A study of differentiation in Engineering Change ¡VAn Example of Implementation of Engineering Change in TFT-LCD Industry of Taiwan

Chen, Chiu-Yueh 08 August 2006 (has links)
On account of the rapid change of the consuming market and the industry market and the widely shortening of product¡¦s life cycle, confronting the stress from the market end, the competition strategy of the enterprises has conversed from pursuing high quality and low cost in the past into the strategy of satisfying customers¡¦ requirements. With the influence of satisfying the customers¡¦ diversified requirement of products, in addition that the trades shall continue taking consideration of the original factors of low cost and high quality, factors like the launch time of products, the speed of delivery date and the satisfaction degree of the customers¡¦ requirements have even become the key ones if the enterprises can maintain their competitiveness. Being facing with the threat from low labor cost of China, India and countries in South-east Asia, the superiority that OEM industries used to have has no longer existed and the only competitiveness they have lies in the R&D design capability. In consideration of this, the enterprises have developed toward globalization commerce and the mode of collaborative product commerce and implement the collaborative product commerce to create an superior R&D environment of products in accommodation with the rapid changed competition markets and integrate and cooperation with the supply chain in the upper and lower reach manufacturers and expect to set up systemized procedure from the process of product R&D to the production so as to promote the service quality to the customers as well as to decrease the failure cost of direct material and supplies and shorten the affect Time to Volume to the turnover and profits and further achieve the earlier winning chance of Time To Market and elaborate multiple strength. Under the circumstance that the speed of customers¡¦ favor to the products and its change have become faster and faster, the life cycle of products has then become shorter and shorter and the characteristics and appearances have also become more and more complicated, which have generated situations such as the structure value of products continually changed and increased, giant increasing information quantity and activities of frequent engineering change. Engineering Change (EC) has thus become an essential and important process in the whole products life cycle. How to fast and effectively deal with the engineering change with collaborative cooperation mode and shorten the products¡¦ launch cycle and ensure the quality and the satisfaction degree of the customers shall be considered as one of the important factors that the enterprises maintain their competitiveness. In view that the operation procedure of product R&D is very complicated, during the process the customers¡¦ requirement, technical demands and the capability of the suppliers may be changed due to the time and condition. Therefore, whether to shorten the time of product development and design shall become the key to determine if the enterprise can accomplish in taking the lead in the business field. According to the investigation, to the senior supervisors of an enterprise, most answers to if the time of new products development and change time of products¡¦ design are important are positive. Such answers also mean that the related issues like the procedure of R&D design and the shortening of engineering change procedure are one of the most popular topics in this trade. PTC and Reed Research Group have proceeded a research in object to more than 200 senior supervisors in charge of new products development and management in the global electronic and high technology companies. The result of the research has shown that the leading trades have gained more than 20% growth of revenue through promoting capability of products development and also gained multiple profits. The extraordinary performance of these companies with high growth is attributed to (a) products planning tools and the use of practical methods (b) mutually establish standardized internal and external coordination with cooperated partners (c) the design staffs have gained at an early date three products development capability like the enterprises and the information of supply chains and are enforced to carry them out so that that are able to implement high efficiency and conform to progress and budge and to keep tracking and solving the potential problems soonest within the design cycle. [1] On the basis of the above-mentioned results of investigation, we find that how the enterprises apply tool like Collaborative Product Commerce (CPC) to carry out the engineering change operation under the collaborative environment and further shorten the development and design time of new products and achieve the requests of diversified customers, low cost, high quality and short delivery date and finally become one of the topics that nowadays the enterprises are eager to learn. Engineering change management (ECM) is a sort of changed management in object to the released parts, blueprints, and software during the process of R&D or production and is one part of product R&D procedure. Because it is essential for each stage within the development life cycle of the whole products to carry out engineering change, therefore, the study has proceeded conferring the adjustment condition among the engineering change in object to the collaborative operation of the enterprises and the result of study has also obtained several conclusions to be provided as the reference mode when the enterprises implement ECM system and the related important topic for discussion when it is implemented and the enterprises can make appropriate adjustment and change accordingly.

