Study on Engineering Change Management

In this paper, we analyzed all the factors and their relations related to engineering change management. Such factors as the changing process, the management of product data and suppliers of parts are discussed in detail. After analyzing the relation between engineering change management and product data management, the object of engineering change management and its difference from data management and process management is put forward. The basic aim of engineering change management is to develop change ratio of products with lower cost and less error. It is argued in this thesis that effective product data management is fundamental to engineering change management. A model of implementation of engineering change management is provided according to the previous analysis. Finally, the implementation of this model in Jiangling Motor Corp. is given as an example.
