What Is PFMEA?

PFMEA (Process Failure Mode and Effects Analysis) is a structured approach that assigns quality risk levels to each step in a process (manufacturing or transactional). PFMEA is a powerful prevention tool, since it does not wait for defects to occur, but rather anticipates them and implements countermeasures ahead of time.

15/1/2002 · DFMEA deals with potential mode of failure for all of the design characteristics (they were established before the design work started) – it is sort of a gate for the design. IMHO the DFMEA is much more important than PFMEA – only because once the design is set your level of quality is set as well based on: operator skills, machinery, MSA, etc.
