What is the difference between a Concept FMEA and a System FMEA?

What is the diffrence between ConceptFMEA & SystemFMEA?

[Marc]

This is not meant to be sarcastic, but one is on a system and one is on a concept. If you think about the differences, it should become clear.

Take a concept such as windshield wipers which turn on automatically when it rains. You FMEA the concept, in part for feasibility.

Then let's say you decide to do it and you design a system (combination of mechanical and electronic) and you then FMEA that.

Thank you for your response Mr.smith
But When I studied these subjects it seems that there is'nt any defference between them.even all of definition in the concept and system FMEA is the same.

Do you have a perfect reference to these type of FMEA?

Nothing is perfect. A FMEA is a FMEA, it is a process of determining possible pepples in the road ahead. It really doesn't matter if it is a design, process, system, concept etc... the tools are basically the same.

You used the term feasibility, we all do it but when you come down to it the feasibility and FMEA serve the same purpose. Don't get caught up in symantics.

Just my lowly opinion.

Good Luck!

Is everyone aware that the 3rd edition on the fmea handbook has been released? I ordered mine yesterday.
Al, I wouldn't worry about what you call your fmea as long as you are doing them. And you can do them on anything. If you have a customer request to do concept fmeas then by all means call your fmeas concept fmeas.

Basically, an FMEA is a Risk Analysis tool.

hello!
I had the same problem in the past when I found the for the fist time the Concept FMEA in a Ford manual (FMEA version 31, section 3);it was decide to use:
-Concept FMEA: in the feasibility phase for the new or updated platforms; only potential customer are considered
-system FMEA: at the early phase of the development of a new system; the requirements have been fixed nd there is a nomination letter from the Customer
