The method of quality cost management for the development process of aerospace product was studied. The overall management model of quality cost was proposed, in which the three-layer organizational structure, product development process and the management strategy of quality cost were combined. Furthermore, the method for quality cost management of each layer was presented in which the control granularity, process and object were taken into account. The control process was divided into three stages, control before the event, control during the event and control after the event. The analytic technique, tools and information were integrated, and the closed-loop control policy was applied. Finally, a quality cost management software system based on browser/server architecture was developed, which is called QQ-WebCost, and it has been implemented in an aerospace enterprise.
