous improvement programme under the name World Class Operations Management (WCOM). A summary of this business case can be found in Annex 3. FrieslandCampina is organised in 4 Business Groups: From a Supply Chain view a Business Group consists of a number of production locations (Supply Points). Every Supply Point has a number of production facilities, all with their own continuous improvement plan. There is a good reason for that. The driving force for continuous improvement is the local management with their ambitions and goals. The central part of continuous improvement is the WCOM approach. We share the mission and the improvement tools. For the rest continuous improvement is a local responsibility. © Stichting NAP, Nijkerk 54 We will describe the continuous improvement process for a single Supply Point in the Business Group Consumer Products Europe. An overview of the improvement approach is visualized in the next figure: PLAN: Target settings and improvement planning The general direction for every single production facility comes from the mission statement of FrieslandCampina Supply Chain CPE (Consumer Products Europe): © Stichting NAP, Nijkerk 55 Mission: To be a reliable, cost conscious producer of dairy products, meeting the market requirements of our customers. Goal: To produce our products in safe working conditions, with due care for the environment, to the agreed quality and service levels, to the then lowest possible costs. The target setting process starts with the plant mission and vision by the local plant management team. The target setting and improvement planning process is conducted by this management team (top down approach) and is divided in 5 steps. KPI selection The FrieslandCampina Supply Chain has a set of definitions covering the complete range of 47 KPIs. Using common definitions assures that the calculation of the value of the KPI is the same in every plant and that benchmarking operational performances is easier to do. 10 out of this set of 47 are obligatory for every plant since these KPIs are applicable for every single Supply Point. These 10 KPIs are captured in the table: The production locations are free to add more relevant KPIs from the KPI set. Target setting After the KPI set is completed the plant will express her ambition level via the target levels. There are a number of criteria for the targets. They must be Specific, Measurable, Attainable, Relevant and Timely (SMART). The table contains 5 columns. The year To Date value of the running year acts as reference. What did the plant achieve so far? The target value for the next year, in this example 2013, is the same value as agreed during the budget cycle. The plant management also commits herself for the mid long period, in the example 2014 and 2015. The last (but not the least) column is for the indication of the World Class targets that the plant wants to achieve in the long term. When all avoidable losses are eliminated, which KPI levels will appear as the results of these improvements? © Stichting NAP, Nijkerk 56 Loss analysis A plant that wants to reach World Class levels, and isn’t there yet, needs to improve to get there. In most cases there is quite a gap between the current performance and the desired performance in the next year. So the question is: “how are we going to realize those improved operational levels?”. Managing results is not possible. You can measure results but you can’t manage or improve them directly. Results are the outcomes of improvement activities and that process you can manage. Improving is synonymous to loss reduction. What we consider as losses is explained in the previous chapter: “Waste/Muda” – Anything the Customer does not want to pay for – the Japanese word for waste. So we can improve the results by eliminating or reducing the losses. In the loss analysis process the sources of losses are identified and they are ranked according to their improvement potential. Improvement planning The activities in this step are often summarized with the term “close the loop”. In short this means that the sum of the planned improvements is at least equal to the gap between current and desired operational performances. By planning a bit more improvement results than strictly needed to close the gap we create some room to move for ourselves. This step is much more than just an indication. In fact it is a complete team planning for the next year based on the identified sources of loss. The team targets are also based on SMART criteria. A weak point in this process is the late involvement of the improvement teams. The management calculates the potential savings. The improvement teams do not yet exist so they can’t be involved in the target setting process at this stage, possibly leading to low commitment. Calculation financial impact As stated in the motivation part at the beginning of this paragraph costs savings are very important for FrieslandCampina. Financial values also enable us to compare the different KPIs amongst each other. It is nearly impossible to choose between e.g. OEE losses and productivity losses other than over (potential) € savings. The potential savings must have enough impact to put continuous improvement high on the management agenda. Later we can compare the realized savings with the planned savings to evaluate the savings plan conformance (savings effectiveness). After this step the planning phase is completed. We know what we need to do to meet our targets. We are ready to “do the right things”. © Stichting NAP, Nijkerk 57 DO: Improving The improvement plan is executed in this phase. All employees, both management and shop floor, are contributing. To make sure that every single employee knows exactly what his contribution is, a formal and strict agreement on roles and responsibilities is crucial for success. FrieslandCampina uses the RACI matrix to address these questions: R = Responsible, the executor of the action. A = Accountable, the person that approves the action, generally the manager of “Responsible”. C = Consulted, contributes to the action and gives feedback that is taken into account. I = Informed, needs to know but that is all, no dialogue. Defining the RACI matrix is not a one-off action. Every important improvement activity is subject to RACI definitions. Only then we avoid that roles and responsibilities are not clear and it is a boundary condition for good cooperation in the team. We want the improvements visible on the shop floor and not only in plans on paper. Furthermore is it of vital importance to involve all employees in the improvement process. FrieslandCampina uses two tools for this; an initial clean out and 5S. An initial clean out is mainly used to demonstrate the potential speed and high impact of continuous improvement, and to motivate the people. The goal is to create a starting point for improvements. A dirty machine with lots of problems and stops in a messy environment isn’t exactly an inspiring place to start improvements. We better make sure that we have a solid foundation for future improvements. We don’t build houses without a sufficient concrete foundation, either. Typical initial clean out activities are cleaning, labeling and eliminating small deviations, restoring equipment and restoring machine parameters. An initial clean out event is executed in one day maximum, depending on the size of the object and the number of participants. Off course the shop floor is heavily involved and in the lead. But other groups like the (top) management, machine builders and other suppliers are invited to join and help. This is highly motivating the work force. The importance of their work space is recognized and appreciated. 5S is a well-known technique. The objectives of 5S are not limited to a clean and shiny working place. Its outcomes also have a big impact on safety, motivation, waste reduction and even on productivity by reducing searching time. The five steps in short: 1) 2) 3) 4) Sort: Removing wastes and clearing the work area. Set in Order: Designating and labeling locations of work tools. Shine: Cleaning and improving the appearance of the workplace. Standardize: Documenting the work method, using standard tools, and sharing the best © Stichting NAP, Nijkerk 58 practices. 5) Sustain: Maintaining improvement, controlling work methods, and integrating the 5S's into the culture. Only after the initial clean out and 5S it is time to build the formal WCOM (World Class Operations Management) pillar organization. Pillars are characterized as “A team with a system made up of a set of improvement methods and management systems oriented to eliminating a set of losses, supporting the production in reaching their targets”. These pillars are an important part of the WCOM approach. It is fair to say that the execution of the improvement activities rely on the pillars. The pillars task can be divided in two main categories: 1) Building an improved way of working. 2) Managing the improvement teams. The pillar house of the FrieslandCampina Supply Chain is visualized in the next figure: The pillars are cross-functional teams that are responsible for the improvement of the working methods and the reduction of the losses. As we can see in the figure pillars are specialists in certain fields. Focused Improvement is the expert in productivity improvements, performance control and routine stops reduction. Planned Maintenance is the specialist dealing with maintenance optimization, breakdown reduction and speed loss reduction, et cetera. Becoming World Class is a long journey. To facilitate the pillars in this process FrieslandCampina uses pillar routes. The routes are a step by step approach enabling the different pillars to gather knowledge and experience. The different steps are subdivided in specific result fields, making clear what exactly should be achieved after completion. The pillars base their action plans on these desired outcomes. © Stichting NAP, Nijkerk 59 The Pillars also have an important task in managing the teams. An in-depth loss analysis results in an improvement planning. The teams that must bring these improvements are empowered by the pillars with means like e.g. time, (small amounts of) money, training and improvement routes. The improvement teams also have specific improvement routes. Like the pillar routes the aim is to increase speed and results by providing a standard with proven success. The routes are tailored to the losses, e.g. a single Minute Exchange of Die improvement route for routine stoppages. All routes have one thing in common. They follow the Plan-Do-Check-Act and Sustain approach. After the planning phase we were ready to “do the right things”. Once the improving phase is completed we are also ready to “do the things right”. CHECK: holding the gains A positive trend will only emerge when we add improvements on top of each other. But what is the use of this when we can’t hold the gains? We will report improvement result after improvement result but the trend on the KPIs will be flat. It is vitally important to sustain the improvements. This is a joint responsibility of every single employee. There are a number of boundary conditions which FrieslandCampina is very keen to meet. The most important ones are: 1) The main KPIs are monitored, preferably with an automatic system. Example is the real time and web based OEE monitoring tool. 2) Improvement teams are managed in a proper way so they bring results in time. 3) Cost savings are reported in a standardized manner and strictly followed. When these boundary conditions are met it is possible to hold the gains in a structured way. In every factory FrieslandCampina has a Performance Control System in place. This system contains four main elements: 1) KPI tree. Translating the factory KPIs to PI’s on operational level. It is e.g. impossible to make an operator solely responsible for the OEE performance level of his machine. He depends on the planning department for the number of routine stops, the technical department for preventing or solving breakdowns and other departments like processing and logistics for supply failures. But the operator is primary responsible for the duration of routine stops, the number and duration of short stops and the number of off-spec products. That are much better indicators to monitor and steer the operator performance then “the container” OEE. 2) The RACI matrix for these PI’s. 3) A standard for every routine stop. These stops have a high frequency and are planned in advance. They should be performed in the same way every time. A standard is an ideal enabler for this aim. The minimum level is a best practice level. The optimal is, of course, in © Stichting NAP, Nijkerk 60 line with the world class standard of this routine stop. These standards come from the achievements of the (SMED) improvement teams. 