The analysis framework details the extent of automation,human and machine interactions and the application of computer based technologies in the Kenya manufacturing industry.The study population consisted of managing engineers in the leading manufacturing companies within our sample scope.We concetrated our space in Nairobi region.The study adresses the managers perception on the eventual structural and individual adjustments that come with implementation of some Advanced Manufacturing methods(AMTs).This work involved designing of a likert survey questionnaire which was presented to the respondents by physically visiting 24 manufacturing companies and utilising the web-based surveyby emailing it to 11 manufacturing companies in the Republic of Kenya.The results of this study show variable levels of automation.A large number of the manufacturing plants are applying automation and are trying to increase the automation levels their plants which comes with significant consequences on the approach to management and the actual role of the engineer in the manufacturing company. vii You created this PDF from an application that is not licensed to print to novaPDF printer

(http://www.novapdf.com) CHAPTER ONE: INTRODUCTION 1.1 Historical Developments in Industrial Automation and Manufacturing Control. Around the year 1900, factory mechanization facilitated mass production to meet the consumer's demands for improved products.By the year 1930, transfer lines and fixed automation were created to facilitate mass production.This resulted in the development of programmable automation.By the year 1950, numerical control (NC) was developed as an innovative approach to programmable automation.With the developments in commercially available computer technology, the application of computers in manufacturing started to emerge by producing a variety of new technologies By the year 1955, the introduction of computer aided design (CAD) and developments of NC resulted which led to the evolution of systems like computer NC (CNC) and direct NC (DNC) By the year 1970,developments in CAD applications and computer aided manufacturing (CAM) based systems introduced the concept of CIM, which are collectively named as AMTs (V S Nagalingam and G C I Lin (1999)), AMTs provide flexibility as well as data driven computer integration for a manufacturing organization, in which the manufacturing technology utilized is intelligent enough to process the activities with less human intervention. AMT is used as an umbrella term to describe a variety of technologies which primarily utilize computers to control, track or monitor manufacturing activities, either directly or indirectly. Technologies such as Computer Numerical Control (CNC) machine tools, Computer Aided Design (CAD), Computer Aided Process Planning (CAPP), Electronic Data Interchange (EDI) and Flexible Manufacturing System (FMS) all involve the use of computer to control tools and machines, store product information and control the manufacturing process. In addition, “technologies” or programs which do not directly involve computers are also considered to be AMTs since they are closely associated with other AMT technologies, Rahman, I., D. Reynolds, and S. Svaren (2012). 1.2 Human Factors in Production Systems As noted in the introduction of this project, automation has historically proven to be an efficient way to achieve cost-effective production in not only discrete parts manufacturing, in the process industry and in other industrial manufacturing areas (Satchell, 1998). However, automated production systems also have drawbacks. This insight into the limitations of automation during the last two decades has resulted in a better understanding of the 1 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) importance of the human operator as a controller and supervisor/manager/engineer (Chapanis, 1996; Billings, 1997). A central question in the design of physical automation and information technology has therefore not only been how to construct the best possible technical systems but also how to optimise task allocation(OTA) between the technology and its users. The initial contribution to the field of task allocation was made by Fitts in the early 1950s (Fitts, 1951), who presented a list of general tasks covering both humans and machines, illustrating where the performance of one category exceeds that of the other. 1.3 Impact Of Automation. 1.3.1 On Jobs Change in employment induced by new technology depends on how technology alters the tasks to be done in manufacturing jobs, on what changes occur in the skills required for different tasks and jobs, and on how the roles of different occupations change. Total employment change also depends on changes in how labor is used within and between industries and changes in labor supply. The effects of automation on work opportunities are so varied and (at times) so profound that they call into question the basic definition of “skill,” the identification of where skill fits into the production process, and the relationships between tasks, skills, occupations and jobs. Changes in task assignments and skill requirements vitiate traditional occupational descriptions, which form the basis of occupational employment forecasting. Managers create jobs by combining sets of tasks and allocating them to individuals (Fayols implemented principal of division of labour). Jobs with similar descriptions and avenues of preparation are classified as occupations. Indeed, the design of training programs depends on the expectation that people in designated occupations or jobs will perform specific tasks . Unfortunately for the analyst, what is actually done on the job frequently differs from the formal job description. Computer-based technologies, including numerical control (NC) technology, have already led to different staffing patterns within and among countries, varying on the basis of industrial traditions, labor market conditions,prevailing types of company structure, and national educational systems. A German analysis of flexible manufacturing systems (FMS), for 2 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) example, concluded that work within an FMS was comprised of a set of tasks that could be allocated in numerous ways generally not bound by the technology. 