Schema Development for Integrating Environment ofSE and EVM : Case Study

摘要

EVM(Earned Value Management) is applied to many large scale projects as one ofrnproject management techniques. But the measurements of the EV have been carried out byrnseparated process with Systems Engineering processes, in separated tool environments. Thisrnseparation caused the problem that EV does not show the exact value of the work accomplished.rnTo overcome this separation and to solve the problems, this paper suggests an integrated computerrnaided tool environment and processes.rnIn this research, we defined data elements needed for systems engineering and projectrnmanagement. Those elements are WP(Work Package), WP_DETAILED_PLAN,rnWP_PROCEED_DPLAN and SYSTEM REQ. WP is the decomposition of the WBS element andrnthe WP_DETAILED_PLAN contains PV information, the WP_PROCEED_DPLAN contains thernAC information and the SYSTEM REQ contains the requirements which the WP should satisfy.rnThese elements were implemented using computer aided systems engineering tool(Cradle?). Ifrnthis tool can be integrated with EVM tool, technical information related with EV can be tracedrnefficiently. This paper describes the integration concept mentioned above and the implementationrnof the concept.
