Based on the basic process of new product development and the thought of the "stage-gate", a new network integrated model for new product development is designed. Structured by the three tiers of interaction with customers, development process, and databases set, this model not only takes on the application of the modern technology of computer, telecommunication network and database, but also reflects the ideal of centring on the customers, and the comprehensive utilization of the resources for new product development. This model can improve the process of new product development and shrink the cycle of new product development.