A study of the Implementation of Collaborative Product Commerce System

Lin, Chih-Ming 29 July 2002 (has links)
Product is the core of an enterprise, and the major portion of its cost is determined in the design phase. By managing the design chain more effectively the enterprise can design the product to fit customer need, cut down cost and speed up time to market. All the benefits give rise to the implementation of Collaborative Product Commerce (CPC) system, whose purpose is to let all relevant parties including the focal company, customers, and suppliers to design, develop and manage the product in its whole product life cycle. In the literature of information technology (IT) and organizational change, the expected results of IT implementation may not happen, depending on the interaction between technology and organization. To illustrate this phenomenon, Adaptive Structuration Theory¡¦s (AST) is invoked to probe into the interaction between the CPC system and the organization. Our research findings indicated that the implementation of CPC system is influenced by the CPC¡¦s spirit, organizational environment, task features and group¡¦s internal structure. All these lead to variation in the appropriation process, which in turn has impact on the organizational performance. AST is helpful to explain the problems encountered in implementing CPC system. These include the improvement of product design and development process, the integration of CPC system and ERP system, the selection of consulting firms, and the user¡¦s attitudes. The CPC spirit is to achieve the optimized product design and development process. In the aspect of organizational environment, both executive support and openness of organizational culture are positive factors for implementation. In the aspect task feature, the relationship of the focal company with its downstream or upstream partners has significant impact on the task to be implemented by the CPC system, whether the appropriation process will go smoothly depends the reengineering effort made on the existing processes. In the aspect of group¡¦s internal structure, the experience, learning capability, and computer efficacy of user have positive impact on implementation. In addition, the consultants are also helpful to the implementation, which can be judged by their experiences, turnover rate, and domain knowledge. The appropriation process is evaluated by the consensus and the attitude of the user towards the CPC system, and these two factors all have positive impact on the implementation. The final conclusion renders that a prior established product data management in company with product design and development process reengineering will be helpful to the implementation of CPC system. In addition, the consultants interpret CPC¡¦s spirit. Therefore a partnership with the consultant company and the communication between the user and the consultant are helpful to the implementation of CPC system.

The Implementation PLM of Semiconductor Assembly Industry ¡V An Example of A Company

Tsung, Pei-Tzu 13 August 2008 (has links)
As the consumption trend has shifted to personal uniqueness, the traditional mass production of a single product has already been replaced by a small amount of various production to match consumption pattern. To meet challenge imposed by the market, manufacturers must change tactics and methods in their R&D activities. Consumers have already taken the high-quality products or services for granted, hoping to obtain the desired products or services that as soon as possible. The manufacturer expects to push new products or services to the market earlier than the competitors¡¦ move in order to gain extra profit margins. Higher price can be sold for a product pushed earlier to the market than a later product with the similar function. The products that lag behind in the market introduction will suffer lower prices or no profit. The manufacturer always wants to clear out the stock of existing products to control costs, and attempts to introduce new products or new services with more new functions before followers do. The purpose is to dominate the market and let followers not to enjoy profit margins. So, how to speed up the products¡¦ lifecycle should be the goal for enterprises to pursue. Recently, each enterprise emphasizes the core competencies, keep and strengthen the strong abilities of enterprises, and conducts outsourcing the less competitive products to those companies that are familiar with related manufacturing technologies. In the process a new product is developed or the modification for the product design has taken place. Questions arise as to : (1) how to transmit information to the person who must know as soon as possible? (2) how to guarantee the product information that the research personnel receive is the correct edition? Collaborative Product Commerce between the organizations will encounter more difficulties and challenges than the Collaborative Product Commerce within the organization. And this subject has already become serious challenges in the supply chain. The products function has grown more complicated, and a lot of unconfirmed factors exist in the development of new products. While the project developed carries on, customers¡¦ requirement, manufacturing technology and restriction of engineering ability, and the restriction of the supplier's engineering ability, may all influence the new product engineering. So while the new product development project carries on, because of these changes they will cause design modification or manufacturing operation modification, in order to enable development of the products to maintain integrally, and reach the goal of the project. So how to use PLM system to coordinate with among different functional organization department, and to coordinate inter-organization project team members, have become the main issues of this thesis. For Semiconductor Industry, Taiwan is the most important manufacture area of the world, from IC design, wafer fabrication, wafer probing, IC packing and final test, etc. Taiwan has a entire and strong supply chains. Count according to Dataquest, the global semiconductor assembly and testing industry subcontractor, Taiwan got the 43.7% market share in 2005, nearly have about 30% of leading disparity with No. two U.S.A. with scale of 6,641 million dollars, it is obvious Taiwan is the leading status of the industry in the whole world. This research takes case A Company as an example, and compares the new product development procedure before PLM implementation and after, including the project workflow, data access, information sharing, knowledge sharing, decision making and information security, in order to offer a reference model for the manufacturing industry especially semiconductor assembly and testing industry of Taiwan to implement PLM System.

