39、and to enhance the quality of digital product and process descriptions. Simultaneous engineering in product development and manufacturing planning and intensive cooperation between the various divisions within a company and with external partners are key factors for success in this context. One of t
40、he key challenges to be surmounted when shortening development times and ramp-up times in series manufacturing is to successfully and rapidly implement the changes which occur dur-ing these phases in a joint effort with partners from the fields of development, planning and manufacturing. Some factor
41、s which regularly motivate the wish to initiate changes include: Legislative changes Changes to market conditions or the competitive situation Internal inadequacies in development, planning or manufacturing Quality or safety problems Exploitation of additional optimization potential The desire to ma
42、ke changes also necessitates corresponding changes to the cross-company engineering change management processes between the partners, suppliers and service providers to achieve greater dynamism and flexibility. Thus, mastery of engineering change management processes is increasingly becoming a cruci
43、al factor in the success of coopera-tive ventures in the automotive industry. Suppliers are today integrated into the development and planning process at an early stage. Differences which result from the nature of the part-ners and the projects in which they are involved mean that it is a challengin
44、g task to integrate partners into engineering change management. Small changes can, however, often have a significant impact on costs, processes, and development and manufacturing times. This means that standards and recommendations for structuring and implementing cross-company engineering change m
45、anagement processes and engineering change management data right down to the level of defining company-specific interfaces are indispensable if inte-gration is to be efficient. According to estimates of the ECM project group, cost savings of up to around 40% can be expected as a result of reducing t
46、he times involved in retrieval, coor-dination and processing during the course of cross-partner engineering change management processes. Harmonization of private (i.e. partner-specific) ECM processes is one key contribution to-wards exploiting the potential for improvement during development and whe
47、n starting up se-ries manufacturing. This current recommendation is based on the requirements and experi-ences of the partners in the joint SASIG ECM workgroup. This recommendation has been validated by means of pilot projects in the companies involved. ECM Recommendation Part 0 ECM Abstract 2 Repla
48、ces: Version 1.0 Version 2.0, Issued: Aug. 2009 1.2 Objectives of the recommendation The objective of the recommendation is to provide support for ECM processes with respect to the communication of change data between customers and suppliers. Use of the recom-mendation allows more efficient integrat
