Proc. of the 1st International Conference on Modern Trends in Industrial Engineering, November 17-19, 2011 S.V.National Institute of Technology, Surat – 395 007, Gujarat, India WORLD CLASS MA UFACTURI G MODELS: COMPARISO A D EVOLUTIO R.Gandhi1, J.Mehta2, M.Patel3, T.N.Desai4 1,2,3,4 Department of Mechanical Engineering, National Institute of Technology, Surat, India Abstract: Quality in manufacturing is no longer an option but mandatory for any company competing either on the global scale or at the domestic level. World Class Manufacturing was introduced in around 1980 and has incorporated new principles and policies for production. These principles have also undergone modifications with time and still continue to do so. This paper deals in detail with the concept of World Class Manufacturing and its journey since inception. The paper gives a comparative study of the major proposed models of WCM and describes the evolution of the World Class Manufacturing Model. It shows how any organization needs to modify over time to continuously improve and attain high levels of performance in manufacturing. Keywords: World Class Manufacturing, Evolution, Comparative Study. 1. INTRODUCTION World class manufacturing is a set of production principles which were implemented after the 1970’s to enhance productivity and profitability. The inherited pattern of mass production was trashed and an entirely new set of principles were developed. Companies had to be more competitive and this improved competitiveness in its broadest context was referred to as manufacturing excellence, and was deemed to be demonstrated by simultaneous improvements in manufacturing performance as well as business performance through indicators, such as productivity, cost reduction and market share in the world market[1]. The goals of WCM efforts include maintaining market share, improving profitability and improving the firm’s ability to compete in a global market place. 2. WORLD CLASS MANUFACTURING MODELS The term ‘world class manufacturing’ was first used by Hayes and Wheelwright in 1984. Since then, the concept has been embraced, expanded and enhanced by a number of authors, who have reinforced some of Hayes and Wheelwright’s ideas, added some new practices and ignored others [2]. The phrase was publicized by Professor Richard Schonberger (as the title of his 1986 book) wherein he suggests the term as WCM “nicely captures the breadth and essence of the fundamental changes taking place in industrial experiences.” WCM soon replaced the mass manufacturing techniques and hence the most popular, extensive and widely used WCM models are shown in the form of a flow charts indicating, the goals of the WCM, the key focus/improvement areas and the pillars on which it is based. The proposed model at the end, integrates the best of all these various models as well as others, updates the model with the latest technology available at day and presents the model in the similar pattern the goal of World-Class Manufacturing (WCM) is ‘continual and rapid improvement’. and the JIT production path. total quality control (TQC) and just-in-time (JIT) production methods. While the JIT philosophy advocates manufacturing in the smallest possible batch size. Producing more is costly and wasteful. systems. TQC and JIT is necessary to achieve business excellence [5]. equipment. which is based on the principle that ‘purge anything that does not add value to the product or service. time. Cellular manufacturing and deviation reduction are equally important to achieve world class status [4]. The integration of CIM. or human activity of any sort’. The WCM status can be achieved by any two parallel paths: the quality path. whether material.2 Schonberger’s WCM Model: According to Schonberger. These wastes as described by Shigeo fall into 7 different categories which are shown in the adjoining figure 1. which may enable a manufacturer to gain competitive advantage for reaching World Class status.1 Hall’s WCM Model: According to Hall (1987). Figure 1: Hall’s WCM Model 2. All three of these are mandatory to achieve world class manufacturing [3]. These are the three fundamental approaches in modern manufacturing.2. manufacturing excellence is attained by ‘value-added manufacturing’. TQC precepts to “do it right the first time”. He proposes two different frames of reference for achieving business excellence: one is that of the global market and second of the global competitors. Following WCM means to produce only that much which will be required for that day. This type of improvement in the key focus areas like quality. energy. space. Figure 2: Schonberger’s WCM Model 2. Figure 3: Gunn’s WCM Model . Schonberger also believed that WCM efforts must help to market the product better. Just-in-time and people involvement. cost and flexibility can enable one to compete at the global level. The framework of ‘value-added manufacturing’ is described in three overlaying categories of work: total quality.3 Gunn’s WCM Model: Gunn’s Model of WCM (1987) rests on three pillars: Computer Integrated manufacturing (CIM). quality and agility. The Malcolm Baldridge award is used by many as a benchmarking tool and it has been built upon various core values and concepts which are clearly shown in the adjacent figure 6. efficiently and effectively can become the best. World Class manufacturing includes the