4) A meeting structure. In these meetings the operational performances are monitored and discussed. Meetings are held on shift-, daily-, weekly- and monthly level. If the achievements are lower than expected, corrective actions are taken. This on the lowest possible level. Every meeting has a specific standard with an agenda, participants, meeting goals, output specification and meeting agreements. Duration is minimal and expressed in minutes. The effectiveness of every meeting is measured. As you can imagine by now, this measurement is also standardized. Furthermore there is an escalation procedure in place. What can’t be solved in a shift handover will be addressed in the daily meeting. The remaining issues for the daily meeting are handed over to the weekly meeting et cetera. The second large component in holding the gains is auditing. The saying that “you don’t get what you expect but what you inspect” turns out to be true during the auditing process. FrieslandCampina conducts audits on three levels: 1) Team audits. Teams are extremely important. They bring the improvements in the important performance categories (KPIs). The ‘close the loop’ activity in the planning phase is executed in the do phase by the different teams. Progress and results of the improvement process are the responsibility of the teams, but the improvement process per team is monitored via auditing. Results of the audits are reported to the steering committee. 2) Pillar audits. As expressed earlier, the pillars have two main tasks: develop a world class working method in their own working area and managing the improvement teams. Pillar audits measure the speed and quality of these two processes. 3) Plant audits. A yearly event in which the complete improvement system is valued. FrieslandCampina has a standard audit format in which every desired outcome is described in a 5 point scale. The 6 audit elements are change management, costs and benefits, KPI results, performance control, pillars and teams. The total audit score is expressed in a percentage of the ideal score (100%). Plants can achieve four performance levels over time: bronze (40%), silver (60%), gold (80%) and world class >90%). © Stichting NAP, Nijkerk 61 ACT: System evaluation Also once a year the management team of the plant conducts a system evaluation by means of a SWOT analysis. The plant audit is an important input document for this analysis. Opportunities and threats from outside the factory are combined with internal strengths and weaknesses. The results of the analysis are captured in an action plan. This action plan is used as input for the planning phase. The PDCA improvement cycle keeps moving to the next level. Improvement results Without any doubts or hesitation FrieslandCampina can say that the continuous improvement program WCOM turned out to be a good investment. The benefits are both financial and non-financial. The most important results are: OEE increase; Productivity improvement (units per man-hour); Elimination of sources of product loss and packaging material loss; Elimination of sources of failure costs; Becoming more competitive via conversion cost reduction. The biggest learnings After conducting several SWOT analyses we concluded that: WCOM is a very powerful improvement programme. Commitment from top management is crucial for success. Knowledge of continuous improvement/WCOM is important, but knowledge of and capabilities in change management are even more important. WCOM is very cost-efficient. Payback times of less than 4 months are certainly no exception to the rule. There is a strong correlation between holding the gains and the Performance Control system; the factories that have a good working Performance Control system are the ones that hold the gains. Sometimes we lack detailed loss information in certain loss categories. Better knowledge of (the sources of) losses would unfold even more improvement opportunities. © Stichting NAP, Nijkerk 62 Comparing the two business cases. Two main approaches have been extensively described and discussed. Their key characteristics are summarized below. AKZONOBEL INDUSTRIAL CHEMICALS: Lean Six Sigma Driven by top management Strong management commitment/ownership at all levels from the beginning Embedded in Vision & Strategy Both process effectiveness and operating efficiency Ex-ante cost reduction target of 1-2% p.a. BU-wide Tracking (quarterly) of financial benefits (EBIT) Tool for change of culture Proven methodology Revolving full-time, dedicated improvement leaders Black Belts play a distinct key role and report to MT Opportunity for personal promotion Thorough training Talent Development and improvement clearly linked (high-potential Black Belts) Operational Excellence Director at MT level All levels of the organization, top-down and bottom-up Improvement integral part of daily work Improvement encompasses all activities (it is the way we work, the only way) FRIESLANDCAMPINA World-class Operations Management (WCOM) Embedded in Vision & Strategy Local plant (not site) management driving force Strategy and WCOM improvement toolkit are shared company-wide, but implementation is a local plant responsibility. Local plant management responsible for target setting and improvement planning Broad range of targets in KPI-terms over time; Performance Control Systems Focus on loss reduction Cost savings ex-post Broad involvement of all employees in ‘DO’ stage (only) Formal and strict agreement on roles and responsibilities Quick wins (on the shop floor) Cross-functional teams Reliance on specialists (e.g. for planned maintenance) Three-level auditing Both methodologies have their advantages and disadvantages and it would be difficult to tell which method is to be preferred. That would depend on the type of company: its culture & © Stichting NAP, Nijkerk 63 history, its productmarkets, its management style and the industry it is part of. Nonetheless, some similarities and differences are apparent when evaluating the above lists. Clearly, both methodologies are tried and tested in practice and both AkzoNobel Industrial Chemicals and FrieslandCampina embraced Continuous Improvement to spearhead their strategy. In both cases, no effort was spared to develop and introduce continuous improvement throughout the organization and, more importantly, keep momentum afterwards to make CI its way of thinking and acting. At AkzoNobel, CI is very much organized top-down and BU-wide, with strong topmanagement commitment and involvement. At FrieslandCampina, CI is primarily a local plant (not site) management responsibility, but local management is bound to implement corporate strategy and use common corporate CI tools & methods, including for instance the definition of important KPIs. AkzoNobel sets distinct cost reduction targets for the whole business unit in advance and controls operating profit (EBIT) on an ongoing quarterly basis. At FrieslandCampina, cost savings are more the result of an individual plant’s annual CI plan, discussed with and approved by the next management level. A key difference is that with AkzoNobel L6S is an integral part of management development: young, talented staff is freed-up, trained and assigned full-time to lead a CI project for a number of years. As Black Belt they report directly to a management team member. Promotion is likely, once the project is successfully completed. The number of employees that have been involved in CI projects at various levels (of belt colors) increases year after year, immersing the whole organization in a CI mode of working. FrieslandCampina organizes its CI activities more in a hands-on manner, close to the shopfloor of a given production plant. Teams play a key role particularly when implementing the CI plans. Potential areas for improvement are identified at the individual production plant level at Friesland Campina, while, at AkzoNobel, this is done at higher levels in the organization attempting to address areas that are of common interest to a set of (similar) plants. Benchmarking of the performance of a given set of plants is standard practice at AkzoNobel, at FrieslandCampina it is practiced in an informal way only. Similarly, there is little crossplant coordination at FrieslandCampina. Another difference with AkzoNobel is that approaches to Continuous Improvement differ between the various business groups within FrieslandCampina (some groups having a more centralized approach than others). The above concise analysis shows that Continuous Improvement can be approached and organized in completely different ways. It is also seen that a company contemplating the introduction of Continuous Improvement faces a great many choices. Continuous Improvement is a powerful tool for bringing organizations to the next level excellence, but © Stichting NAP, Nijkerk 64 the effort to select and introduce the appropriate methodology should certainly not be underestimated. Lastly, taking the perspective of the NAP Network, it of interest to note that both of the above systems fail to directly address the issue of improving the organization together with its client and supplier partners (or more general: its stakeholders). It is recommended that NAP takes the initiative to fill this gap. © Stichting NAP, Nijkerk 65 Part 2 : Asset and Maintenance management. General introduction. The stream ‘Asset & Maintenance management’ of the SIG ‘2x2 OpEx’ has chosen to give an overview of best practices in today’s Asset and Maintenance management, including crucial success factors determining excellent Asset and Maintenance management.This section also describes some theoretical background and common practices in this field. In describing the best practices we started from the premisse that maintaining (process) installations is an integrated part of the overall business process, including variables like stakeholders, changing market situations, and the human factor. This is the key to achieving the goal as defined by the SIG 2x2 OpEx. The overall goal of the SIG ‘2x2 OpEx’ is to find ways to optimize Life Cycle Costs (LCC, operational costs), or even lower these costs significantly. Studies have shown that an optimal Asset management (installations mgt) and Maintenance management can deliver cost savings from 15 to 30% of LCC. Based on an estimated invested capital of € 1800 billion (the Netherlands, process industry only), this is a significant financial gain! Please note that via the Internet a wide range of knowledge can be obtained, through literature, courses, methods and systems. We leave it up to the reader to search for additional material. History. In the past, NAP has already been investigating on the topic of “2x2”, including Asset and Maintenance management. A short summary: 2002: NAP SIG 2x2 Project ‘Your choice for projects, twice as cost, effective, twice as fast’ 2008: NAP SIG 2x2 ‘Front End Loading Strategy’. 