1.3.2On Skills Automation, through its effects on the tasks performed in manufacturing firms, also affects the types of job skills required for those tasks. In some cases, the creation of new tasks and the elimination of old ones clearly raises or lowers skill requirements.Often, however, the effect on skill demand is ambiguous, because the skills associated with individual jobs and the average skill level of a company’s jobs depend on how work is allocated among/to individuals. Skill demand also depends on how well employers understand what skills they really need. By altering the balance of work between people and machines, automation makes it possible for managers/engineers to reallocate work in ways that either raise or lower the skill requirements of jobs. OTA’s appraisal of the effects of automation on the manufacturing workplace suggests that these technologies will alter both the “depth” and “breadth” of skill requirements.Intuitively,this could lead to the need for retraining. By defination,skill depth refers to the input needed to perform an individual task or group of interconnected tasks, while skill breadth refers to the input needed to perform a set of (nonsimilar) tasks. 1.3.3 Occupational Employment of Engineers. In the manufacturing industry, engineers are a central factor in the employment changes expected to occur with automation. Engineers develop automation technologies; they work with them; yet they are not immune to being displaced by them. Engineers contribute to both the production and use of automation. The mix of engineers by discipline:- electrical/ electronic and mechanical engineers design equipment and systems, and industrial/ manufacturing engineers as well as electrical and mechanical engineers design applications. Different industries have different needs for special engineering disciplines, such as aeronautical/ astronautical, chemical, and metallurgical engineers. Typically, employers prefer that engineers have at least a bachelor’s degree, although individuals without such training can be certified by the Assosciation of Manufacturing engineers & Engineers regestration board to perform certain types of production engineering, and sometimes individuals attain the title of engineer through promotion from other positions. 3 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) Engineers who perform research usually hold advanced degrees. The employment share of manufacturing engineers with degrees reflects the fact that employers and schools alike have historically held this engineering discipline in lower regard than others. 1.3.4 Engineers as Managers. An engineer is also a manager. Good managers discover how to master five basic functions: planning, organizing, staffing, leading, and controlling. In his classic book, The Nature of Managerial Work, Henry Mintzberg describes a set of ten roles that a manager fills. These roles fall into three categories: Interpersonal, Informational and Decisional As managers, engineers will plan, organize, direct, and control various functions within firms. They may also do work similar to that of their subordinates. Programmable automation will alter the mix and number of managerial personnel. It will probably support growth in upper management ranks, for three reasons. First, the integration of databases and anticipated shifts in decision making toward higher staff levels will increase the role of upper management in the production process. The push for so-called “top down control” facilitated by computerization and automation, inherently increases the role of upper production, product variation and competition grows. More managerial input will be required for product planning and market analysis. Growth in automation products and markets is itself a source of growth in managerial employment. Third, change in production technologies may create new operational units within firms, and associated needs for planning and management. Automation generally entails new work in database management, software quality assurance and training-activities which may be undertaken by special staffs and managers. Nevertheless, it is not clear how much newmanagerial employment the support needs ofmanufacturing automation will generate, especiallywhere companies already have data processing staffs. Also, more advanced systems that do not require mastery of special languages or formats, that include applications generators, or that entail distributed data processing lower the requirement for special,in-house personnel. A study evaluating prospects for computer operations managers generally suggested growing needs for capacity planning, performance monitoring, technical support, security management, and facilities management . Also, a study of manufacturing firms concluded 4 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) that:The new technology substantially changed the jobs of supervisors and middlemanagement, shifting the focus from watchdog and disciplinarian to planning, training, and communicating. This is emphasised by manufacturing industry representatives who frequently point toresistance among lower and middle managers. 1.4Objectives of Study. The broad objective of this research is to explore how the increase in automation in manufacturing is affecting the engineer as a production manager. The specific objectivesare to study 1. How the engineer interacts with human and the ever changing technology with respect to his/her job as a manager. 2. The extent of automation in manufacturing industry in Kenya. 3. The effect of automation to the engineer as a manager. 