8D and the FMEA
Just another note on the 8D relationship to the FMEA, I am sitting in a facilitation of the Lean FMEA approach and one of the matrix items is the 8D inputs. The past failures is one item in the 3 cases for doing an FMEA.
The FMEA and more appropriately the Lean design Matrix for the FMEA family should always be present for the 8D development. The brainstormed causes already present in the FMEA can shorten the root cause activity by at least one and possibly two layers of the “WHY” discussions.
Keep in mind that the FMEA will be updated at D7 (prevention) or if done most efficiently in real time at D2 and D4 as the 8D progresses.
