The traditional series working mode can not make the outcome of product design process verified by activities of manufacturing domain in time, and the manufacturing process can not be executed concurrently. The purpose of this paper is to develop a method to solve the problem mentioned above. The connotation of the collaboration between design and manufacturing is studied firstly, and then the design state maturity model (DSMM) is proposed in this paper. Six levels of maturity are defined in this model, and every level can support the collaboration between design and manufacturing in different degree. Based on the design information required in the manufacturing process, the information included in each level is studied and particularized. Finally, the DSMM-based work process of collaboration between design and manufacturing is studied.
