Asset Performance Management 2.0, which now incorporates emerging Industrial IoT (IIoT) approaches and technologies and new analytics solutions, uses information from production management and control sysIIoT and analytics enables the next generation of APM 2.0. This ARC Strategy Report provides insights that can help asset management professionals improve KPIs. tems in asset management applications to provide new opportunities to optimize asset availability and operational performance. Reliability studies (pg. 14) show that, on average, 82 percent of assets have a random failure pattern. Preventive maintenance assumes that the probability of equipment failure increases with use, which applies to just 18 percent of assets. IIoT and analytics, using engineered algorithms and/or machine learning techniques, provide a new means to predict failures. This can enable organizations to drive down unscheduled downtime to near zero – with a positive effect on a broad range of KPIs. Consumer electronics, including more than a billion mobile phones, drove the creation of infrastructure and provided economies of scale for the sensors, networking and cloud computing used in IIoT. APM 2.0 leverages this new capability to enable new business processes and business models in industrial organizations. APM 2.0 incorporates IIoT, analytics, and other predictive and prescriptive technologies to bring performance to a higher level. It provides a means to systematically improve key metrics like uptime, mean time to repair (MTTR), asset longevity, cost, quality/yield and safety for maintenance; and on-time shipment, quality, and inventory for operations. This optimization goes beyond functional silos and occurs between silos where significant inefficiency, waste and sometimes dysfunction often reside. Rather than accepting waste among APM functions, ARC recommends that industrial organizations develop a disciplined approach for improvements. Copyright © ARC Advisory Group • ARCweb.com • 3 ARC Strategies • September 2015 Key findings in this report for adopting APM 2.0 include: • Start proactive maintenance projects using IIoT and analytics • Target critical assets that have a random failure pattern • Use smaller pilot projects to build confidence within the organization • Consider an IIoT platform that can grow to build on success • Adopt mobile devices to eliminate paper-based work order processing • Use business process automation between systems - particularly PdM and EAM Asset Performance Management Scope Asset performance management (APM) involves improved integration of production management (making the product) with asset management (ensuring the capability to produce). The resulting alignment enables increased visibility, collaboration, and communication for higher productivity, reduced risk, and improved return on assets (ROA). Goals and objectives become more clearly communicated and shared. The ramifications extend into business processes, technology, and organizational structure.

It includes an improved understanding of risk, with fact-based risk assessment. Integrating information from production and asset management applications provides new opportunities for organizations to balance operational constraints (capacity, inventory, labor, etc.) and improve ROA. APM applies to the long, “operate and maintain” phase of an asset’s lifecycle where margins and profits are determined. With a combined view of asset availability and operational constraints, workers and managers have a richer set of data to enable information-driven decisions. APM 2.0 Collaboration With a good APM strategy, operations and maintenance groups become more collaborative, exchanging information to manage critical issues and operational constraints while improving overall operating performance. Combining the information from the traditionally separate operations and maintenance solutions improves the effectiveness of both areas, and offers new opportunities for managing risk and optimizing performance. On-time Shipments Revenue improvement P&L Drivers Equipment uptime High quality Cost reduction Cost control Less Inventory Cash conservation Balance Sheet Equipment uptime ROA; Less fixed assets Asset longevity Governance Risk Mitigation Safety Annual Report Objective KPI in APM C-Suite Drivers and Related KPIs for Asset Performance Management Copyright © ARC Advisory Group • ARCweb.com • 5 ARC Strategies • September 2015 Business Drivers for APM 2.0 C-suite metrics are included in the company’s annual report, i.e. the P&L statement, balance sheet, and risk assessments. These metrics drive the key objectives of production and maintenance. ARC has surveyed end users several times during the past decade. Each annual survey has “improve uptime” in the top position, followed by asset longevity and safety. Typically, the KPIs for operations focus on on-time delivery, quality, and lower cost of production. APM Supports Executive Metrics In the chart for “C-Suite Drivers”, executives tend to manage from left to right and “drill down” to identify issues and/or opportunities for improvement. When writing the business justification for an APM-related proposal, managers and engineers can “drill-up” by going from the KPIs on the right and connect to the P&L statement and balance sheet on the left. This approach provides the foundation for a good business case that is more likely to gain executive support by relating to their KPIs. The project justification and executive support helps assure allocation of the needed resources and management attention for successful implementation. P&L: Uptime improves equipment availability so production can meet its schedule with on-time shipments – which directly effects revenue and customer satisfaction. Improved production and maintenance effectiveness helps control and reduce the related labor, material, and equipment losses. Balance Sheet: When assets last longer, the company retains cash and avoids using it to purchase replacement assets. Higher uptime also increases capacity, which can avoid expenditures for more assets and conserves cash. Conserving cash improves the financial ratios used by Wall Street to measure the value of a company. Governance: Either intense competition or regulatory compliance drive executives to carefully manage risk. The goal of safety and risk management aligns with this concern. 