10 years ago the importance of Value Improving Practices and ICT Tooling was already recognized; e.g. through methods like Collaborative Engineering (life cycle engineering: taking maintenance into account during the design process) and Predictive Maintenance (setting up long-term maintenance plans during the design phase of an installation). Asset and Maintenance management is a co-existence of developed specifications for technology, processes and concepts, structures and systems, instruments, other assets (like spare parts), raw materials, budgets and procedures. Especially the human factor – the employee with specific knowledge and competences – is the main factor contributing to an excellent Asset and Maintenance management. © Stichting NAP, Nijkerk 66 Unfortunately, this is not always recognized, nor appreciated, in the services industry. Performance management, focusing on KPI setting/measurements and financial performances, tends to prioritize to tangible results only (i.e. the Anglo-Saxon model); the contributions of synergy, collaboration and expertise (i.e. the Rhine-lands model) is less appreciated. This trend has a big impact on culture and on the loyalty of employees, and is very often underestimated. Delivering services is all about interaction between people and partly synchronizing (technical) processes. The A&M organisation to support all this is characterized by the interaction of functions held together in a formal structure. Understanding and appreciating the accompanying culture will have a big added value to the peformance of Asset and Maintenance management. Acknowledgements. The following persons contributed on the topic of Asset and Mainenance management for the SIG 2x2 OpEx of NAP: Joep van Aggelen (AkzoNobel) Ron van Empel (Royal HaskoningDHV) Dennis Willemsen (Siemens) With additional contributions from: Eduard van Emmerik (Emmerik consulting, previous: AkzoNobel) Nils Bosma (Shell) Ricardo Parrada Curros (AkzoNobel) © Stichting NAP, Nijkerk 67 Introduction to Asset and Maintenance management. Asset management (a financial term) in practice means ‘managing costs as a good operational management practice and achieving an optimal return on investment and optimal operational costs needed to manage installations and resources (people, spare parts) ; . Asset management is also about balancing between Performance, Risks and Costs of Assets during the entire life cycle. This is congruent with the definitions in PAS55 / ISO 55000. The replacement value of an installation is key to express quality in ratios and/or (K)PI. This is also expressed in Total Cost of Ownership (TCO) and/or Life Cycle Costing. Maintenance management is the total of people, means, budgets, spare parts and technologies used to ensure that installations meet all functional specifications during their life cycle. Conditions are determined by legal provisions, the market, the owner and operator of installations. In real life, these are often the ‘customers’ of the Maintenance function. Best practices are determined based on performances! For maintenance this often means that concepts and views are adjusted once measurements and analyses show opportunities for improvement. This is often referred to as Maintenance Engineering. These corrections – made afterwards – often lead to high operational and maintenance costs, and even costs of loss generated by unreliable technical availability and malfunctions. Loss of quality can also lead to less overall results. When striving for Maintenance Excellence, not only the efficiency of maintenance needs to be considered, but also – and even more so – the effort to prevent (corrective) maintenance and malfunctions. This aspect of a reliable and sustainable Asset Management holds a potential to tremendous (operational) improvements. Needless to say this requires a longterm vision on, and willingness to invest in, Asset Management improvements. Looking back 10 years, why haven’t we advanced beyond the observation that an integral approach of a project design, including the impact on operations/usage after “technical ready” can and should improve!? (see also the NAP report SIG 2x2 Project). The output of the design process influences future costs directly ; from an efficiency point of view these costs should be minimal, and (safety and security) risks should be better controllable. Why do we learn and act so little using the knowledge of others? In 10 years time, will we be asking ourselves these same questions again, of will we raise our standards and will we make progress? We conclude – both from theory and in practice – that improvement/savings opportunities as much as 15-30% of LCC remain, provided we embed our best practices and continue to innovate! © Stichting NAP, Nijkerk 68 Maintenance. Maintenance in the manufacturing chain This integral model of the Manufacturing chain depicts the most important functions adding value in the process from raw materials to finished products. Every manufacturing process consists of a primary process – the straight line – i.e. the activities that can be linked directly to the product. The secondary line represents the supporting functions. These are no core activities and are judged against level of efficiency and direct added value to the primary process. In general, these functions are shortlisted to be outsourced when assessing for efficiency improvement steps: the effort needed to execute these types of processes is not wanted, the specialized skills are often not (sufficiently) present in the organisation and more importantly, in general it is felt that fixed costs can be lowered, i.e. efficiency can be improved. The costs of Asset Management are managed in a more flexible way. Another perception is that labour costs can be lowered. Quite often it is not recognized that the end responsibility remains at the outsourcing party. Focusing on the right priorities regarding functions and processes will lead to effective decision-making. Important considerations: • Any manufacturing process can only be succesfull when it complies with the client’s wishes © Stichting NAP, Nijkerk 69 • • Any manufacturing process can only be succesfull for the owner if it generates a positive return on investment The basis for any manufacturing process is an integrated chain, i.e.: a sustainable improvement can only be possible if the total of all functions are considered. This applies to maintenance processes, too: the efficiency and effectiveness is often determined for more than 70% by other functions than maintenance itself, e.g. functions like Process Technology and Design. Benefits: Model enabling setting right priorities for Strategy of Continuous Improvement. Applications: useful for managers explaining Change management and creation of goals. Maintenance during downtime of installations In the context of Performance Management maintenance costs are often expressed as a KPI: Maintenance Costs / Replacement Value (MC/RV). Normally this KPI varies between 1.2 and 4.5%, sometimes a bit higher, depending on the situation. In addition, maintenance costs are part of the fixed operational costs, in the Chemicals/Coatings sector expressed as KPI varying between 10 and 25%. From a financial perspective it is only common sense to manage towards minimal MC. Therefore a lot of time and effort is spent on efficiency of the maintenance process. However, loss costs can be a multitude of the MC due to malfunctions and inefficiencies of work processes; this is not always recognized and valued as such. The reliability, and competitive position of a company can improve substantially if management would aim its strategy of cost control more towards process improvements, e.g. by deploying Lean Management and/or TPM. © Stichting NAP, Nijkerk 70 = Production quantity = Actual maintenance costs = Analysis, communic., start-up =Production losses ProProProduction losses The above figure depicts losses during a malfunction situation. Focusing on maintenance alone distracts from other disturbing factors and eventually performance. Looking at maintenance as a cost center is correct, however it represents only a small part in the total of the collaborative operational process. The integrated approach on KPI level to manage performance is expressed by ‘OEE’, Operational Equipment Efficiency. Important considerations: Management must be willing to acknowledge that an integrated approach can lead to better results Management should invest in cross-functional collaboration, TPM and involvement and attitude Management should invest in reporting, trending, analysis methodologies, work process improvements. Results are visible quicker and contribute to integrated process improvements. Especially the Technology, Production and Maintenance / Engineering functions will benefit. © Stichting NAP, Nijkerk 71 Maintenance in the design process. The expenditure associated with the maintenance of production equipment often amounts to several times the investment costs. Maintenance is a “wide-ranging subject” that must be reviewed during the entire life-cycle of an installation: from initial definition of the requirements, design, implementation, use, overhaul and modernization to dismantling. In 2002 The NAP SIG 2x2 Project published the paper 2x2, ‘Your choice for projects, twice as cost effective, twice as fast’. And in 2008 the publication ‘Front End Loading Strategy’. Both publication focus on CAPEX and on the importance of making good choices in engineering processes and plants. These studies focused around streamlining the design process, thereby achieving cost savings on the final investments (CAPEX). Result of the 2x2 project approach. Excellent project results can be realized by benefiting to the greatest possible extent from the following four components: 1) Using organizational, innovative and strategic methods for translating business objectives into the project development process can cut schedule and cost between 15-25%. 2) Using innovative methods such as variant design, new process technology, ICT tools and value improving practices can realize 25-30% in cost and 15-25% schedule reduction according to an analysis of the best and worst projects worldwide. 3) Stimulating integration between contractual parties (NAPred) through alliances can cut CAPEX to 20-30% and schedule tot 15-30% which is regarded as state of the art. 4) Use and understanding of the advantage of standard work processes for project development in the business and in projects, which is a precondition for good performance. Performance analysis model. Each organisation needs its processes evaluated on a regular basis. This also applies to the Asset and Maintenance organisation. In order to have a thorough evaluation done, an integral check is mandatory, i.e. not only looking from the financial perspective, but taking into account all functions and processes that add value to the overall operations. Any organisation is an interacting collection of agents contributing to the overall result each from its own (sub)function. © Stichting NAP, Nijkerk 72 STRATEGY Finance & control, Procurement, IT QHS &S, HR KNOWLEDGE LOGISTICS EXECUTION Technology Process/maint.

Planning Warehouses / shipping Packaging / spare parts Contracts (mgt) Production Maintenance General services Contractor supervision Projects (construction) The performance analysis model as represented in the figure above, shows the core and sub functions of the Asset & Maintenance organisation. When analyzing processes these (sub)functions should be taken into account in order to obtain a sound evaluation. We should distinguish the main objectives of the Asset organisation versus the Maintenance organisation. The Maintenance management function aims to maximize a safe, efficient and reliable execution of concepts; the Asset management function focuses on (maximizing) the effectivity of the invested effort and invested capital. This leads to a transparent, reliable and safe production installation where costs are managed effectively. An important observation can be made here. In order to have an optimal execution of Asset and Maintenance management a range of topics need to have priority, e.g. reliability (of planning), availability of resources and installations/equipment, (work)process safety and employee safety, flexibility (to adapt to changing market conditions, competition, etc.). Legal compliancy is another top priority, which should be embedded in legislation, procedures and guidelines. Main benefits to be gained from deploying this model include a clear process analysis, using KPI and trend analysis, thereby enabling a continuous improvement process. Various (IT) methods and tools have been developed to support the analysis. The internet offers a wide range of information on various tools available; also, various knowledge sharing platforms and networking communities can be found. KPI settings in Asset & Maintenance management. Reporting trend reports based on KPI regarding the most important functional areas only has added value if the value measured falls within historical values / boundaries and the goals as © Stichting NAP, Nijkerk 73 set by management. Only then an unbiased analysis, judgement and decision-making can take place. KPI are set selectively for high-level management, in line with strategy and goals. Determining and reporting on Performance indicators deliver the underlying values of the KPI. These are needed to track development on lowel levels and to be able to adjust where necessary. Performance indicators are determined selectively to do analysis on engineering level, including propositions for improvements. Defining too many PI and KPI is not efficient. Priorities are lost and a lot of administrative overhead is introduced. Typically, managers who lack a minimum level of expertise in their area of responsibilities tend to ask too many (K)PI. (Key) Performance indicators make the current and desired situation visible (‘ist’ and ‘soll’). Especially ‘what-if’ questions are important, since they define the impact of new decisionmaking.

