When something goes wrong, the instinct is to find the person responsible. In my experience, that almost never fixes anything. The same mistake comes back with a different name attached to it.
I treat every mistake as one of two things: a process gap or a training gap. Either the process allowed the error, or the person was never properly shown how to avoid it. Both are fixable, and neither requires blame.
Once you know the root cause, error-proof it. Lean calls this poka-yoke: design the step so the mistake is hard or impossible to make. A part that only fits one way. A checklist built into the form. A visual cue right where the decision happens.
Fix the process, not the person, and the mistake stays fixed.
Do this consistently and something bigger happens. People stop hiding problems, because reporting one leads to a fix instead of a reprimand. That's the beginning of a real continuous improvement culture.