4. The change in responsibilities of the engineer as a consequence of automation. 5. The expected consequences due to changes in the automation of production. 5 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) CHAPTER TWO: LITERATURE REVIEW 2.1 Introduction Competitiveness has made organizations to make a continuing attempt to improve manufacturing. These improvements include meeting the needs of customer, increasing volumes of output, improving product quality and reducing product costs. For a manufacturing company, Advanced Manufacturing Technology (AMT) is the answer. AMT, according to Myung, E., A. McClaren, and L. Li (2012), as any new technique which, when adopted is likely to require a change not only in manufacturing practice, but also in management systems and manufacturer’s approach to the design and production engineering of the product. These technologies can improve quality through emphasis on quality of design and can affect cost through emphasis on value engineering. Displacement of jobs is merely one of the impacts of automation. Substitution of human labour and skill with computing machinery sways economic stability, increases productivity, focus shift of highest paying jobs, unemployment. But there are many more effects of automation on engineers which will be discussed in the following review. An engineer is a manager in a production process. So we review how much the professional, social, economic and academic life of an engineer has been transformed (or is expected to change) as a result of new technologies (automation). 2.2 Automation Effects 2.2.1 On Global Scale John Diebold candidly points out the dilemma of automation (Diebold J,1959 pg2). He says that automation is “just more of the kind of stuff which creates more and better jobs all the time” and is “not essentially different from the process of improving methods of production” which has been going on throughout human history. A measure of the global adoption of AMT is reflected in a research project called the International Manufacturing Strategy Survey, which received responses from 556 manufacturers in 18 countries and found that computer-aided design (CAD), material requirement planning (MRP), local area networks (LAN), and computer numerical control (CNC) machines are now the most popular AMTs used in manufacturing (Sun, 2000). The benefits of AMT have been widely reported and can be classified as tangible and intangible. The tangible benefits, which are easily quantifiable, include inventory savings, 6 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) less floor space, improved return on investment (ROI), and reduced unit costs. The intangible benefits, which are difficult to quantify, include an enhanced competitive advantage, increased flexibility, improved product quality, and quick response to customer demand (Ariss, Raghunathan, & Kunnathar, 2000). These benefits may still offer many other improvements with respect to organizational improvements and management/worker satisfaction. For example, the process of implementing AMT might lead to better communication, redesigned workflows, or better integration of work across functional boundaries. Changes in the manufacturing environment and in technology induce organizations to change the manner in which they operate. 2.2.2 On Employees In today’s world of manufacturing, unlike other sectors in the economy, the work of wage employees is becoming increasingly complex as they find themselves having to continuously upgrade their skills to fit the latest manufacturing technologies (Carnevale, 1991; Dean, Dean, & Rebalsky, 1996). For example, compared to their day-to-day operations of the past, employees are now using less manual skills and more intellectual skills as required for operating automated machinery and processes. Their skills have also become more versatile in the variety of manufacturing technologies they apply (Markland et al.,1998; Stevenson, 1999). According to Carnevale(1991), Douglas (1997), and Gupta and Ash(1994), employees are being told less by their supervisors of what to do, as well as when, where, and how to do it, and are expected to autonomously make more decisions as members of self-directed work teams. Researchers agree with two of Deming’s (1994) long-standing opinions regarding trends in employee performance:Performance outcomes are being greatly influenced in breadth and depth by increased sophistication of manufacturing and organizational systems, and employees are being empowered to make less reactive and more proactive job-related decisions.Thisissue affects engineers and the engineering community as citizens rather than specifically as engineers. There are issues of competitiveness, international trade, the state of the economy, the health of given industries, and demographics, among others. Against a background of modest economic growth, rapid automation mises key issues for employment. Within states, manufacturing communities particularly those of automotive, agricultural equipment, and construction equipment have significantly reduced workforces when there has been large-scale restructuring. There is also a trend of up skilling, meaning that higher 7 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) educated workers replace job functions that were occupied by lower educated workers. Also the share of IT professionals and service workers has increased, while these functions have decreased for low educated workers. The number of engineers (engineers is a broad category of all higher educated technical staff, including chemists, chemical and mechanical Engineers) has increased overall, due to increases in medium educated engineers, while the share of low and high educated engineers have decreased (Van der Zee et al, 2009). The foresight study on skills (Van der Zee et al, 2009) shows that engineering functions in R&D and production, but also sales and supply change management are functions that are expected to increase. Overall employment