The basis for this set op (K)PI is the Balanced Score Card. A correct selection is crucial to keep the right focus; this selection depends on the situation of the company (/site/plant…) and its strategic goals. Many examples can be found in literature. Important note: the value of (K)PI reporting will be gained by following the DMAIC method. Benefits can be transparancy, communication, development & continuous improvement, bottom line results improvements. Various IT systems have been developed to support an efficient (K)PI tracking and reporting. Performance analysis on Costs of maintenance. Maintenance costs are internal and external necessary costs to maintain the functionality of an Asset in line with its design specifications. This includes specifications regarding safety, © Stichting NAP, Nijkerk 74 and technical and functional conditions. Financial conditions can have an important impact, too, e.g. maintenance costs that outweigh the replacement value of an Asset. These considerations can be made at both plant and installation level. Asset Management requires a transparent view on maintenance costs in order to safeguard the ROI of an Asset. In many cases ERP software tools are deployed to support Asset management processes. Maintenance costs are divided into fixed and variable costs. Maintenance should be captured in concepts. Fixed maintenance consists ofpreventive maintenance and an effort driven by legal compliance (e.g. inspections). All this effort can be defined by, and managed via, budgets. The variable part, in many cases corrective maintenance and break-down maintenance, can be influenced and is depending on the technical well-being of the installation. Budgetting these latter costs needs a thorough understanding, knowledge and experience of Asset and Maintenance management to be able to control costs within certain bandwidths. Risk and reliability management are important methods to be deployed. Maintenance cost control demands a good translation of systems, structures and expertise of installations into Maintenance concepts. The result is translated into actions, means, methods and budgets. Annual reviewing and updating is absolutely necessary. Standards are captured and maintained in the Maintenance Report. A thorough Asset and Maintenance Cost Reporting requires good definitions and responsibilities. Continuous attention and continuous improvement programs can realize 1530% reduction of Life Cycle Costs. Asset owners, Maintenance managers and Controllers are main stakeholders and have maximum impact on the performances in this field. The set up of Maintenance Cost report. Maintenance costs should be split up in: Plant Site (buildings, offices, roads) Maintenance costs are reported in € and is the total of: Internal hours x tariff Materials used External costs Excluded from Maintenance costs are: Depreciation of maintenance equipment Costs for product changeover or transaction time (exchange of dies) © Stichting NAP, Nijkerk 75 Downtime costs Definitions of maintenance costs. The following cost drivers are all part of Maintenance costs and the total defines Maintenance Costs: 1) Direct wages for direct maintenance staff (first line maintenance) 2) Slaries for managerial and support maintenance staff 3) Payroll-added costs for maintenance staff (taxes, insurance, legislative contributions) 4) Spares and material for direct use in maintenance 5) Spares purchased for inventory 6) Consumables charged to maintenance 7) Tools and equipment for maintenance purposes 8) Contractor costs 9) Costs for consultancy services in maintenance 10) Administration costs for maintenance 11) Costs for education of maintenance staff 12) Costs for maintenance carried out by production staff 13) Overtime for maintenance staff 14) Costs for transportation, hotels, etc. 15) Costs for documentation, CMMS and planning systems 16) Maintenance of buildings The following cost drivers are excluded from the defintion, i.e. are not considered to be part of Maintenance Costs: 1) 2) 3) 4) 5) Depreciation of maintenance equipment Cost for product changeover or transaction time (Exchange of dies, e.g.) Downtime costs Modifications Improvements or projects External cost: Contractors Hired people In general a relation between maintenance costs and the technical availability of an installation can be identified easily. This interaction can have a positive and a negative effect. The next sections describe an example of each of these. © Stichting NAP, Nijkerk 76 Maintenance costs and availability – a positive effect. The relation between costs and output are not always reported. In this context ‘costs’ means the necessary costs to maintain a reliable and safe operating installation; ‘output’ is return on invested capital (i.e. the installation). However, if impact and risk of any management decision is to be assessed, this relation between costs and output should be clear. In practice, decisions, taken by business management based on cost considerations, not only affect LCC and overall Maintenance costs, but can also have a negative impact on safety and reliability of installations. In worst-case scenarios a ‘License to Operate’ may be jeopardized beacause of lack of maintenance and data control. In this respect it is clear that any managerial decision should be taken based on risk mitigation. A (IT) reporting system and effective set of KPI should be in place to support this decision-making process. Improving Plant availability does not necessarily have to be solved via CAPEX. In many cases an even better result can be achieved by focusing on optimizing work processes. Unfortunately, this opportunithy is not always identified or recognized. The SIG 2x2 OpEx aims to make clear what can be done in this area. Technical Availability & Maintenance Costs 6.0 -2.0 5.0 -4.0 % Availability Improvement % Reduction Maintenance Costs 0.0 % Plant availability -6.0 4.0 -8.0 -10.0 3.0 -12.0 2.0 -14.0 % Cost reduction -16.0 1.0 -18.0 0.0 -20.0 Start Year 1 2 3 4 5 2 The figure above shows the relation between Maintenance Costs and availability. The effect of the input needed to take the technical availability of an installation to a next level is made visible quite clearly. The figure also shows that costs will decrease only after this has been accomplished; this can be seen as an investment in improving maintenance work processes. This real-live case was executed without any CAPEX. © Stichting NAP, Nijkerk 77 Considerations Although Maintenance costs represent only a fraction of RV, they can have a huge impact on output. As an additional benefit, a thorough understanding of this dynamics at highest management level contributes to reliability and competetive advantage of the entire company. Lastly, a well-functioning management of installations, availability of effective IT (ERP) systems and competence of staff are all conditions to succes. Maintenance costs and availaibility – a negative effect. A good design using the right equipment and materials leads to minimal operational and maintenance costs. Related costs, resulting from malfunctions and corrective actions to be taken will be lower. The theory is correct providing the right budgetary actions are taken. In practice however, other factors have a big impact, too: besides a good design and business model, it is of the utmost importance to have a good maintenance concept and risk management model in place. This is also important from a sustainability perspective: less costs of losses, less operational costs, improved safety and reliability, etc. The risk management model should be support by (IT) systems capturing plans, procedures, inspection regimes, spare parts positions, reports, replacement policies, etc. It goes without saying that a competent organisation is the basis for all the above. Too often Technical Services organisations do not meet the demands as described above. As a consequence, maintenance budgets are not based on good risk management and concepts, but rather determined by financial considerations. This may have disastreus consequences for safety and reliability. The basis for a good risk management is for Technical Services organisations to be able to have Maintenance budgets and plans based on a fixed (compliance) part and a variable part. The fixed part takes into account the compliance to government legislation, owner, vendor, etc.; the variable part should be able to handle unexpected, non-budgeted disruptions. If these conditions are not met, budgets may be cut in difficult market conditions without a proper guidance from the responsible management. The figure below (trend report) shows a case where even customer delivery reliability was at stake, as was the Licence to Operate. © Stichting NAP, Nijkerk 78 This picture shows the effect of short-term policy and lack of vision on Maintenance. Note that the Maintenance costs doubled (!) because of the backlog in maintenance activities and the way the site was perceived severely deteriorated. Best practices from Asset and Maintenance management. The team Asset & Maintenance management of the SIG 2x2 OpEx has developed 5 cases, or best practices. They can be divided into: Best practice example on deploying technology: 3D laser scanning Best practices regarding the organisation of the maintenance management function: o Outsourcing maintenance o Asset integrity & maintenance management Best practices related to methods and techniques: o Value Engineering o Asset management Excellence © Stichting NAP, Nijkerk 79 Best practice: 3D laser scanning in Operations and Maintenance of process installations. What is 3D laser scanning? The 3D-Laser scanning (3DLS) technique is deployed more and more in many areas. This technique makes it possible to describe existing situation in detail. A scanner is a measuring instrument, the measurement is done via a laser beam. The scanned environment is transferred into pixels – small dots representing reflections. The result is a ‘cloud’ of pixels of tens of millions of pixels, each defined by a 3D (X, Y and Z) reflection value. This 3D ‘pixel cloud’ serves as a basis for 3D reconstruction, e.g. in a CAD tool. Applying laser scanning in engineering The technique of mapping existing environments using 3DLS has developed strongly in the chemical and petro-chemical industry. In general experiences using this scanning and measuring technique are positive, bringing a high accuracy, completeness, quick (data) processing, multi-usability, conversion options, compatible with many 3D engineering SW tools, and broad applicability during all phases of an installation’s life cycle, from feasability study to decommissioning / demolition. Laser scanning techniques have been part of the package of Virtual Design & Construction (VDC) for a long time. As an example the deployment in the I-room is considered (see picture below), where the laser scan acts as a visual tool to describe the existing situation and environment during the design and engineering process. Laser scanning in Virtual Design & Construction (source: Royal HaskoningDHV) © Stichting NAP, Nijkerk 80 Industry example of laser scanning and 3D-CAD modelling Especially at upgrade, revamp and modification projects of existing installations (brownfield engineering) 3DLS proves to be a powerfull aid to implement new equipment seamlessly in the existing environment. 3D models are often converted to 3D-CAD applications, for the engineer to determine adjustments and connections very precise. Issues with sizing and usage of space when introducing new components can now be solved during the engineering phase already. Research by Spar Point Research2 indicates that in Brown field projects cost reductions of 57% have been realized on the total installation costs, plus up to 10% in time savings. The latter is especially interesting for continuous processes, where every day of production loss counts heavily. In these situations the investments needed to perform the 3D scanning are only a fraction of the savings that can be realized. 3D laser scanning in Operations and Maintenance 3D Laser scanning also proved its value at installations already in use. 3DLS makes enables a visualisation of the existing situation to be used for: Legal obligations: updating documentation in Piping & Instrumentation Diagrams (P&IDs) Enhance safety: use visualisation of installations with limited access (e.g. closed confinements, dangerous locations (radio-active, emissions, etc.)) Instructions and work preparations : staff can be instructed / informed about the work location via visualisations, instead of being at the location physically 2 3D Laser Scanning: Benefits and Paysbacks for Industrial Plant Design, Construction and Operation, Spar Point Research, 2009 © Stichting NAP, Nijkerk 81 Royal HaskoningDHV has developed an Asset Support Tool for Maintenance & Operations support. Originally this tool was developed to support Plant Stops. Besides the normal ‘critical paths’, logistics and integration of projects are main determinators to a successfull and efficient Plant Stop. In most cases only procss-related interdependencies are considered when determining the traditional critical paths. Geographic and/or logistic interdependencies are often not taken into account. Various tools and other aids are available on the market to support the preparation and execution teams during this task. The Asset Support Tool is mainly used to support the work preparation, but can be deployed in many other ways and in other areas, too. Asset Support Tool as developed by Royal HaskoningDHV This tool combines 2D and 3D data together; using an interface all this data is presented as one to the end user. In this way it can visualize maintenance-relevant information using 3D in an easy to understand and geographically correct way. The tool combines data from different sources: 3D CAD models 3D laser scan data of the entire installation or entire plant A maintenance database, e.g. Ultimo or SAP-PM, including all data of stop-related activities such as stop point number, description of work / task, geographical location, functional location, logistic dependencies, contractor(s) involved, etc. © Stichting NAP, Nijkerk 82 2D drawings (plot layout) Avatars: simple 3D objects identified by a unique number, identical to the unique stop point number in the maintenance database (also including the geographical location in the plant). Using a navigation interface, the user can ‘walk through’ his own plant. Avatars are easy to recognize and contain a link to the maintenance database; they are also linked to (e.g.) an execution planning. In this way all activities for a plant can be planned more efficient and any ocurring logistical issues are identified on time. The progress of the planned stop can be made visible dynamically through simulation. Additional advantages include : More efficient planning of activities, e.g. using 4D simulation Identifying and solving logistical issues quickly and in a structured way Improved geographical overview Shorter stop Less investment costs. Best practice: outsourcing as cost saving. In the Process Industry, cost savings are often found in organizing yourself ‘lean and mean’. Most production organisations have very similar structures. A plant (or site) manager is responsible for a number of departments or units, usually Operations, Maintenance and Projects. The plant manager is supported by staff teams like Purchasing, Finance and HRM. Within these supporting functions all kinds of activities take place which can be ranked in order of significance of contributing to the primary process of the production plant (which is: producing at maximum margin). Benefits are determined by the market (sales dept.), costs are determined by the production assets. As a rule of thumb manufacturing companies tend to focus primarily on the production processes and less on the non-core assets. Maintenance and Operations is organised to make the primary production process as efficient as possible. Supporting assets such as civil constructions in plants get less attention, unless (of course) ‘License to Operate’ or Safety may become an issue. Maintenance of core assets is not considered for outsourcing; the maintenance of non-core assets might be considered to be outsourced. © Stichting NAP, Nijkerk 83 Process Civil structures Surrounding infra & buildings Non-core assets Non-core assets are considered to be those parts of a company that are not primarily essential to the business and to create revenu, cash flow and profit. This does not mean that non-core assets do not represent any value – on the contrary. When creating these assets, an investment was made because they add value to an undisturbed primary (production) process. It is the asset owner’s interest to maintain this value. Outsourcing “Outsourcing’ has been around for decades and is defined as: the execution of a strategic decision to redeploy its own personnel, organisation assets and/or invested capital for the execution of supporting processes to a 3rd (external) party. The organisation that is outsourcing work will contract an external services provider or vendor to execute the tasks to be outsourced. Preferably an external provider is chosen whose core competence is in the area of the work to be outsourced. Many examples of outsourcing can be found in catering, security, cleaning & facility © Stichting NAP, Nijkerk 84 management, maintenance, ICT, car park, payroll / HR services, warehousing & distribution (raw materials, (semi-)finished goods), marketing, callcenter (complaint handling, after-sales services), finance and accounting, etc. As an example from the process industry, DSM has been outsourcing its ICT since 1992, although this evolves, too. Today, DSM is working on the 3rd generation outsourcing. Another example is Philips, who has been transferring various company (business) units to different countries. IT services are mostly outsourced to low-price (low personnel cost) countries like India. An engineering services company like Royal HaskoningDHV has been outsourcing in this way, too. Dividing core and non-core – an arbitrary choice The process industry finds cost savings primarily by minimizing necessary costs to maintain non-core assets. The question that rises is, what is a non-core asset and what is a core asset? The answer is not easy to give. For example, building / construction and air conditioning are key to a company that depends on cleanroom conditions; however, for a bulk chemicals plant buildings will be key to be usable as control room, or office room, i.e. less important for the quality of the product out of the primary process. Example of assessing outsourcing feasibility AkzoNobel uses an interesting method to assess feasibility to outsource (or not). Various site services can be defined for every production site (see figure below): © Stichting NAP, Nijkerk 85 Site Service Portfolio Engineering Inspection Controlling & Planning Warehousing Laboratories Accounting ProcessTechnology Purchasing & Contract Management Human Recourses Operations Environment & Permitting PR & Communication Maintenance Management Q-Systems Project Management Logistics Health EMRES Fire brigade 1st Line Maintenance Safety Security Maintenance & Construction Citizenship Facility Management Plants Shared Services Competence Team Outsourced These services can be ranked according to the principle of commercial availability and business impact. Services with a high business impact and low availability will – in general – be very site- or plant-specific, and will therefore be part of the site’s or plant’s core activities (see figure below).

