FMEA: What Value Is It Bringing You?

I have had the pleasure of working in a number of unique engineering environments and for the most part they all performed Failure Modes and Effects Analysis (FMEA). Whether it was a Systems FMEA (SFMEA), Design FMEA (DFMEA), Process FMEA (PFMEA), or Failure Modes, Effects, and Criticality Analysis (FMECA), they …

Box, the English statistician, famously observed, “All models are wrong, but some are useful.” He further clarified that idea with this expansion, “Remember …