is expected to decrease. Automation will drive competition for skilled engineers globally, as shown in a 2008 study by PWC: 2.2.3 On Management ProcessesAnd Supervisors There are a number of ways that automation technology can affect superior-subordinate relation-ships. Some are direct effects of the technology itself, others are indirect effects mediated by changes in the physical and temporal nature of work.Automated systems can affect managers’ perceptions of the degree of rationality, flexibility, and free space of their work. (Argyris, Feb. 1971) Automated systems have the capability to contribute to increased rationality. Automated systems, through their effect on the physical and temporal nature of work, can affect methods for monitoring and controlling work. This systems can make possible remote monitoring although many managers do not feel comfortable supervising employees they cannot see; regardless of the employee's personal preference or the nature of the task. Automated systems can be utilized to help increase the span of control of managers. Increasing efficiency of production process and other functions should result in greater free time for a manager (Canning, Richard G. 1974). Supervisors must be able to bring out the best from both employee and technology, and learn to make optimum use of the employee/technology relationship. To do so, supervisors must understand technology as a concept, be familiar with the latest developments in manufacturing technology, appreciate the impact of technology on the employee’s work, be familiar with employee-technology relationship problems and know how to deal with them, and be prepared to deal with the rapid and continual changes associated with modern manufacturing technology (Goetsch, 1992; Petersen, 1989). In short, the modern supervisor 8 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) should be a technically oriented team coach (Deeprose, 1995). This specifically refers to engineer’s role of controlling. 2.2.4 On Interpersonal Relations Automated systems, especially communications functions and personal applications, can reduce the quantity and quality of social interaction and social reinforcement in the office. Social needs play an important part in the motivation of individual workers (Maslow, Abraham H. 1954: McGregor, D. 1960) however, it is not clearly understood whether that motivation derives from peer group support, especially for professionals, or is purely social. Automated office systems, especially communications functions, can affect the number of "sociometric " links within an organization. The availability of a fast and simple communications link should increase the amount of communications flowing along existing paths. This impact can be positive if the communications are satisfactory or negative if conflict exists or if inappropriate messages are sent. Another danger is that the increase in upward communication can cause information overload at higher management levels and lack of ability to differentiate significant information. (Canning, Richard G. 1974). 2.2.5Academic Requirements Of Engineers There are two broad categories of employees that are of primary relevance when it comes to materials and production: engineers and assembly line workers. Some companies argue that there are plainly too few good candidates to hire and engineers tend to have insufficient understanding for the requirements imposed by new technology and the opportunities they offer, since their education and training generally have focused on metals. Engineers oversee activities of assembly-line workers. Engineering education (BSc, MSc, PhD) is more or less adequate. For all levels, additional on-the job training is necessary as new BSc and MSc graduates but also PhD’s have insufficient experience of practicalities and industrial realities and need at least a year on the job training for industry-production specific knowledge and skills. So there is a need for engineers that leave university with a more profound understanding of industrial production, including simulation, automation, logistics etc. as well as of knowledge of design and manufacturing with anisotropic materials (SRA SusChem, 2005). Cefic undertook a survey concerning skill needs of the chemical sector. For engineers, project and innovation management, next to understanding of suppliers and consumers are important. 9 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) Communication skills and team-work skills are seen as important personal skills. Also for engineers process modelling and simulation, reaction engineering and modern process design and process intensification are important. According to Van der Zee et al (2009), IT skills will become increasingly important for supply chain management and modelling and simulation in R&D and production processes. Interdisciplinary skills are important for all engineering types (R&D and production). Large multinational companies expect from the people whom they hire that they keep up to date with new technological developments 2.3Science Technology and Innovationin Kenya Kenya Vision 2030 recognizes the role of science, technology and innovation (STI) in a modern economy, in which new knowledge plays a central role in boosting wealth creation, social welfare and international competitiveness. Kenya’s prosperity will hinge on integrating its socio-economic development with sustainable S T & I policy. Technologically and scientifically, skilled workforce trained to work with modern equipment and production processes will be the pillar on which Kenya’s aspiration will be anchored. A study conducted by National Defence College (Volume 1, 2012) entitled “Application of science and technology in Kenya’s socio-economic development” predicts the following ramifications of new technology on industries, more specifically, on employment and industrialization. These are issues of primary importance to a Kenyan engineer as