Since 2006, ASITO, an external facility services provider, has been taking care of facility services; Royal HaskoningDHV has been the services provider for DSM for the maintenance and operations of the on-site infrastructure. Outsourcing of activities to a 3rd party whose core competence is the maintenance of noncore assets has been proven valuable. Savings have been realized by (among others) efficiency measures, economy of scale advantages and making specific knowledge and expertise available. All activities are measured via KPIs, quality levels and service level agreements. In terms of costs, savings of 10-20% have been realized. PAS55 / ISO 55000: the next step in professionalizing asset management Cost savings can only be realized up to a certain level. Asset management is about finding the balance between performance, risks and costs of assets during the entire life cycle, in accordance with the PAS55 / ISO 55000 management system. © Stichting NAP, Nijkerk 87 ASSET OWNER The PAS55 system contributes to the transparancy in the roles of asset owner, asset Targets manager and service provider. Deming’s PlanPerformance Do-Check-Act cycle is encompassed in this Progress system, contributing coninuously to improving Planning asset performance. This way cost ASSET SERVICE optimalisations can be made ánd at the same MANAGER PROVIDER time managing risks to an acceptable level. Such a system will not contribute to cost savings in itself ; however, it will help prevent unforeseen costs, and possibly even legal consequences, related to maintenance activities. Systems like this prove valuable from the level of corrective maintenance / ‘fighting fires’ up to the level of integrated asset management and preventive maintenance. Best practice on Asset integrity and maintenance management. Among the responsibilities of Installation (asset ) management and Maintenance management, managing the integrity and safety of any installation are among the most important ones. Without these, it is impossible to adher to the demands related to License to Operate. This requires from management the ability to develop a vision, strategies and concepts and have them deployed and evaluated structurally. If policies are not based on the above, the consequences can be desastreus. © Stichting NAP, Nijkerk 88 The picture above shows the result of a lack of good maintenance, ad-hoc budgeting activities and – maybe the most important one – underestimating the required knowledge, expertise and level of involvement of personnel. Day-to-day reality shows that too often the human factor is neglected under the pressure of performance, efficiency and cost reductions. As a typical trend, modern management tends to try and eliminate disturbances by using (mandatory) procedures and trainings. As a result, personnel is less involved and feels out of balance: the opposite of what is intended is achieved. Good people management should be able to improve matters, here. Today’s society also has a tendency to ask employees to take more responsibility. Based on the premise that people learn from their mistakes, it is expected that a self-learning, selfimproving culture will develop and, at the end of the day, results will improve. In practice, however, quite the opposite is happening. Driven by an increase in (safety) procedures, guidelines and having to report back to higher management, staff tends to delegate his or her own responsibilities to others. This behaviour has a negative effect on overall attitude and behaviour. One should always consider that any formal organisation can only function well if the informal organisation is appreciated and valued! In this perspective it is worthwhile to note that recently Stichting NAP has taken the initiative to set up a Code of Conduct. This code should support individual professionals and managers in showing their commitment and take responsibility regarding process safety and technical integrity of installations and assets in general. © Stichting NAP, Nijkerk 89 Best practice in Value Engineering. 10 years ago, Value Improving practices and ICT tooling were already suggested. Collaborative engineering already described Life Cycle Engineering and the commitment and involvement of all stakeholders, including Maintenance, in the engineering process. Predictive maintenance was also mentioned as a Value Improving Practice : upfront taking into account the operations & maintenance phase of an installation, and the development of long-term maintenance models in collaboration with Engineering, including the necessary monitoring activities. The NAP publication on Front End Loading strategies (2008) brings a new perspective on the importance of a good Project Engineering strategy (introducing the FEL matrix). A few years later newer Project Engineering techniques are reported such as various project management tools and engineering tools. Here, too, we see the importance of CAPEX decisions versus a plant’s long-term operations and OPEX (Plant life cycle costs). Nowadays Value Engineering is common practice in several sectors, e.g. in infrastructure. An organization like Rijkswaterstaat demands this for her projects. Thinking about the relationship between functions and costs. RHDHV uses her experiences with System Engineering to make Value Engineering a success. System Engineering uses a life cycle approach (life cycle costing), a multi-disciplinary approach and structured information management. SE also means attention for stakeholders, working top-down and controlling the interaction between technology and other functions in a project. It’s very important to put design choices (and costs) in the perspective of the phase of using objects. As an extra aid an interactive design process is deployed when using Value Engineering. Advanced techniques for interactive 3D design, risk control and information management can be deployed. Alternative scenarios can be developed and checked against usability, in collaboration with advisors from specific areas of expertise. © Stichting NAP, Nijkerk 90 These types of design processes are very rare in the (process) industry markets. When running an industrial project, there is always the risk of design processes being squeezed into the project’s (tight) time frames. The project’s main interest is in managing risks, and complying to (time) planning and costs, i.e. short-term interests. The methods as described in the 2002 NAP publication are hardly used. A lot of profit can be gained here. This publication gives another view on the design and engineering process and the relation with OPEX: The view of the reliability engineer. Best practice in Asset & Maintenance & Life Cycle Costs. When developing ‘projects’ the consequences of choices for an optimal (LCC) management, costs and output, need to be evaluated sufficiently. If not, the additional costs (direct and indirect) can have a negative impact on the operational management of installations and facilities. Functional integrity, delivery reliability to customers, and compliance to safety standards can even be compromised. The value of Reliability Based Engineering. In maintenance there is a significant difference between maintenance engineering and reliability engineering. This difference can also be characterized as re-active versus proactive. In some cases the consequences of choices regarding an optimal (LCC) management, costs © Stichting NAP, Nijkerk 91 and output are insufficiently considered, during the setup of projects. The recurring costs (both direct and indirect) may have a large impact on the operational maintenance of buildings and installations. The reliability of installations and functionality can be compromised. As a result, delivery reliability to customers and safety may need for extra attention. Giving insufficient attention to the above will lead to reactive (unplanned) maintenance, the need for extra warehouses, unreliable installations, redundancy and increasing labour costs. To prevent dissatisfied customers quite often a lot of effort is requested from the second-tolast step in the SCM chain. Maintenance engineering is often deployed reactively to establish structural improvements. Pro-active Reliability Engineering pevents this! The development of Maintenance concepts is one of the primary responsibilities of a Maintenance Engineer. However, in general the ME spends the majority of his time on improvements afterwards. Asset management focuses on the prevention of, and the preventive actions regarding potential malfunctions. In other words, when striving for Maintenance Excellence the goal should be to have zero disruptions, thereby meeting the standards of safety, availability and reliability. The function of the Reliability Engineer aims to optimize a (new) installation’s performance upfront, in terms of sustainability, reliability and safety. One of the goals of this function is to avoid maintenance, in the context of Asset management. Performances can be improved by 10-30%. Both functions aim to lower operational costs and comply to SIG 2x2. Conditions to best Asset & Maintenance & LCC. Based on day-to-day practice, a number of conditions can be identified leading to Best Asset and Maintenance management and strive for A&M Excellence. This listing is a summary of best practices at various companies : Organize functions: knowledge, planning & scheduling, execution Develop vision, strategies and concepts for Asset & Maintenance mgt. Give priority to HR: Competences, expertise and attitude, engagement Give priority to info/ data management at all layers needs for reporting © Stichting NAP, Nijkerk 92 Set up Performance management: select right KPI and PI Manage Top X topics for priority setting and lean management Install TPM and Lean methods for selecting Added value and OpEx Develop culture of Continuous Improvement ‘driving’ sustainable results Develop excellent Communication/ Reporting, for evaluation & follow up Important: safeguard balance in finance, process, innovation & customer Never forget all results are the output of people, your colleagues!