6 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 APM 2.0: Impact of Industrial IoT Industrial IoT provides the enabler for next generation APM 2.0. The wealth of data provided through IIoT, combined with analytics, opens new opportunities for improving asset performance. Industrial IoT Essentials IIoT solutions have an architecture that can be simplified into three major components: • Data acquisition from various systems, equipment, devices or sensors: In the case of an owner/operator, the data usually comes from sensors attached to the control system and passes into an historian or other time-stamped database. For an OEM monitoring its installed equipment, the sensor is usually part of an intelligent device with a processor, memory, and small software applications. In both cases, the data can be process values (pressure, temperature, flow, etc.) or asset health information. Analytics • Communications, networking and security: Usually, hierarchal transfer of information occurs from sensor to control system to cloud applications. However, peer-to- Network peer communications among machines has interesting possibilities (energy management or process coordination) Historian & Controls that have yet to be applied broadly. • Cloud applications: Currently, the dominate use of the data involves analytics to predict equipment failure so Industrial IoT Architecture repairs can be made prior to a fault with unscheduled downtime. Some applications identify production or operating issues that require attention. When conditions warrant, an alert goes to operations or maintenance. Ideally, business process automation initiates appropriate workflow in the applications used by these functions. Why Now? Consumer electronics – particularly smartphones – provided economies of scale to lower the costs of sensors, networking, cloud computing and Copyright © ARC Advisory Group • ARCweb.com • 7 ARC Strategies • September 2015 application development. This cost advantage combined with high business benefit drives the current rapid IIoT adoption. New Class of PaaS Applications with Analytics and Big Data Historian and analytics software solutions have been around for at least three decades. In that time, the effect of Moore's Law has vastly improved data storage and computing capacity. Also, the number of intelligent sensors and devices feeding data has exploded. This confluence of Big Data, low-cost cloud computing, and advanced analytics enables a new class of applications. Analytics have become pervasive for finding value that was "hidden" in the data. Standardized platforms - like IBM's BlueMix, PTC’s ThingWorx, GE’s Predix, and Microsoft’s Azure (plus many other more focused IoT applications) - reduce the investments in terms of engineering and programming investments needed to implement a solution. Implementation costs and ease-of-use for these PaaS (platform as a service) solutions have significantly improved, further driving acceptance. Fail Fast, Learn, and Move On Project risk has been lowered with inexpensive IT resources via the cloud. Organizations can start with a free entry-level service to prototype and even pilot a small application. If it doesn't work, scrapping the project has low losses and organizations can “fail fast, learn, and move on.” Costs would only begin to accrue with scale up following success, and these costs would be offset by the business benefits. Industrial IoT for Avoiding Unplanned Downtime A time-stamped data repository like an historian brings pervasive access to operating data for IIoT applications. Most industrial organizations have critical equipment for which unplanned downtime would disrupt operations. A small undetected problem can cascade into a much bigger issue - much like how failure to spend $25 for engine oil could lead to your car's engine seizing, requiring a $5,000 repair. IIoT enables new techniques for condition monitoring and predictive maintenance (PdM) to enable organizations to identify issues that could otherwise lead to costly unplanned downtime, negatively impacting KPIs and executive metrics. Using process data to alarm and drive maintenance work (like the oil pressure light on a car’s dashboard) is a well-recognized concept. PdM – 8 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 which is often the “low hanging fruit” for IIoT applications - is a proven approach for improving uptime while reducing maintenance costs. Role of Analytics The software to analyze the data provided by IIoT is segmented into two general categories: engineered algorithms and machine learning. Engineered Algorithms Many types of assets (like large power transmission transformers) have well-researched and well-understood failure patterns and an extensive knowledgebase of the attributes related to failures. For specific classes of equipment, this research has been used to create algorithms to predict failures. Parameters collected from an asset go through engineered algorithms (i.e., predetermined formulas, Boolean logic, rules and/or decision trees) to determine the health of an asset. Packaged software algorithms can often provide a viable approach for developing, executing, and managing multiple types of assets and their algorithms. This software helps select process data, configure diagnostic algorithms, and create alerts that drive the appropriate actions by maintenance or operations. The process data typically comes from the plant historian and/or other systems typically incorporating OPC communications. Machine Learning An emerging technology for the analytics involves advanced patternrecognition and other types of machine learning. Open source code for various types of machine learning approaches has fueled its recent rapid speed of adoption. This technology generates an empirical model by “learning” from an asset’s unique operating history during various stable and dynamic process conditions. This model becomes the baseline profile for normal operations for a specific piece of installed equipment or a broader processing unit. The learning system automatically compares an asset’s model with real-time operating data to detect subtle changes. These changes provide early warning signs of impending equipment failure before they reach alarm levels and possibly an unplanned shutdown. Though machine learning can