well.Automation in Kenya will demand the engineer to be well versed with utilization of modern equipment to produce value added globally competitive goods and services. Employment in Kenya’s manufacturing sector : Kenya’s manufacturing sector is among the key productive sectors identified for economic growth and development because of its immense potential for wealth, employment creation and poverty alleviation.Manufacturing sector makes an important contribution to the Kenyan economy and Central Bureau of Statistics (2005) reports that formal employment by the manufacturing sector is 254,000 people, which represents 13 per cent of total employment withan additional 1.4 million people employed in the informal side of the industry. Emerging Issues and Challenges facing engineers in manufacturing sector: Low technology, innovation, research and development uptake: The lack of knowledge, high cost and fear of change 10 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) has led to low technologyuptake. Similarly, there are weak linkages between the technology and researchproviders and the market. Limited technical and managerial skills:Strategic management and technical skills are not developed in a well-structuredand coordinated manner and are virtually absent in MSMIs. There is also amismatch between available technical skills and market demands due to poorlinkages between engineering training institutions and the industry(manufacturing and industry sector report, 2010) 2.4Future trends in demand and skills for engineering job functions Erick Brynjolfsson (professor at MIT) sloan school of management and his collaborator and coarthur Andrew Mcfee asserted on how rapid technological change has ben destroying jobs faster than it is creating them contributing to the stagnation of the median income and growth of inequality. In the in his demonstration by a chart Brayn show separate lines that represent productivity and total employment.For instances,4 years after world war 2,the two lines closely tracked each other,with increases in jobs corresponding to increase in productivity. The pattern is clear i.e,as businesses generated more values from from their workers the country as a whole became richer which fueled economic activity and fuelled even more jobs. In the begining of the year 2000, the lines diverged,productivity continues to rise robustly,but employmnet suddenly wilts.By 2011,a significant gap appears between the two lines showing economic with no parrallel increase in job creation.The two called it “the great decoupling”.Prof says he is confident that technology is behind boththe healty growth in productivity and the weak growth in jobs.Its a startling assetion beacause it threatens the faith that many economics place in technological progress in the nearing future. Computer technologies are changing the types of jobs available and are not always for the good.High paying jobs requiring creativity and problem solving skills often aided by computers have proliferated.The improvements in technology have changed the nature of work and destroyed some types of jobs in the process.In 1900,41% of americans worked in agriculture,by 2000 it was only 2%.Likewise the proportion of americans employed in manufacturing has dropped from 30% in the post world world war2 years to around 10 percent.Todaypartly because of increasing automation,especially during the 1980s.Certainly,the worst consequence would be to have skills which are nolonger needed by the employer 11 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) CHAPTER 3: METHODOLOGY 3.1 Objectives of Survey This study attempts to investigate the topic, “ Automation in the manufacturing industry and how it affects the role of the engineer as a manager” having wider practical perspectives while specifically concentrating on the impact of the automation implementation on the engineers performance.A list of the survey objectives were listed under the aim of the study subtopic 3.2 POPULATION AND SAMPLE SIZE The target population of this survey is the manufacturing companies in Kenya , narrowing our scope to the Nairobi area due to proximity reasons. We obtained the list of companies(attched apendixe D) in from;(KAM) Kenya Association of Manufacturers, (KEPSA) Kenya private sector alliance and (KRA) Kenya Revenue Authority.For this study the companies,which have been selected were precisely manufacturing companies. KAM groups industrial sectors into twelve categories but for our research situation,we grouped similar companies together and formulated six categories.Sampling of companies to be visited was done putting into consideration their location ( the study is biased to companies based in Nairobi area).An estimated 35% of the manufacturing companies in Nairobi.The bear minimum percentage threshold used.In this survey two methods have been employed ;physical presentation of the questionairre and the internet(e-mail based) methods. A total of 33 companies were identified and contacted.This number was largely influenced by the constraints in financial recourses other than the former reason.for the first method, the questionnaires were physically presented to 23 manufacturing companies andfor the second method an e-mail message sent to the remaining 10 manufacturing companies.Definatively,the traditional physical survey involves presenting the questionnaires in person to the selected companies while the online survey involves sending an email with soft copy version of the same questionarre. 