Design FMEA (DFMEA) Introduction to Design Failure Mode and Effects Analysis (DFMEA) When first envisioned, Design Failure Mode and Effects Analysis (DFMEA) considered potential failures modes and their causes. It was first used in rocket science. Initially, the rocket development process in the 1950’s did not go well. The complexity and difficulty of the task resulted in many catastrophic failures.  Root Cause Analysis (RCA)  was used to investigate these failures but had inconclusive results. Rocket failures are often explosive with no evidence of the root cause remaining. Design FMEA provided the rocket scientists with a platform to prevent failure. A similar platform is used today in many industries to identify risks, take counter measures and prevent failures. DFMEA has had a profound impact, improving safety and performance on products we use every day. What is Design Failure Mode and Effects Analysis (DFMEA) DFMEA is a methodical approach used ...
