PFMEA - RPN - Severity, Occurrence and Detection - Which one does not change?
Hi, there,
I had a job interview this afternoon, and they asked me such a question: Which one is not changed, among the the three items: severity, occurrence and detection?
Any comments or suggestions are welcome.
Roy

Just a little more......
The reason Severity doesn't change is that it takes a design change to affect the Severity rating which, ultimately, comes from the DFMEA. Things you do to monitor process paramaters will affect the Occurrence ratings and the inspections you perform (or don't perform) will affect the Detection ratings on the PFMEA.

Good additional information Bill. However, to clarify further: both the actions "monitoring" and "inspecting" affect detection only. The actions that affect occurrence are changing the process (e.g. error-proofing) or the design (e.g. opening up tolerances, changing geometry).
I agree that "severity" is the one that doesn't change in a PFMEA, unless the product design is changed.

Unfortunately I have not the original version of the AIAG manual, but one translated in Italian and this bothers me a lot!
(but why is it not distributed for free?)
So, many times its difficult for me to cite parts of the document.
Anyway I will try to referr to the manual.
It seems to me that for both (S) and (E) [points 12 and 15] the documents says that these values can be modified by changing either the process or the design.
Am I wrong?
If so, where is the difference?

severity does not change easily as seveity requires a design change