3.4 Scaling of Responses and Response Rate Scales are ways of ordering possible responses to a question .The primary objective of the questionnaire is to ensure standardization and comparability of the data across interviews where everyone is asked the same questions.There are various types of questionnaires namely:- open-ended and close ended types.we utilised the close ended types.The close ended types are;-Likert-Scale,multiple-Choice,Ordinal,categorical numerical and the cumulative 12 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) scale types..The type of scale used was a likert intervalscale kind of a questionairre. This is one of the most common scaled-response format questions in survey design today is the Likert scale.Our reasons for choosing it were;ability to provide the necessary information,consideration to the respondent,ability to meet editing, coding and data processing requirements.Specifically,the one used toaddress the research objective in this research paper is of the 5-point Likert scale format.The selection options used were very;satisfied ,satisfied ,neither satisfied nor dissatisfied ,dissatisfied and very dissatisfied Apart from the problem of response errors that have a bearing on the reliability and validity of the survey and consequently the research study, the problem of low response rate has always been a major cause of concern to any researcher.During our visits to most privately-family owed companies there was an obvious reluctancy demonstated. We managed to get data from physically visiting 21 companies and through email, we got replies from only 3 companies. This resulted in a total of 24 companies to analyse. Several companies were either uncooperative or the production managers were not available at that moment.The various types of non-response are grouped and mentioned below; Companies outside the Nairobi eg;Bata ,located in Limuru; and Companies refusing to co-operate eg; New KCC, Pipemakers and Change of addresses or wrong addresses eg; Furaha gin manufacturers. 3.5 Questionnaire Design The physical survey materials werea 4 page printed questionnaire, A cover letter (refer to Appendixes B & C )printed on the official letter head of the department of Mechanical and Manufacturing engineering, University of nairobi, stamped and signed by the chairman. A physical survey had a coverage of 33 of the manufacturing companies in Kenyan.This were Nairobi-based manufacturing companies.Similarly a procedure was used for the emailbased survey, difference being that no printing was conducted. The draft questionnaire, which relates to the survey’s objectives had been divided into three sections to look at several aspects of an engineers job.The details are as per appendix C. 13 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) CHAPTER FOUR: DATA ANALYSIS 4.1 Introduction This chapter covers the analyses of the results obtained from the survey, together with the comparison between traditional physical presentation mode of survey and web based survey specifically delving into the email based mode. The main software used in this task is SPSS (Statistical Package for the Social Sciences),which is a data management and analysis product produced by SPSS, Inc in Chicago,Illinois. In SPSS, some descriptive statistics such as,frequencies, and charts have been used in the analysis of these results, also correlation and t-test techniques have been used to find out the relationship between some variables. 4.2Response 4.2.1 Response Rate The apparent disadvantage of on-line survey is the comparatively low response rate. In this survey the questionnaire was physically presented to the sample population. The response rate of the physically presented questionnaire and the emailed questionnaire were 91.03% and 33.33% respectivelyof the initial questionnares presented. Conclusively, this resulted into a total of 72.727% response rate. This could have been better though in this light of massive constraints, its satisfactory. From Figures 4.1, it is clear that the response rate in physically presented survey is much higher than the response rate in the web based survey (email-based survey). This finding is in line with Dommeyer and Moriarty’s argument that online data collection methods do not result in higher response level. This also supports the work of McDonald and Adam who found that the response level of online data collection method is far less than half that of the physical data collection method. 4.2.2 Response Time Short response time certainly is one of the anticipated advantages in ideal conditions of online surveys. Online surveys allow messages to be instantly delivered to their recipients, irrespective of their geographic location Ray,et al in their survey of on-line surveys, found that 34% of the on-line surveys took less than two weeks, 33% between two weeks and one month and 33% longer than one month. 14 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) In this on-line survey, the first message through the email- based mode of online survey was sent on the 2nd February 2014. About 6 5% of responses had been received within a day of the message being sent.The reminder emails were sent on 10th february 2014. About 22% of the responses within a day of the message being sent.The process of checking the email account for the remaining responses continued till the 17th of the month Therefore the period of time for on-line survey was about 17days. As for the physical survey, the first responses varied.There was not a definitive approach of estimating the patterns of response. This highly depended on the individual attitudes of the managers,the bureaucracy in the companies and the availability of the respondents which highly depended on their schedule.They took longer times and proved cumbersome due to transport logistics. 4.3Data Quality and Cost Schonlau et al have demonstrated that data quality is usually measured by the number of respondents who have,intentionally or unintentionally,missed at least one survey item or by the percentage of missed items on the respondents’ questionnaires . In the online survey no variables was found that have no information in the survey’s database (respondents did give all required answers). Same to the physical presented survey questionarres.Based on these findings it appears that the respondents had a good understanding of the variables in the questionarres. Most of the facilities involved for online survey like the internet for sending and receiving the emails were available in the university.Even though the school provided desktop computers,PCs were preffered for reasons of data security and easy access,so it is possible to say that there was only marginal cost involved for online survey due to the of internet access etc. For the physical survey the costs involved were largely the transport and printing costs,food and drinks in the field. 