The difference and relationship of systems engineering and project management were discussed. It is concluded that the complex product development requirs the combination of systems engineering and project management. Therefore
a WBS (Work Breakdown Structure) model
PDA-WBS
is proposed to satisfy this requirement. The characteristic of the WBS is discussed
and a DWBS template which coordinates with the characteristic of the systems engineering is presented. Finally
a software framework to implementing the presented WBS is introduced.
