There has been some research on the theory of QFD (Quality Function Deployment) and FMEA (Failure Modes and Effect Analysis) recently, but little work to the integrated system of QFD and FMEA development. This paper analyses the technical difficulties of realization of QFD and proposes away using computer-supported collaborative work to develop the integrated system of QFD and FMEA and how to do it. The way can make the system more efficient and more suitable to new requirements of networked manufacturing enterprise. The same time, prototype system of the integrated system is developed by comprehensively application of Java、JSP、JavaServlet, the open World Wide Web platforms of which enhances the communication function, improves the group cooperation and shorts the development time. The system is verified reasonably and reliably through the example of QFD analysis of some automobile.
