Often focus is on DFMEA and PFMEA. Prior to these there is the SystemFMEA, though.
Wonder if anyone actually do SFMEA's, focus on this topic is rather vague in the QS manual as well.
I tried a couple of times to produce a SFMEA. My approach was to list costumer requirements one by one, and then identify possible sub-system causes for the systems failure mode and rank them accordingly. In this way I could already identify somecritical and non-critical requirements, before the next step (DFMEA-PFMEA).
I find it difficult to steer clear of a detailed DFMEA during this stage and therefore get a "muddy" transition to the DFMEA.
Anyone who has input on difference and handling of SFMEA versus DFMEA?
