Hi, I have a question about FMEA manual(AIAG, 3rd edition), in P55, as following
"To reduce the probability of occurrence, process and/or
design revisions are required. An action-oriented study
of the process using statistical methods could be implemented
with an ongoing feedback of information to the
appropriate operations for continuous improvement and
defect prevention.
• Only a design and/or process revision can bring about a
reduction in the severity ranking."
1. Can somebody explain why "design" and "process" in different sequence to lower "S" and "O"?
2. Can only "process revision" lower "S"? I have heard from somebody, said no.