A Study of the Implementation of Collaborative Product Commerce System in Taiwan

Chen, Kuan-Hua 28 January 2004 (has links)
In recent years, due to severe global market competition, increase of manpower costs and decrease in foreign trade, plus low-price labor costs from China and southeastern Asia countries (eg. Vietnam), all these factors enforce Taiwan manufacturing, such as motorcycle industry, moving their production factories to those countries. This phenomenon has been brought to Taiwan government¡¦s attention, and this crisis has encouraged our industrial circles to develop higher-level R&D and design center. Furthermore, the official department (eg. Industrial Development Bureau) also supplies enterprises with expenses support to conduct R&D and design. Within New Product Development (NPD) is one of the major subsidiary entries. Take Taiwan motorcycle industry as an example. To develop NPD is an essential competitive strategy for enterprise. On the one hand, this strategy has helped Taiwan motorcycle industry to be independent of technical domination from Japan; on the other hand, it has created differentiation in motorcycle industry and consolidated the foundation marching into international market. This is also what internal manufacture enterprises strive for. NPD process involves several stages. For example, in 1994 Cooper brought up product composition, initial evaluation, concept design, product development, product test, engineering trial production and limited quantity to market, these 7 stages, and NPD participant units or departments are quite a lot. For example, in motorcycle development process, participant units include merchandise plan, sales, R&D, manufacture, mold design, and quality control departments, and even parts supplier or motorcycle agent. This kind of collaborative development method has the advantages of putting heads together so as to get better results and cooperation. However, it remains existing problems with wasting time and efforts on inter-department interaction and manual data communication, and data accuracy (eg. version of design chart). To cope with the above problems, most enterprises are solving via existing IT system, such as simplex e-mail, more complex ERP (enterprise resources planning, ERP) or PDM (product data management, PDM). These systems have their own functions. E-mail focuses on communication; ERP integrates information of manufacture, human resources, finance, and marketing; PDM puts emphasis on engineering data management. In the viewpoint of NPD, these systems can only provides partial functions, but are incapable of support the requirements of entire collaborative process. For example, e-mail cannot supplies simultaneous communication; ERP lacks of design mold required by R&D department; PDM only has engineering data. If other departments need related data, they must develop other software to obtain. Because of swift progress in IT plus the cooperation demands in business operation among enterprises, departments and individuals, all these arouse attention on collaborative commerce, and it can also recover the disadvantages of e-mail, ERP or PDM while operating in NPD process. Collaborative commerce contains collaborative scheme, collaborative marketing, collaborative product commerce (or development) and collaborative service, these system classifications. Within them, collaborative product development binds NPD most. In current, the main manufacturers are PTC, HP and IBM. The merits of the system lie in effective controlling NPD process, constructing NPD operation standard, and accumulating experiences in new product design and manufacture. For example, in1995 Airbus in France had used PTC Windchill to conduct collaborative aircraft design. In 1999, there was Taiwan manufacturer under government¡¦s subsidy applying this system on new motorcycle model design. The main objective to introduce collaborative product development software is applying IT to support NPD process. IT introduction process is an important period for enterprises to identify whether it is successful or not, and the adaptation during the process is the key accordance to determine success or failure of IT. Therefore, some scholars discuss IT introduction process from adaptation point of view. For example, Leonard ¡V Barton¡]LB¡^¡]1988¡^addresses mutual adaptation mode between technology and organization to resolve misalignment during introduction process in technology (original IT specification), delivery system (training courses), performance criteria (impact upon activity). Susman et al.¡]2003¡^addresses that while using collaborative technology, the misalignments between technology and work, team and organization should be solved. DeSantics and Poole¡]1994¡^ bring up adaptive structuration theory¡]AST¡^. The theory emphasizes on appropiration in technology, work, organizational environment and group. The higher the appropiration is, the higher the decision performance will be. Tyre and Orlikowski¡]1994¡^deem the technology adaptation is not gradual and continuous, but highly discontiunous. They indicate that in adaptation discrepancy events will discontinuously occur. This event provides enterprise an opportunity to review the suitability of existing process or a method to modify present process. Although above researches have provided vital results, research result from Majchrzak et al.¡]2000¡^about new technology introduction process still cannot clearly describe all phenomena. Hence, they have discussed adaptation in project process via rocket design project and used collaborative technology (such as e-mail, data sharing or electric board) Majchrzak et al. has connected collaborative technology and NPD, but the research has discussed small and simple collaborative technology only (such as e-mail), but lacked of result of large and complex collaborative product development software. Meanwhile, although the result is the application of NPD, it does not provide the adaptation of each NPD stage (such as engineering trial manufacture). Furthermore, the mature experiences from western countries, such as Airbus in France, in introduction of collaborative product development software in NPD is worthy of consultation, but the specific situations in different countries should be taken into consideration. In Taiwan, cases which application of collaborative product development software supports NPD are still rare, but these introduction experiences are worthy of making thorough inquiry for other enterprises¡¦ reference. Therefore, the article has selected a case closed study of Taiwan manufacturing that introduced collaborative product development software and accompanied with related adaptation theory (such as LB mode, AST, discrepancy event, etc.) to thoroughly investigate adaptation conditions and result analysis before, in the middle of, and after introduction.