4.4 Research Questions 4.4.1 Research Question One This question read: The following consequences can be expected to the role of an engineer due to changes in levels of automation in manufacturing. 15 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) This question sought to find out how much some managerial roles of engineers have been affected by automation. The engineer, as a manager, is responsible for functions such as communication, staffing, decision making, controlling and leading. It seeks to find out the effect of automation on the engineer as regards to motivation, retraining, hierarchal structure, performance, work relations, production control and modes of communication. All of this factors influence managerial capacity of the engineer. In tables 4.1 and 4.2 below, numbers have been used to represent the following responses; strongly disagree – [1], disagree – [2], neutral – [3], agree – [4], strongly agree – [5] Tables 4.1 and 4.2 show statistics of the responses given for every question.

With optimum work relations,the production levels are bound to go high.This will have positive implications to the management practices of the engineer incharge of manufacturing. Need for retraining:Most,if not all respondents from the 24 companies had an absolute conviction that changes in automation levels had a retraining implications.The systems have to be mastered as the need a different approach in there operation is imminent.This is reflective on the broader scale as the current engineering training trends are shifting to specifics eg;- design engineering is becoming a key requirements as the manufacturing industry starts to evolve into nano-science/precision engineering where efficiency in the most prioritized element of mufacturing. Change in hierachial structure of command: The flow of information from policy to implementaion varies due to restructuring that comes with automation. From basics eg;-the need for messengers become obsolete with intallation of intercoms. The methods of operation from books keeeping to innitiation, monitoring of operation and quality control means systems are more self checking nd balancing. This means a more vertical and direct structure of management. figure above illustrates the distributions of the respondents opinions. Reduction of motivation levels: Automation largely does not reduce motivation. Reading through some of the closing remarks of the respondents, the manager is motivated. Nonetheless, there were a big number of respondents who were indifferent to the motivation aspect that comes with automation.That represented 41.7%, considerably big percentage. Improved production control by the manager: The survey conducted indicated that most respondents had an increase in product outputs from the inception of automated manufacturing proceses. This included the high level monitoring to efficient systems that 50 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) handle higher volumes of raw material and reduced processing time this had a close relation to the the levels of production control. By relative sense improved production control would be replicated through better perfomance output.The respective percentages of both responses were above 66% for agree and strongly agree combined. The research revealed that this was not a shear coincidence but a statistically consistent trend. The confidence in the positive automation impacts coincided with the percentage distribution of the adapted systems of automated manufacturing technologies.For instance,the distributions had the same respondents having a management role on companies with a technological dstribution that was relative to the effect to the role of engineers. Reduction of the order processing time: Companies who invested substantially in automation technologies reported more than 60 percent improvements in reduction of the order processing time,especially those companies in the food and bevareges sector. 5.1.1 Automated Manufactured Technologies The analysis of the survey in general,indicates that the use of automated technologies in the manufacturing industry in Kenya is relatively low and at the same time indicates that the implementation of automation technologies will increase in the near future.It was only one type of technology (Computer numerically controlled machines) that indicated no plans of adaption in a sizeable fraction of companies in the sector at 16.7%.The majority slots varried around 4.2%.A significantly low percentage. Most manufacturing companies have a great enthusiasim and desire to implement CIM,CAM,FMS, FMC and SPC in future.Reasons may be that the automated manufacturing (CIM) covers all aspects of design,planning,manufacturing,distribution and management of products and plants.For the production phase, manufacturing managers are interested in continued production,minimum stock piling and bottlenecking . Of all the types of manufacturing CIM was identified to be the type that is intensively used.This stood at 50%and a cummulative percentage of 91.7%. This pointed to the changing trends in the utility element a modern manufacturing process demands from the engineer.The mode of automation rankingthe least consideration is the JIT method hitting a 4.2% low. 51 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) intensively used Valid JIT MRP CIM CAM FMS Total Frequency 1 6 12 3 2 24 Percent 4.2 25.0 50.0 12.5 8.3 100.0 Valid Percent 4.2 25.0 50.0 12.5 8.3 100.0 Cumulative Percent 4.2 29.2 