5. DFMEA
5.1 Way of thinking for DFMEA
(1) DFMEA object product shall be assessed together with related system, sub-system and components.
(2) In the course of DFMEA, product design process shall be assisted through decreasing failure risk including unexpected results by implementing following items:
a) To assist objective assessment of design including functional requirements and alternative solution of design.
b) To assess initial design contents for requirements of manufacturing, assembling, packing, transportation, after sales service and recycling.
c) To increase probability that every potential failure mode and its effects for system and vehicle driving have been examined.
d) To provide additional information that is useful for planning of depthful and efficient design/development and its verification program.
e) To prepare list of potential failure modes ranked by level of effectiveness to “customer” and based on the list, to establish how to determine the priority of design/development and its verification program.
f) To provide documentation form for unsolved subjects that are used for suggesting risk reduction activities and following them up.
g) To provide reference information that is useful for analysis of problem in the market, assessment of design change and design up grating in future.
