Schema Development for Integrating Environment of SE and EVM : Case Study

Abstract

AbstractEVM(Earned Value Management) is applied to many large scale projects as one of project management techniques. But the measurements of the EV have been carried out by separated process with Systems Engineering processes, in separated tool environments. This separation caused the problem that EV does not show the exact value of the work accomplished. To overcome this separation and to solve the problems, this paper suggests an integrated computer aided tool environment and processes.In this research, we defined data elements needed for systems engineering and project management. Those elements are WP(Work Package), WP_DETAILED_PLAN, WP_PROCEED_DPLAN and SYSTEM REQ. WP is the decomposition of the WBS element and the WP_DETAILED_PLAN contains PV information, the WP_PROCEED_DPLAN contains the AC information and the SYSTEM REQ contains the requirements which the WP should satisfy.These elements were implemented using computer aided systems engineering tool(Cradle®). If this tool can be integrated with EVM tool, technical information related with EV can be traced efficiently. This paper describes the integration concept mentioned above and the implementation of the concept.