operate with a limited number of existing sensors, IIoT offers a richer set of process data (variety, volume, and veloci- Copyright © ARC Advisory Group • ARCweb.com • 9 ARC Strategies • September 2015 ty) for a higher fidelity model with improved condition monitoring and asset reliability. The combination of these two emerging technologies offers an opportunity to take prescriptive maintenance to a new level. Case stories indicate that the combination of machine learning with a large number of IIoT sensors provides more advanced notice of a pending failure than traditional, single-variable condition monitoring systems. Positioning Engineered Algorithm and Machine Learning With many of the same asset and well-understood operating parameters, the engineered algorithm usually provides a good fit. A machine manufacturer with standard products has the economies of scale to create software for monitoring its equipment via the internet and sell aftermarket services for predictive maintenance and reliability. In some cases, an end-user has many of the same type of asset, providing similar economies of scale. As discussed in a previous ARC report, the Sporveien case story (for doors on passenger trains) provides a good example. Machine learning provides a good fit with more unique equipment or processes. Usually this involves an end user with a critical process step that could result in expensive unplanned downtime. A common approach has the machine learning application reading data from the historian. Initially, many false-positive alerts will occur. The software must be “trained” to improve the proportion of positive alerts. This can take from as little as a few days to as much as six months, depending on the sophistication of the machine learning software and the scope of the process being monitored. Critical factors for success include: • Authorized trainers with deep expertise and can provide accurate guidance to the machine learning algorithm • Prescriptive information when an alert is generated to help humans assess priority and diagnose the issue (otherwise, they will ignore it) Industrial vs. Consumer IoT Adoption Including Industrial IoT in a project involves decision makers who usually require a clear benefit and corresponding business case. Frequently, a sponsor or “recommender” investigates, determines how the benefit will be derived, and includes IIoT in a proposal. Management reviews and either approves or denies the project. This leads to a rational, business-driven decision. Industrial IoT involves projects with clear business benefits. 10 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 Consumer IoT includes use in products like smartphones, wearable fitness trackers, smart thermostats, connected cars, and many other product categories. Consumer IoT typically has a low price-per-unit and high volume compared to industrial applications. With the low price, we sometimes see fad-like buying patterns. Getting to APM 2.0 Asset Management Strategies Asset management strategies can generally be classified into four types: reactive, preventive, predictive, and prescriptive. We’ve intentionally kept the examples included here basic and generic. Reactive – Run to Failure Reactive is the most common approach to equipment maintenance since the majority of assets have a very low probability of failure and are non-critical. This is appropriate in many cases and helps control maintenance costs. However, when a failure does occur, the broken component can cascade into other components and become a major expense. Much like not servicing the engine oil in your car, running to failure, and having a $5,000 engine replacement because the bearings seized. This approach is only appropriate for non-critical assets. Preventive Maintenance Manufacturers often employ a preventive maintenance approach. Here, maintenance is performed based either on time (replacing the batteries in your household smoke detectors once a year), or usage (changing your car's oil every 5,000 miles). Preventive maintenance fits when wear with age, run time, or number of cycles provides the driver for failure (i.e., assets with an age-related failure pattern). Periodic inspections and condition evaluation are often used for stationary plant equipment such as steam boilers, piping, and heat exchangers.

The applications involve the more critical assets for which failure would significantly impact uptime, asset longevity, safety, product quality, or involve major repairs. Typically, the monitoring involves a single asset attribute, such as vibration or temperature. One PdM approach uses process or device data to assess the current condition of the equipment. This data often comes from the plant historian and is used with an algorithm to predict failure. Another approach for PdM involves a separate plant asset management (PAM) system for condition monitoring. Commonly used sensors include vibration, infrared, ultrasonic, oil analysis, and corrosion. PAM systems are usually applied to rotating equipment (pumps, electric motors, fans, internal combustion engines, and presses) and related automation assets. Prescriptive Maintenance Prescriptive maintenance combines data (usually from a particular device or system) with algorithms that model that type of equipment (virtual equipment or “digital twin”) to monitor condition and raise an appropriate alert when appropriate. The data from a particular device, combined with algorithms engineered for that type of equipment, provide a means to assess condition and identify a problem before it cascades into a much larger problem that could impact business performance. 12 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 One benefit of the specific algorithm or model is the ability to replicate it like a template across many similar devices in a large network – like doors on a passenger train or transformers in power transmission lines. Another major benefit of using a model is the longer time horizon provided for notification of an issue. Here, integrating the alerts into other applications and business process automation (BPA) becomes important since humans tend to forget long-term issues (more on this BPA later). Also, technicians must be provided with specific information to help them understand and diagnose the problem, so they won’t just ignore the alert.

