Abstract: While the implement of major sciense and technology programs brings out a new challenge for the practice of innovative governance, the techniques and ideas of modularity innovation can provide an improtant referrence for the practice. The techniques and measures applied to the process of defense acquisition in U.S are analyzed. with the view of modularity innovation management and the enlightening role of standard in the design of modularity and knowledge manangement is put forward. The performance machanism of techniques is discussed, such as Work Breakdown Structure(WBS), parallel decision-making model, and stage-gate control, etc. acted on the process of modularity innovation. Finally, a design model for the whole process of the innovative governance in the defense acquisition.
