Did your quality instructors teach you to gather a team and brainstorm a problem to solve? That’s terribly bad advice. Use data to pinpoint the problem. Then, and only then do you know who should be on the root cause analysis.
I don’t know about you, but when I first got my quality training they said, “Get a team together and brainstorm a problem to solve and then go start trying to find the data, define the data, measure the data,” or something else. Now that’s the dumbest damn advice I ever got in quality training. I’ve looked at a lot of different training packages over the years and they still have all that same stupid stuff in there.