Benefits with APM 2.0 and Higher Maintenance Maturity As one moves along the maturing curve from run to failure and towards preventive, predictive, and prescriptive maintenance; improvements occur in the core KPIs for asset management and maintenance: uptime, asset longevity, cost control, yield/quality, and safety. Note that some industries, such as refining, rank safety higher. These KPIs relate directly to executive metrics for the C-suite – hence their importance. Copyright © ARC Advisory Group • ARCweb.com • 13 ARC Strategies • September 2015 Reduced Maintenance Costs Predictive maintenance allows maintenance staffs to anticipate failures, schedule work orders, and prevent failures. A study by a major petroleum company showed that, compared to calendar-based preventive maintenance, a predictive approach reduces maintenance costs by 50 percent. The specific benefits reported: • Maintenance costs reduced by 50 percent • Unexpected failures reduced by 55 percent • Mean Time Between Failures (MTBF) increased by 30 percent • Machinery availability increased by 30 percent Improved Maintenance Execution At the lower level of asset management maturity, the EAM system is used primarily for record keeping to document past reactive activities. It provides supervisors a means to explain how resources were expended, and perhaps justify the next budget. This is akin to "managing through the rear view mirror.” With higher maturity and less reactive activity, the EAM system becomes a proactive management tool for planning, scheduling, and prioritizing resources to prevent failures and unplanned downtime. Mitigating Aging Workforce The aging workforce issues include the difficulty hiring replacements willing to work in an industrial setting. Some have forecasted double-digit reductions in the available workforce for industrial companies in developed countries. With the combination of fewer people and continually aging assets, more effective maintenance practices are required. Performing maintenance when conditions warrant (prescriptive) rather than periodically (preventive) requires less labor and can help mitigate issues associated with the aging workforce. APM 2.0 Needed for 82 Percent of Assets Preventive Maintenance Fits 18 Percent of Assets Preventive maintenance assumes the probability of equipment failure increases with use, and schedules maintenance based on calendar time, run time, or cycle count. However, data on failure patterns from four different studies show that (on average) only 18 percent of assets have an age-related failure pattern (reference the next chart). Thus, preventive maintenance provides a benefit for just 18 percent of assets. 14 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 Prescriptive Maintenance for the Other 82 Percent Doing a preventive maintenance on the other 82 percent may well cause failures by placing some assets at the beginning of the Type B curve for early life failures. APM 2.0 with prescriptive strategies using IIoT and analytics to identify randomly occurring failures provides an appropriate maintenance strategy for the other 82 percent of assets.

Usually, each organizational silo has been optimized to meet its metrics – if not the manager would have a job continuity issue. However, cross-functional activities between the organizations often get less attention. Disconnects between the Silos within APM The difference in metrics among the functions within APM often leads to disconnects, delays, and sub-optimal overall performance. The key metrics for maintenance typically include equipment uptime, asset longevity, reliability, and cost control. Production has a different set of metrics that includes on-time delivery, quality/yield, quantity, and control of production costs.

