Engineering change management on the web

Engineering changes (ECs) are changes and/or modifications in forms, fits, functions, materials, dimensions, etc. of products and constituent components. ECs usually induce a series of downstream changes. Multiple disciplines and responsibilities are therefore involved in managing ECs. Previous investigations conducted by both authors and other researches have shown that paper-based and standalone computerized EC management (ECM) systems are limited in supporting such intensive teamwork and close communication. This paper proposes to establish a web-based ECM framework that supports ECM procedures and activities, clarifies responsibilities, and provides associated documents. A web-based ECM system is able to provide better information sharing, simultaneous data access and processing, and more prompt communication and feedback. The amount of paperwork and the throughout time of managing ECs are significantly reduced while the effectiveness and efficiency are substantially improved. This paper focuses on discussing the issues of design, development and implementation of this prototype system.
