Knowledge Transfer, Sharing, and Management System Based on Causality for Requirements Change Management

In software development, requirements changes cannot be avoided. Despite the importance of requirements change management, few studies in the literature concern requirements change knowledge management(RCKM). This study explored knowledge transfer and sharing of RCKM based on change cause analysis and the design of a knowledge management system(KMS) for change management. In this paper, previous research is discussed in three aspects: factors affecting knowledge transfer and sharing, methods to implement knowledge transfer and sharing, and the design of a KMS. After that, the results of a recent questionnaire are analyzed. Finally, this paper discusses the sources of tacit knowledge in the personnel management aspects of software development; the knowledge and the methods of knowledge transfer and sharing in the requirements change management process based on change cause analysis; the design of a data flowchart of repositories, and a prototype structure, logical model, and functional modules of RCKM systems. In conclusion, further study is suggested.