Within the context of these building blocks reliability centered mainentenance (RCM) has an important position. The figure below shows the RCM approach, making cost and performance drivers visible. © Stichting NAP, Nijkerk 93 This facilitates improvement management to focus on the most relevant topics. Plant performance killers MC/CRV % Maintenance “cost drivers” AVG MC/RV% Dryer General LESS LOSSES: LOWER COST Cooler Filter 3% AVG MC/CRV % IND F IND ALG Pump NEUTRAL LINE MENGW Compressor 4,5% “downtime (hrs x cost) killers” The human factor – leadership versus management. At the end of the day, it is (individual) people who make a difference. For Asset and Maintenance excellence this is applicable too, the same as for any other functional or professional area. This alone already justifies why special attention should be given to people and the way they collaborate, learn and improve. It takes excellent management to optimize work processes in terms of effectiveness and efficiency (striving for perfection); it takes leadership to take a leap forward as an organization to a completely next level of maturity (striving for excellence). Leadership and management are two different capabilities. The ideal organisation, and team, will have leaders and managers in an effective and efficient mix at work. Some of the features of leaders and managers, i.e. the differences between the two, are depicted in the table below. Leaders Vision, innovation, flexible Entrepeneurship © Stichting NAP, Nijkerk Managers Control, less flexibility Procedures, striving to ‘best-in-class’ 94 Effectiveness, unique Mission, strategy & goals Delegation, development Continuous improvement Conceptual management Few KPI and trends Encouraging empowerment Responsible care Creation develop ownership Clear course Efficiency, compete Manage on targets, figures Supervision on agreements Project management Micro management Many KPI, passive styles Desire to be in the lead Eleminating risks Demolishes ownership Bureaucracy controlled Typically, time effectiveness of people in your organization can be depicted as in the graph below: The key learning from this graph is: When investing in people management, i.e. striving for (people) excellence, it will be your staff themselves who will start minimizing the ‘time theft’ gap! People will be more involved, better equiped, have a better understanding on what to do in which circumstance, etc. if the organization they work for continuously invests in people skills and collaboration across organizational borders. © Stichting NAP, Nijkerk 95 Part 3 : Turnaround management. General introduction. The first and simple question to ask ourselves when looking at turnaround management in the process industry is: “Why do we have turn-arounds?”. Reasons vary: Legislation (e.g. stoomwezen) Large maintenance: replacements, repairs Pitstop maintenance: inspections, cleaning Plant upgrades Unplanned (circumstantial) maintenance Economic reasons: no demand For turn-around in the (chemical) process industry, the 2x2 OpEx goals translate as follows: Cutting the operational costs by half: Make the installation fit for purpose and execute plant upgrades via CAPEX investments. Extend the life time by a factor 2: decide on, and deploy, an optimal interval planning. Facts and figures Some facts and figures in order to put the importance of turnaround (management) into perspective: In Europe € 3 billion is spent on turn-arounds annually Indirect costs outnumber the direct Turn-around costs 2/3rd of contractors has been replaced over the last 5 years 18% uses an outsourced planning Trends Many trends can be identified relating to developments in Turn-around management: Responsibilites Interval planning Outsourcing Planning – scheduling CAPEX Organization Communication Scope definition Knowledge management (improvement process) © Stichting NAP, Nijkerk 96 Acknowledgements. The following persons contributed on the topic of Turn-around for the SIG 2x2 OpEx of NAP: Paul van de Lisdonk (Aquilex) Bart van der Meulen (Tata Steel) Pier-Jan Hettema (Tebodin) Albert Snippe (Vattenfall) The methodology of turnaround management. Turnaround, also known as maintenance shutdown or outage, is a repetitive planed interruption of plant operations in order to perform general inspection, reparation and improvement. To reduce the costs due to the loss of production, turnarounds are always performed as detailed planned projects with a very tight schedule. Therefore a turnaround can be divided into different phases: Phase 1: Preliminary planning Detailed planning and a well-organized schedule are the basis for the success of a shutdown. Therefore most of the time is invested in these phases. Depending on the size of the plant and the complexity of the included processes, a shutdown can easily take more than a year time of planning. In the first Phase the scope, the operations and the periphery are planned on the basis of the specific requirements of the plant. The result of this phase should be documents, ready to be tendered and a general schedule containing the basic frame conditions and considering all regulations and recommended practices. Phase 2: Planning of shutdown execution Based on the general planning in Phase 1 and the generated documents, the scheduling and resource planning can take place. Therefore the elaboration of operation charts and workflows is the primary goal. The result of this phase should be the complete plan of the turnover including… Phase 3: Decommissioning of plant As the name “shutdown” already indicates, the decommissioning of the plant is inevitable in order to deliver a good and consistent turnaround. In this phase all processes that are in contact to equipment that has to be examined are stopped and the process lines that contain dangerous substances have to be scavenged. Phase 4: Execution of Operations After the decommissioning, the plant is prepared for all actions planned in Phase 1 and 2. Therefore all actions have to be carried out as described in the plans, workflows and schedules. Transparent information channels and regular meetings of the responsible © Stichting NAP, Nijkerk 97 personnel shall guarantee early detection of delays and bottlenecks resulting in a strict adherence to the overall schedule. Phase 5: Recommissioning Following the fulfillment off all shutdown activities given in the plans and schedules, the plant has to be reassembled in order to restart the processes which have been stopped during the turnover. It is crucial to the safety of the plant and its personnel alike the success of the shutdown, that all work that has been done to this point was carried out completely, accurate and under consideration of all given guidelines. If all of these requirements have been fulfilled, the plant should be recommissioned without major problems and afterwards be working well. It has to be taken into account that especially plants with complex and time consuming processes will not reach full capacity in a short period of time. This has to be considered during the scheduling and planning of the shutdown. Phase 6: Review After completion of a turnaround, it is fundamental for the success of future shutdowns to have an extensive review on the factors of success and failure that occurred during this project and to document potential processes to eliminate failures and strengthen success. Only a documented review will offer the possibility of continuous improvement and prevention off repetitive failure. Reasons for a turnaround. Though the procedures done in a shutdown are in most cases very similar and just differ in the details, the reasons for a shutdown can be quite different. The most common turnaround is the inspection shutdown, having the aim of investigate condition of the plant and taking actions to bring it into a condition that fulfills all internal and external regulations. If the plant is expected to be brought back into immaculate condition, the turnaround is called an overhaul shutdown, in which all equipment not fitting the conditions is exchanged. Occasionally, a turnaround is not just aiming for the removal of degradation due to the aging of the plant but also for the improvement of the containing processes. These improvement shutdowns are very often combined with overhaul shutdowns. The types of turnarounds mentioned above all belong to the group of planned shutdowns. Though these types of turnarounds in most cases are preferable due to the possibility of the definition of the scope and the estimation of the costs, there is always the possibility of an emergency shutdown. Such an unplanned shutdown is necessary when a high risk is determined in the plant so that the safety of the personnel, plant or surrounding cannot be guaranteed. © Stichting NAP, Nijkerk 98 Modern challenges and chances by performing turnarounds. Nowadays turnarounds at industrial companies receive more and more attention and are ranked higher on priority lists. One of the reasons for this development is the increasing amount of laws and regulations forcing companies to reassess their turnaround management to ensure the safety and sustainability of their equipment but also the awareness of increasing investment costs for new plants that can be reduced by keeping the old plant in a good condition and adjusting them to the changing parameters that might have occurred during its lifetime. One of the main advantages of regular turnarounds is the possibility to plan and schedule the shutdown upfront. This ensures very short downtimes and high reliability by preventing unplanned emergency shutdowns. Though the loss of capital might be little higher while performing turnarounds, the costs are easy to estimate and therefore the risks of unplanned loss of production can be massively reduced. In light of the above description of Turnaround developments 4 best practices are described : DuPont, Tata Steel, Shell Global Services and Bilfinger. These companies are faced with turnarounds regularly and are handling them effectively, from different points-ofview. © Stichting NAP, Nijkerk 99 Business case #1: DuPont. Introduction to DuPont. Du Pont de Nemours (Nederland) B.V. is part of the global E. I. Du Pont de Nemours and Company, a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation. The DuPont sites in the Netherlands are situated in Dordrecht, Breda and Landgraaf. DuPont Netherlands employs approximately 950 people. Dordrecht is one of the largest production sites of DuPont in Europe and it is the company’s eldest site in the Netherlands. The site is home to nine manufacturing plants where the synthetic resins Delrin® and Surlyn® are made, the refrigerants Isceon® and Suva® and the fluoroproducts Teflon® and Viton®. The Teodur Powder Coatings sales organisation and the DuPont Crop Protection marketing organisation are located in Dordrecht as well. The sales organisation of Standox® automotive refinishing paints is located in Breda. The Landgraaf site manufactures filaments for the toothbrush industry. All production sites of DuPont in the Netherlands are certified according to ISO-9001 and ISO 14001. A summary of this business case can be found in Annex 4. Turnaround management at DuPont. DuPont Dordrecht is planning and performing their shutdown independently from shutdown activities in the nearby areas such as the Botlek. They are not taking into account the shutdown planning and possible (non-)availability of contractors due to Botlek and Europoort schedules. The site consists of two Strategic Business Units (SBU). All Inspection planning and scheduling is being done by the same site team, performing the shutdowns on both SBU´s not simultaneously. This section describes the best practices that enables DuPont to successfully perform turnarounds. © Stichting NAP, Nijkerk 100 Scheduling DuPont is using Oracles EPPM solution Primavera as the central tool for scheduling shutdowns. Therefor all procedures planned for the turnaround are scheduled in one Primavera schedule, allowing a detailed summary on all tasks to be dealt with. To ensure that no tasks are being overlooked, the software offers a variety of filters, to provide the user with the overview he or she needs. DuPont is using the following freezing dates: Capital freezing date is one year before the turnaround starts Maintenance/Production freezing date is five months before the turnaround starts All add-ons to the shutdown need to be approved by the site Turnaround Steering Team. DuPont defines the following fixed Milestones for each turnaround: End of wrench time (hands-on) End of commissioning Ramp up time (sustain date) The Scope is always scheduled without contingency by the units in order to plan the pure work. Contingency is put in by the site scheduler afterwards. Capital An important issue during a recent turnaround organisation schedule was the fact that the approval for capital expenditure was too late. As a result, the purchasing of equipment was delayed and equipment was not ready for the turnaround period. This has to be taken into account in future turnarounds. Intervals There is a limit in the complexity DuPont wants to handle during a turnaround period. This is the main reason for not extending the turnaround intervals. DuPont’s philosophy is to do smaller intervals with less complexity rather than bigger intervals with big complexity and risk. Continuous Improvement Process (CIP) Over the last turnaround periods DuPont spent a lot of time in analysing the root causes of the turnaround issues by RCA methodology. More than 200 recommendations were identified and monitored and as to date, only 7 recommendations are open. The turnaround organisation is a corporate competence with an assigned Corporate Turnaround Manager. At three stages in the Turnaround cycle corporate 2 nd party audits are held to audit the process: © Stichting NAP, Nijkerk 101 audit focus of the turnaround organisation audit focus of the turnaround schedule audit focus of the complete turnaround preparation and execution (all) The audit consists of 93 questions that will lead to a score from 0-100%. The score is used for internal benchmarking and reporting. Organisation and Communication Responsibilities in the Turnaround organisation are designated to business level. The site Turnaround Team starts with issuing a Business Objective Letter. If there is a change in the objective, a revision of the letter is issued and is communicated on all levels On site, different expert teams are performing the assigned tasks Steering Team Core Team per business unit HSE-Team Scheduling Team Scope At DuPont, the scope of the turnaround is defined by: Maintenance: 60% of the data is coming out of SAP (PM) Technical/Engineering Production Inspection reports of equipment are all set up, maintained and stored in SAP completely. Depending on the scope, items are skipped out. So inspections are always starting from a complete inspection scope. Business case #2: Tata Steel. Introduction to Tata Steel Tata steel IJmuiden is a top steel producer in Europe, with high quality products and a complete product range of steel products and related services. The steel products from IJmuiden are mainly processed in construction, in lifting & excavating machines, in consumer goods such as white goods (refrigerators and stoves) and in the automotive and packaging