Abstract: To deal with overlapping instances among sequential activities existing in concurrent product development process, the model to overlap product development with rework and iteration was presented based on information evolution of upstream activity and corresponding to sensitivity of downstream activity. And then it was applied to product development process with multiple IO using design structure matrix. Furthermore, some important parameters in the model such as information evolution and sensitivity were discussed and their impacts on overlapping were also revealed. In addition, potential risk might exist by using overlapping strategy. Eventually, implementation steps of the proposed approach were provided to illustrate the feasibility and effectiveness of the proposed method.