following: a) A new approach to product quality b) JIT production techniques c) Change in workforce management d) Flexible Approach to Customer Requirements People management is a very essential component for attaining this highest stature. Excellence at the operational level must be given more attention. Figure 5: America’s Best Plants WCM Model 2. Figure 6: Malcolm Baldridge National Quality Award .6 Malcolm Baldridge ational Quality Award: This model identifies good management as essential for achieving a World Class competitive position in the manufacturing sector. agility combines the philosophies of lean manufacturing and the techniques of JIT. educating and giving cross training for better flexibility. That is only the manufacturers which are able to change quickly. Lastly.5 America’s Best Plants Model of WCM: The characteristics of World-class manufacturing are identified by three core strategies: customer focus. The best plants are beyond merely manufacturing lines and provide value to the environment and the communities in which they operate [1].4 Maskell’s WCM Model: According to Maskell.2. He proposes few new approaches for the same like transfer of responsibility to give operators greater control of their daily work. quality circles for total employee involvement [6]. This award offers a demanding competition and puts every company to the same stringent tests. Figure 4: Gunn’s WCM Model 2. This model identifies customers as the centre of a manufacturing operation. Next to the customer is the quality which is defined as defect free and waste free. It has created a common vocabulary and philosophy bridging companies and industries and it has made learning across the boundaries of businesses possible and desirable for the managers. ii. If this step is not performed after the first three steps. the whole exercise becomes pointless and it renders the effort useless. A company can successfully imbibe the culture to become a World Class Manufacturer by four sequential steps given as follows: i. implementation is the final and the most important step in the journey towards becoming a World Class Manufacturing. Understanding: Just spreading awareness is not enough because there is no point without understanding the need for the process and hence training programs are an absolute must. Have very high levels of product and process quality: Anything less than excellent quality is not acceptable in the current scenario to be considered a World Class Manufacturer. Implementation: The organization should put the concepts into everyday use. iii. the following four building blocks begin to emerge as encompassing attributes that are a practical. Compete on the basis of time: Time is the key and a company should do whatever it does faster and with more flexibility compared to its competitors. It is a leadership initiative to suffuse the four attributes throughout the company. Acceptance: The organization and the employees should believe in the four building blocks individually and as a whole and must accept them as necessary and important in attaining the goal of becoming a World Class Manufacturer. The understanding should include how each building block impacts the business and the possible magnitude of the impact. iv. Figure 7: Proposed WCM Model . Innovate and practice continuous improvement in all aspects of business: Manufacturing companies must adopt a culture that is never complacent.After an analysis of the prevailing definition and explanations. Hence. iv. workable interpretation of World Class Manufacturing: i. never satisfied and never stops trying to improve. ii. Awareness: Each and every employee at every level must be aware of the goal to excel and become a world class manufacturer. Involve all stakeholders: Involvement of everyone associated with the company is necessary and their inputs can be of utmost value at different times for a business. iii. It was no longer a luxury but a necessity. WCM is an order or a manner of doing things. customer. “Even better quality.

Companies looked to CRM to help them manage the life cycle of a sale. The focus shifted from just Quality to “Customer Satisfaction”. at the right place. a whole range of software was created. Customer relationship management (CRM) technology must play a significant role in a customer- . Customer was always in the purview but never in focus as he was now. Customers expected high quality from their suppliers and manufacturers also in turn delivered. Quality became a pre-requisite. Stronger” was the motto and a complete revamp was underway in how manufacturing activities were carried out. Over the next decade. electronic calendars and contact information systems were introduced to the broad business world as CRM (Customer relationship management) technology in its very infancy. That is exactly what WCM was and is. The overriding goal of WCM was summarized by this motto which came from latin: Citius. Altius. Benchmarking Total employee involvement through proper managerial direction Continual improvement. Quality wasn’t something unique any longer and the World Class Manufacturing model had to evolve accordingly. “Quality” was the buzz word. the quality of products as a whole improved which was a win-win situation as producers moved towards manufacturing excellence and the customers got better quality products in return. .249–269..
