Recently, the concept of Mizen Boushi (reliability problem prevention) has been applied in automotive development as a tool to refine drawings to the greatest completion possible by the prototype stage. In this point of view, we are promoting a quality innovation process, "GD^3" that means "Good Design", "Good Discussion" and "Good Design Review". The process utilizes creative FMEA, FTA and a System Design Review. These tools focus attention on the many potential problems that could occur due to a change in design or environment. The System Design Review is especially useful to examine potential failure modes, root causes, part drawings and prototype part designs. This is followed by a Design Review Based on Failure Mode (DRBFM method for short), as a tool to guide discussion. In this way, it is possible to generate the best approach to handling design, evaluation, and production concerns. This paper will introduce some of the specific ways that this creative process is currently used in development as a tool to prevent reliability problems.

This paper propose the concept of hidden problem visualization and measures method in design stage with system DRBFM (Design Review Based on Failure Mode). The potential problem in the design stage involves unnoticed problems and misunderstood problems. The unnoticed problem can be visualized by the work flow of system DRBFM which takes into account the hierarchical structure of products. The misunderstood problems is also visualized by discussions in system DRBFM, containing the collation of concerning design with Design Regulation and the verification by Professional adviser based on Attention in operation. Afterwards, the total of misunderstanding problems reflects in improvement of Attention in operation. By the above concept, system DRBFM can posess two functions. The one is as for the useful tool of OJT (On the Job Training) which educates designer who has misunderstood or oversighted immediately by Professional adviser. The other is the construction of precationary measures organization with system DRBFM, Professional adviser, Design Regulation and its Attention in operation. To display the use of thease functions, the proposed concept is applied to design change of hair drier. The application example can display the role of all part of system DRBFM intelligibly.

The concept of Mizen Boushi(reliability problem prevention) has been applied in automotive development. Recently, we are promoting a quality innovation process, "GD3" that means "Good Design", "Good Discussion" and "Good Design Review". In the first paper, it was presented to utilize a System Design Review during development, in which we discuss potential failure modes, root causes and examine parts drawing and prototype parts design with the DRBFM(Design Review Based on Failure Mode) method. This paper will introduce that we completed the System DRBFM as a universal Mizen Boushi method, which can be utilized for discussions from a complex/complicated system to elements with hierarchy block diagrams of product and management.
