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.
