Are system FMEA and cocept FMEA same?
The mechanics of performing the two are the same. The difference is in the intent and area of focus.

In a Concept FMEA, no design work has been done. Everything is very conceptual, and the focus is at the highest (yes, system level) of the design concept.

In a System FMEA, the system level design (or architectural design) has been initiated. The focus is still at the highest system level, but more information is available.

The two differ in the amount of detail available and the purpose. A Concept FMEA may be used to judge relative risk between alternative concepts or to guide the System design to mitigate risks. A System FMEA focuses on a single design and is used to guide the system design and design of subsystems to mitigate risk.

There is some overlap, yet also differences.

Concept FMEA is the first step in any Product or Process Design. First you are firmed on the Concept, the methodology adopted to produce a design, then one could go on to next step and look for weaknesses in a selected Product or Process Design. It is as simple as that. For Concept FMEA, normal tool used is PUGH METHOD:
