The analysis leads design(ALD) method was advanced to summarize the key concepts and analyze the essential ideas from the iterative phenomena during the product design process. The concepts of design information(DI), design activity(DA), design model(DM), design file(DF) and analysis leads design flow(ALDF) in the ALD method were defined. As self-driven design flow, ALDF was the core concept of the ALD method. The process of establishing the ALDF was the ALD method. The design information and the design activity of the ALD flow were elaborated. The serial and parallel methods to order the design activity of the ALDF were emphasized, of which the function of time cost was given. The product design plan was optimized by the ALDF to improve the design quality and efficiency. Some key techniques of the ALD method were resolved, and the ALD method was exemplified by the structure design of the turbo-jet blade. And the conditions, the self-driven design flow, the diagram of geometry variables and performance variables of the example were given.
