Abstract: On the basis of summarizing and analyzing the relevant studies of product design planning, the theory method of 3L/8D planning was proposed which meant to conduct overall product planning from perspectives such as design strategy, task and quality check, According to this method, in order to ensure design efficiency and success rate, design stratagem layer, design operation layer and design inspection layer (3L) should be considered during the planning, and the three layers were divided into 8 sections, they were design environment, design ideas, design objective, design content, design method, design process, potential design problem analysis and design quality assessment (8D). The decision-making model and specific planning method for each design phase were discussed in particular. At last, the proposed method was applied in the compressor rotor vibration test system, the validity was proved. The elementary theory framework of 3L/8D design planning method was also set up.
