PURPOSE OF DFMEA (DESIGN FAILURE MODE EFFECTS ANALYSIS). Identify , quantify , and reduce design risk (especially for critical systems) Provide a traceable document for making design decisions Prioritize which design activities to pursue next
(This is also normally required by a customer)
(linked to the effect of the failure)1 = device operable with minor loss of functionality 2 = device operable with significant loss of functionality 3 = device damaged and inoperable, but repair is possible 4 = device damaged beyond repair 5 = failure causes moderate to severe operator injury
Revise your DFMEA frequently!
Include documentation of your results!