This needs to change. Business Process Automation Connects the Silos It does no good to identify a pending failure, but not take appropriate preventive action. Unfortunately, most organizations operate in silos, with 16 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 only ad-hoc communications between operations, reliability, maintenance management and technicians. Too often, identified problems become lost, resulting in a failure to take action and, ultimately, unplanned downtime. Workflow improvements involving application integration for business process automation avoids lost alerts. Combining IIoT with application integration helps assure fewer “lost” issues providing higher uptime and asset longevity. Control System Process Data PdM with Historian, CBM, or Analytics Mobile EAM System Alerts or Flags Planner Work Orders Process Execute Work Order IIoT with Business Process Automation and Workflow Improvement PdM = Predictive Maintenance; CBM = Condition Based Maintenance High Data Quality with Mobile Devices Paper-based processes tend to create delay and data quality problems that negatively impact system integrity. With paper-based work orders, the busy technician writes up the work order on paper, but typically doesn’t enter the data into the system until the end of a shift when he or she can find the time. As a result, data quality suffers. In other cases, the paper goes to a data entry person who must interpret handwriting and again data quality suffers. Manual Data Entry Errors Undermine IT Systems In the ‘70s, as part of the evaluation of newly introduced barcode systems, a study found that data entry using a form with just 80 characters had a 10 percent error rate. More recently, findings show that manual data entry error rates range from 10 to 40 percent. 1 Also, paper cannot be tagged, “Quality Management for Organizations Using Lean Six Sigma Techniques” 2014 by Erick Jones, page 520 1 Copyright © ARC Advisory Group • ARCweb.com • 17 ARC Strategies • September 2015 searched, or automated. Paper, with its inherent data integrity and manual processing issues, undermines the effectiveness of IT systems. When people don’t trust the system, they create workarounds and manage activities manually; resulting in declining productivity and increasing waste. Since the data cannot be trusted, the corresponding system devolves into a historical record rather than a tool for proactive planning and management. Data Collection at the Point of Action Mobility for asset management applies to maintenance and field service workers whose daily workflow involves going to where the equipment is located to perform their assignments. These mobile workers include technicians, craftspeople, dispatchers, maintenance, and other personnel who physically move about the facility or among customers. Accuracy improves when technicians use a mobile device to process work orders and enter data as part of their workflow while doing the work. This dramatically improves the timeliness of work order processing. The mobile device also provides the opportunity to check for errors and validate data. In addiMobile Technician Source: Schneider Electric tion, with mobility solutions, technicians can be given work order information, asset history, spare parts inventory, repair instructions, location, travel directions, maps, and make queries. Managers use mobile solutions to assess KPIs, assess status, and make decisions.

Accurate data and work order status elevates the integrity of the application to provide a viable, accepted, and trusted tool for management. Master Data Management Data inconsistency, incompleteness, ambiguities, and latency will occur between silos. This drives a need for some form of data standardization, which can range from simple translation look-up tables to cross-silo naming conventions. For initial pilot projects, it’s best to keep this data management methodology simple. When the pilot projects succeed and are extended to a broader enterprise, organizations should consider including an appropriate level of master data management. Recommendations APM 2.0 incorporates the potential of IIoT and provides a strategy for systematically improving key metrics like uptime, mean time to repair (MTTR), asset longevity, cost, quality/yield, and safety. Rather than accepting waste among APM functions, ARC recommends that industrial organizations develop a disciplined approach for improvements. Based on research and analysis, ARC recommends the following actions for owneroperators: • Start predictive and prescriptive maintenance projects using IIoT and analytics. Consider targeting those critical assets that have a random failure pattern – for which preventive maintenance is ineffective and can be counterproductive. Focus on the “small data” for a specific type of equipment. • Use smaller pilot projects to build confidence within the organization and get the skeptics on board. Avoid going directly to a large, expensive, and high-risk Big Data initiative that will take too long, resulting in decaying executive support. • Start with an IIoT platform and architecture that can grow so that you can continue past the first project completion and build on success. Copyright © ARC Advisory Group • ARCweb.com • 19 ARC Strategies • September 2015 • Wherever possible, eliminate paper-based business processes – particularly those involving data collection by technicians and operators – to assure data integrity and confidence in the associated APM systems. Adopt mobile devices for the mobile technicians. • Automate the business process to connect the alerts generated by the predictive maintenance application with the EAM system so that issues get attention. Avoid dependence on ad hoc communications among functional groups. • As part of the supplier selection project, include a review of the vendor’s IIoT strategy. Those with a solid strategy will have a first-mover advantage, and a more sustainable business. 20 • Copyright © ARC Advisory Group • ARCweb.com ARC Strategies • September 2015 Analyst: Ralph Rio Editor: Paul Miller Distribution: MAS and EAS Clients Acronym Reference: For a complete list of industry acronyms, refer to our web page at www.arcweb.com/Research/Lists/IndustryTerms/ KPI APM Application Performance BPA Key Performance Indicator MOM Manufacturing Operations Management Management Business- Process Automation BPM Business Process Management MTTR Mean Time to Repair CBM Condition-based Maintenance OEM Original Equipment Manufacturer EAM Enterprise Asset Management PAM Plant Asset Management PdM Predictive Maintenance IIoT Industrial IoT PLM Product Lifecycle Management IoT Internet of Things RCM Reliability-centered Maintenance IT Information Technology ROA Return on Assets ERP Enterprise Resource Planning Founded in 1986, ARC Advisory Group is the leading research and advisory firm for industry.