industries. The site has excellent logistics based on its location and the deep-sea port, railway, road and inland waterways; it holds an excellent export position and home market with high-value markets. Health and safety is Tata Steel’s number one priority. In IJmuiden, Tata Steel runs a fully integrated production process, ranging from iron and steel making, to rolling and coating, with a tradition of innovation and continuous © Stichting NAP, Nijkerk 102 improvement. The site’s production capacity is 7.5 million tons of steel. Approximately 9.300 employees, including 250 researchers are employed in IJmuiden. A summary of this business case can be found in Annex 5. Shut downs at Tata Steel. Tata Steel in IJmuiden is organised in 10 Works and 3 Service Units. In total there are around 60 facilities. These facilities differ very much in size and shut down regime: from pit stops of 4 hours each week to large scale shutdowns of 3 months after more than 10 years continuously in operation. To manage these various types of stops a classification system is in place to apply different sets of working procedures for different types of shut downs, to be able to manage the shutdown properly. The execution of shut downs is the responsibility of the Works, including scoping and scheduling.The Central Engineering department has set up standards for shut down management to improve the execution. Apart from setting shut down standards, this department is also responsible for quality reviews during the preparation phase and overall site scheduling. Although standard procedures as scope freeze and schedule freeze are well known parts of shut down management, these procedures have to be tailored to different types of shut downs. At this moment Tata has decided to use a simple approach in which scope freeze and planning freeze dates are set by the following rules: © Stichting NAP, Nijkerk 103 Level of complexity is set by two rules: • length of stop: – – – < 24 hours 24 – 96 hours > 96 hours OR • simultaneousness with other stops: – – – 0 1 >1 Outcome: – – – Low Medium High The level of complexity defines the timing and organisation of the shut down: Complexity • Low • Medium • High Scope Planning freese freese (weeks)(weeks) 4 1 7 2 10 2 For mayor Blast Furnace shut down (1/10 years, 3 month duration) a separate organisation is set up. As shown in the figure, two variables are considered: the duration of the stop and the simultaneousness with other stops. For example, if the steel plant has a regular maintenance stop, the blast furnace has a stop as well due to the fact that hot iron production is coupled to the steel making process. In this example the shut down complexity is higher, having more contractors on site and more complicated logistics to be managed. As depicted in the figure, a higher level of complexity will ask for more preparation time and therefore, scope freeze and planning freeze dates are set earlier. The use of standardized codes of status of work order preparation, like order ready for scheduling of ready for execution, enables the monitoring of preparation progress compared to the different scope and planning freeze dates. All this information is available in our Maintenance ERP system. This increased transparency has improved the quality of preparation significantly. Trends and issues. One of the major trends is increasing shut down intervals. There are several facilities working with intervals between 4 to 10 weeks. Increasing the interval will result in more uptime and less logistic disturbances. A decrease of experience of shut down management is not to be expected because of the relative short intervals. Another important trend is the increase of foreign personnel. Cultural differences, language © Stichting NAP, Nijkerk 104 barriers and communication issues are likely to increase the risk on health and safety issues. A third significant trend is to uniformly apply methods (standards), to professionalize shut down management. Part of these methods is more focused on risks / risk management (e.g. quality review, scoping). CAPEX projects in plant shutdowns introduce high risks since shutdown- and project management are not synchronized. High peak loads for contractor personnel introduce the challenge to ensure quality and low costs (HoTT). Lastly, due to the extreme long interval period of 14 years for the Blast Furnaces, it proves difficult to maintain the specific turnaround knowledge and have it available on-time. Business case #3: Shell Global Solutions. Introduction to Shell Shell Global Solutions (SGS) helps improve its customers' business performance by providing leading-edge energy consulting and innovative technology. SGS is committed to responsible energy, innovative technology solutions and environmentally friendly approaches. The technologies provided by SGS have been developed in response to the challenges that emerge when operating complex process plants in demanding operating environments. SGS has its origins in the research and technical service organization that supported the Shell's activities worldwide. Originally, their mandate was to work with the Shell businesses in the development of “wellhead-to-wheels” technology. However, it was recognized that their leading-edge technologies, intellectual property and operational expertise could be a significant value creation opportunity for other leading players in the industry. By drawing on its experience, SGS provides business and operational support including project-execution services from design and engineering through ommissioning and start-up, experience transfer, master planning and training. A summary of this business case can be found in Annex 6. Turnaround management at Shell. Shell has their biggest refinery at Pernis in Rotterdam, producing around 400.000 barrels/day and a chemical plant in Moerdijk. The Turnaround policy is based on deploying dedicated Turnaround teams with the assistance of very experienced turnaround consultants that support shutdowns performed worldwide. © Stichting NAP, Nijkerk 105 The collected best practices of the Shell Global Solutions B.V. are listed below. Scope The central aim is always to stay responsible for the scoping, to minimize possible risks. In fact, every workorder in a turnaround can be carried out by external contractors, except for the scoping. The scoping personnel has to be highly experienced coordinating turnarounds, otherwise you will be losing control. Shell is planning their turnaround strategy from a risk based point of view. Depending on size and nature of the plant considered for a turnaround, the strategy can be chosen, as long as the primary goal is reached to make the installation fit for purpose for the next running interval, guaranteeing optimal operation and a high reliability of a plant. Organisation and Communication Agreements between refineries about turnaround intervals and shutdown times are not permitted by European law. Using long term contracts with the main contractors which are not bound by this law, this kind of information can be shared informally. The second advantage of long term contracts is the improvement of the Turnaround Teams working together, which is crucial for the success of a project. Continuous Improvement Process (CIP) The assignment of a worldwide competence team, i.e. SGS, with in-depth knowledge supports the Continuous Improvement Process. In addition, long term contracts support the continuous improvement and gain of knowledge on the plants themselves. Intervals The intervals for a shutdown are very depending on size and complexity of assets. From a HSE (Health, Safety and Environment) point of view it is preferred to have less people on site, therefore shorter intervals with a clearly laid out scope are often better than long intervals with a big scope and more contractors on site. Capital Total Cost of Ownership mostly comes out of Capex resources. The lifetime costs are not always taken into account totally. Scheduling Shell prefers the springtime for big turnarounds because it offers the best weather conditions. © Stichting NAP, Nijkerk 106 Business case #4: Bilfinger. Introduction to Bilfinger. Bilfinger Industrial Services supports its customers with the (turnaround) expertise it has acquired over many years, which it makes available to them within an international network. When it comes to turnarounds, Bilfinger Industrial Services is a competent partner to the industry. Its expertise in maintenance as well as construction and project business represents the foundations for professional handling of challenging turnarounds. Numerous references for successfully implemented turnaround projects bear testimony to this. Planned maintenance activities, such as major repairs and turnaround projects, have a substantial impact on the operating result of a technical facility. Against the backdrop of mounting competitive pressure, professional turnaround management is therefore becoming an increasingly critical success factor for manufacturing companies in all industry segments. The integration of revamp projects into a turnaround represents a particularly challenging task relating to project planning and handling. By intertwining the turnaround business with the maintenance and project organization within Bilfinger Industrial Services, the company is ideally prepared for this assignment. Thanks to its wide portfolio, Bilfinger Industrial Services is in a position to realize both partial services and turnarounds as unit or general contractors. Budgets and adherence to time schedules are key focal points of each turnaround. At the same time, high safety and quality standards must be ensured. This is possible by deploying a consistent and solution-oriented project management system comprising planning, coordination and execution on the one hand as well as analyses and sustainable documentation on the other. For Bilfinger Industrial Services, this is the model of the future. Not only does it have extensive experience and know-how, but also an organization that is geared towards implementing newly discovered findings in the context of methodological skills and standardized processes, without neglecting the required flexibility. A summary of this business case can be found in Annex 7. Outsourcing Turnaround management. Bilfinger is a partner for companies who don’t have a big enough organisation or don’t have a corporate competence organisation to handle a big 4-5 year turnaround organisation and schedule. In this business case a big refinery in the Europoort area of Rotterdam is one of the clients of © Stichting NAP, Nijkerk 107 Bilfinger. The refinery has a 5 year turnaround schedule and Bilfinger organises the turnaround management this year (2013) for the 2nd time. The Bilfinger organisation is at peak level, during the Turnaround execution phase at a level of 120 FTE’s. During the planning phase the organisation starts at approx. 50 FTE’s. The refinery uses also Bilfinger as one Turnaround partner, so all subcontractors are contracted by Bilfinger purchase department. Although there is one Turnaround partner, the scope of the turnaround is managed by the Client. The Bilfinger Turnaround organisation is depicted in the figure below: © Stichting NAP, Nijkerk 108 There are two phases for Bilfinger, a Planning phase and Execution phase. The planning phase is characterized by the following activities: Scope by Client, scope is frozen appox. 6 months before turnaround. Data collection Site checks Scope to work packages Scheduling Bilfinger’s responsibilities include, but are not limited to: QOHSE Cost (unit rates) Extra work (approval by Client) Delivering a pool of FTE’s for flex force Managing RACI Primavera is used as SW tool for planning and scheduling of the workpackages. As a general trend, complexity is the main driver for outsourcing turnaround management. © Stichting NAP, Nijkerk 109 Annexes. Annex 1 – business case AkzoNobel: full-scale introduction of Lean-6-Sigma. AkzoNobel has its activities equally spread over 3 business areas: 1) Decorative Coatings 2) Performance Coatings 3) Specialty Chemicals AkzoNobel generates a turnover of 16 Billion Euro (2011) and employs approximately 55000 people worldwide. Industrial Chemicals is one of the business units in the business area Specialty Chemicals with a turnover of 1.2 Billion Euro, and approx. 1700 employees. Industrial Chemicals is acting in the markets of salt, chlorine, caustic soda, chloro methanes en mono-chloro-acetic acid (MCA). It has leading positions in Europa and is leading globally in MCA. MCA facility at Delfzijl, Netherlands Situation/Tasks: © Stichting NAP, Nijkerk 110 In the past various CIP programs were executed with results limited to only parts of the organisation and with restricted sustainability; most were executed on production locations Today’s strategy includes 3 pillars: operational excellence, sustainability and profitable growth Target: create added value of 1-2% of the annual cost base Activities: Kickoff 2009: Operational Excellence masterclass Starting January 2010 Lean Six Sigma was implemented in the Business Unit As part of Talent Factory and MD programs Black Belts were selected from a group of high potentials; the vacancies were filled with new talents The L6S program was to be deployed across the entire BU and was to facilitate a continuous flow of improvement projects for multiple years Results: L6S projects have been running for 4 years and continue to be executed Continuous in- and outflow of Black Belts, with a steady number of approx. 15 dedicated Black Belts, running 1,5-2 projects each The program benefits (based on EBIT) for the 3rd, 4th and 5th year were planned to be 2x, respectively 4x and 8x the costs 2013 will be the 4th year and the planned return on investment will be made easily (>> 1 M€) Examples of results: The Chlor-Alkali business had ca. 300 tank wagons contracted; a considerable amount was not utilized. With L6S the utilization grade was improved significantly. In Ibbenbüren the use of cooling water of about 3000 cubic meter per hour reduced with 20%. In Frankfurt and Rotterdam the chemical waste quantities were reduced with 40% compared to 2010. The delta between the forecasted and actual electricity consumption was reduced to below 2% in the chlorine production in Rotterdam. In the salt plants in Delfzijl, Hengelo en Mariager(Dk) a saving could be realized of more than 2 Million €/year. In several chemical plants of IC a capacity improvement was achieved of more than 10% by consistent measuring, the use of statistical analysis methods and consequently making the right modifications in process monitoring and operation. In China, Taixing, the 5S-method was applied successfully. Tidiness and © Stichting NAP, Nijkerk 111 housekeeping improved significantly. The operators have got now more time available for inspection, operation and maintenance of packing machines, resulting in a higher output. By using the L6S methodology the organization gained more understanding of the root causes of illness absence. Based on the results numerous improvements are and will be realized. Procurement: In a number of categories in Site, Operational, Consumables and Services a L6S team set up and negotiated new frame contracts with suppliers leading to a reduction of 10-15% of the purchasing price.