79.2 91.7 100.0 Table 4.59: Frequency table for automation technologies applied 5.1.2Improvements In Management Practices Due To High Automation Levels This section presents the improvement achieved in managers roles through applying high automation in all categories per sector of plants as per KAMs grouping.Six parameters were measured,i.e Rationality,Mangers layout,Flexibility,Design decision,Free space and Reduced quantity /quality of social reinforcement. This is presented with respondents agreement range of 12.5% to 62.5% whilst those who strongly agreed ranged from 4% to 29% with a cummulative percentage of both agreed and strongly agreeing ranging from 16.5% to 91.5%. This were key determinants in reduction of order processing time, increased delivery scheduling effectiveness,shorter delivery time,increased procedure and transparency,increased product quality,reduced inventorylevel,Increased information production flexibility, planning accuracy and reduced administrative expenses. Reduced inventory level: It is evident that most of companies which invested substantially in automation technologies incurred improvements in reduced inventory level, especially those companies which have production volume highly dependant on perishables. The systems reduced production costs as electricity bills emmanating from refrigeration. This aspect reduces the risks of possible losses to be incurred as they are passed over to the producer. Increased production flexibility: The results show that most of companies who invested substantially in CIM and CAD technologies achieved increased production flexibility , especially those companies from the metal sector.The level of management is is more sophisticated as the tasks and objectives are completely unique from the traditional ones of abstract verbal order issueing. The question possed being, “What is the workload to the manager/engineer in the following levels of companies?”This was an evaluation to determine the intensity of the need of human rescource requirement in automated manufacturing technology. Most semi automated 52 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) companies highlighted no change in the task levels, this stood at 75%.Respondents indicated there is very much a work load to the engineer.This stood at at 33.33% of the 24 respondents interviewed.This was analysis that was carried out in a general sense of the manageral roles in the three distinct automation environments. Analysis of the results shows that companies which have a high automation levels had a less conjested,elaborate and organized pattern of the role of the engineer.For companies with a level of automation in medium or less, have achieved improvement in reduction of the order processing time. This information is collected from remarks of the respondents. 5.2CONCLUSIONS The following conclusions can be drawn;-The response from the industry was more positive in postal survey than web-based Survey.However,the web-based survey is uses less time and less costly.This project has elaborated the possible implications of automating key areas in production systems.The survey results from manufacturing companies in the country suggest that automating operative decision-making may be questionable, while tactic and strategic decisions could be supported by automated decision support systems. The level of automation within the manufacturing industry is extremely variable.Manufacturing plants within the food and bevarages sector are dominant in terms of mode.In a sample space of 24 companies they formed the biggest fraction compared to other individual sectors. Chemicals and phamaceuticals industries are generally highly automated and are motivated for future development.While, manufacturing plants in the motor vehicle assembly demonstrated less enthusiasm towards automation. The current automation application in kenyan manufacturing industry does not depend on the computer technologies only but rather also on the intergration with the human role which is a powerful tool in fostering optimized utilization of the automation facilities.The survey results showed that, Quantity to meet user need,Subject relevance,Cost effectiveness,After sale maintenance,Currency of information,Reduction in man-labour(blue collar), Distributed access,Period of Access,Added Value in manufactured product,Ease of accessibility,Durability and Utility reliability were key in determining the type of technology to be adapted. The advanced role of the engineer means that additional resourse value should be attached in terms of knowledge to deal withthe new machines.This is achieved through retraining.A variable that demonstrated a 70.1% fraction of respondents who both agreed and strongly 53 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) agreed.This proved the convinience of autonomy,which in contrast to traditional task allocations, also considers more open and flexible work settings that involve interpersonal interaction as well as advanced human-machine interaction and system automation.This was the established equilibrium in the engineer management functionalities emanating from the shifting role due to automation. 5.3 RECOMMENDATIONS Based on the research results , recommendations for further work is appropriate .These would entail;1. Extensive research should be carried out country wide, 2. Real case studies should be conducted to assess how automated manufacturing has been used in selected manufacturing sector. 3. Develop a guideline that allows companies to choose the most appropriate automation level to be implemented to justify the implementation cost and provide optimum relation with the human resource. 4. Study and develop a guideline for the human-machine transition in quest of adapting proper automation levels with minimal negative consequenses. 54 You created this PDF from an application that is not licensed to print to novaPDF printer (http://www.novapdf.com) REFERENCES 1.
