A Process Optimization Method Based on Process Performance Models

Software process simulation and optimization hold out the promise of improving software development process and supporting CMMI implementation. This paper first brings up a two layer process simulation model (T-PSM). The higher level is called process model which expresses the structure of the model. The lower level contains a behavior model and a computation model. The behavior model describes the simulation behavior of a process and the computation model enables activities in processes with computation capability. Then a process optimization method is proposed by integrating T-PSM with organization's process performance models to obtain simulation data. The process performance models represent the performance of the organizational processes and they are built by organization's historical data. Finally, the system architecture of this method is presented.