Interview with Francois Ramond, BU Director Operational Excellence and Nelly Nijssen, Lean 6 Sigma program office manager about working with Lean Six Sigma (L6S) at AkzoNobel Industrial Chemicals. AkzoNobel has its activities equally spread over 3 business areas: Decorative Coatings, Performance Coatings and Specialty Chemicals. (Turnover 2011: 16 Billion Euro, ca 55000 employees). Industrial Chemicals is one of the business units in the business area Specialty Chemicals with a turnover of 1.2 Billion Euro. (ca. 1700 employees). Industrial Chemicals is acting in the markets of salt, chlorine, caustic soda, chloro methanes en mono-chloro-acetic acid (MCA). It has leading positions in Europa and is leading globally in MCA. What are the critical success factors to sustain L6S successfully? FR: Ownership is the magic word. The entire organization should support it. In particular management should show real commitment by giving the right priority to improvement projects, freeing up resources and being prepared to organizational changes. L6S leads to a culture change and a new way of working, which eventually makes the organization change. Just a clean L6S implementation as methodology can be done and leads to improvement, but then there is no differentiation with other continuous improvement methods. In Industrial Chemicals it is more than just introducing a new technique. It is about making everybody aware that L6S is a different and better way of working. We do not achieve this by a top down approach only, as we applied in the first years. Not enough ownership was created. It must also come bottom up from the shop floor. That can only be accomplished when all employees are involved and there is commitment of all management levels. In this respect we have still to do more. L6S is too much seen in the organization as a program that comes on top of other programs. There is a risk that the organization perceives it as an extra pressure and feels forced by higher management to do more show projects, while it is already busy with the ongoing business and running programs like the Corporate Training Program, Eco Efficiency Program, etc. In that situation the green belt training program for lower and middle management will be insufficiently executed because there is not enough time left and the purpose to do improvement projects by L6S comes under pressure. Yet, Lean six sigma is what we want because then and only then the solutions will be accepted and carried by the entire organization and real problems will be solved in a sustainable way. Instead of spending extra time on reduction of non-conformities and rework it will become easier, time will be saved and productivity will be improved. Long term it saves time which can be used to make more improvements. So L6S becomes ‘the way of working’ in our business unit and do we use one language regardless where we are in the world. The big challenge in 2013 is embedding L6S in all layers of the organization and making L6S the only way how we improve things and solve problems. An absolute pre-condition is full management commitment of higher management. They must continuously advocate that there is only one way to improve: the Lean Six Sigma way. © Stichting NAP, Nijkerk 113 How successful is L6S after the program was launched about 4 years ago and how is success measured? FR: After completion of each L6S project the EBIT (Earnings Before Interest & Tax) is calculated and validated. It can be an extra earning or a saving either in fixed costs or variable costs. Of all L6S projects the EBIT per quarter is reported and verified by business controllers. It always concerns real earnings or savings. If a capital investment is necessary it will be fully included in the EBIT calculation. In all cases it concerns only small capital investments. In L6S we always focus on the feasibility of savings or positive financial effects. The potential outcome is compared with the ‘as is’ situation. The result is the ‘gap’ that should be closed. And that’s what we are doing: not accepting the ‘as is’ situation and continuously looking for opportunities to close the ‘gaps’. After 3 years we reached a constant level of 15 dedicated Black Belts. Yearly there is an inflow and outflow of about 5 black belts. They complete 1,5-2 projects per BB, resulting in a total of 20-30 projects annually. The offset of the returns against the investment in the L6S project (the cost of consultants, organization, program management, freeing up resources becoming black belts etc.) was negative in the first year. But in the second year we had to reach breakeven. The target for the third, respectively the fourth and fifth year was to deliver a return of twice , respectively four and eight times the costs. 2013 will be the fourth year and we are going to reach the target easily. And we are not talking about small money, but about millions of Euros. Large companies like Coca Cola, GE, Celanese, Sony, Siemens, IBM, Boeing, Dow Chemical, Merck…etc. discovered this already in the past and now also AkzoNobel, adopted L6S as the continuous improvement vehicle. More business units started working with L6S. What happened with the Black Belts flowing out? Were they satisfied with the next career step ? NN/FR: The entire first wave Black Belts accepted a new job in AkzoNobel at a higher level than the job they left before being nominated as a black belt e.g. sBU Controller, Operational Excellence Manager, Technology Manager and Key Account Manager. One of the serious goals of the L6S program is that Industrial Chemicals selects TOP talents from inside and outside the BU in order to let them grow as a Black Belt and after achieving good results let them flow to a higher position. L6S acts as a talent factory. Also during the economic recession, society is in now, we continue the program. And when the economy is back on track we have got the right people on those spots where we need skilled leaders. These leaders enhance a culture in which we do not accept an average result, but endeavor continually the best performance. And that’s what we mean with ‘closing the gap’ says Francois. In contrast with other organizations the Black Belts are fully dedicated to L6S during 2-3 years abandoning their present job. They will not return afterwards to their old jobs. New people have been recruited in those jobs in the meantime. The candidates have to go through a heavy selection procedure. The group of Black Belts acts as an extra resource and is considered as an investment in the organization. The management development part enhances the interest of potential candidates to join the © Stichting NAP, Nijkerk 114 L6S program as Black Belt. So Lean Six Sigma contributes fundamentally to the talent development program of Industrial Chemicals. The continuous improvement process that companywide has been implemented and anchored, yields in big quality improvements and savings e.g. in operational equipment efficiency, raw material and energy efficiency, quality, maximum proven hourly capacity, lifetime of equipment, project duration, logistics, the procurement process, OWC, etc. We expect a lot of our Black Belts. They are the talents, who will and must grow into higher management jobs in the near future. How show members of the BU management team commitment to L6S? FR: The Black Belts report directly to a member of the management team. The Black Belts keep weekly contacts with their bosses and meet face to face regularly. The Black Belt is frequently invited to report progress of his/her project in one of the 4 sub-Business-Units Management Teams. In the AkzoNobel Industrial Chemicals News Letter frequently successstories about L6S projects can be read. Business Unit MT-members act often as steering committee chairman of larger L6S projects. What could be improved? NN: There are still many things to improve. More can be done involving more employees in all layers of the organization in the use of L6S. The Belt trainings will be included in the yearly personal targets, agreed between employee and his manager. A better structure will be set up at the sites to promote the identification of L6S projects and to enable the sites to set up and manage the lean six sigma process. Targets will be agreed with respect to the number of employees to be trained. FR: We develop fast; On top of Green Belt and Black Belt training also Yellow Belt and Brown Belt training are performed in 2013. Yellow Belt is a one day L6S awareness training focusing on identification of improvement opportunities: ‘Gap’ identification. Brown Belt is an expert training at the sites of two weeks lead by Black Belts. The important continuous improvement techniques and the DMAIC approach is learned, and applied directly in existing improvement projects. The Brown Belts are deployed also in the training of Green Belts and Yellow Belts. It leads to a balanced approach of the improvement culture: top down and bottom up. The goal is: more than 10% of the employees trained in 2013 and more than 50% in 2015. Assuming one completed project per year per trained employee results in 170 projects in 2013, and 850 projects in 2015 spread over all parts of the business unit en over all locations (12 locations worldwide). We expect that in 2013 the point of no return will be passed and L6S will be sustainably embedded in our organization. From watching passively what happens by the majority of the people it will change in “can we join and when?” From that point the system keeps going on by its own strength and has enough momentum to sustain, supported by its facilitators and the management of the business unit. And those who still do not want to participate? They do not longer feel at home in our business unit and will make other choices in their careers. All in all, a big challenge for the management team of IC and the people of IC. Some examples of successful L6S projects in IC: The Chlor-Alkali business had ca. 300 tank wagons contracted. A considerable amount was not utilized. With L6S the utilization grade was improved significantly. In Ibbenbüren the use of cooling water of about 3000 cubic meter per hour reduced © Stichting NAP, Nijkerk 115 with 20%.
