Abstract: Conceptual process planning is one of important activities in the early product development stage. However, detailed product information couldn't be obtained so that it was difficult to carry out conceptual process planning. Therefore, key characteristics were proposed to express incomplete product information with rough-granularity, and to support productability analysis and key process planning in the course of conceptual process planning. The key characteristics were defined. Classification, flow-down decomposition and transfer principles of key characteristics were discussed. Process and approaches of identifying key characteristics in the early stage of product development were proposed including three steps: design requirement acquisition, design requirement and characteristics mapping, and key characteristics decision. Finally, the wing design for winged missile was used to verify the proposed process and approaches.

Key words: key characteristics, identification, mapping, conceptual process planning, concurrent engineering
