Product development process modeling

The use of Concurrent Engineering and other modern methods of product development and maintenance require that a large number of time-overlapped "processes" be performed by many people. However, successfully describing and optimizing these processes are becoming even more difficult to achieve. The perspective of industrial process theory (the definition of process) and the perspective of process implementation (process transition; accumulation, and inter-operations between processes) are used to survey the method used to build one base mode(multi-view) process model,
