[A followup to Squishy Human Fails At Task]
Once you get the team used to "people don't fail, processes fail", you're still only halfway there.
The next thing that happens, with the best will in the world, is that people report failures and add the sentence "we'll change the process so that this doesn't happen again", as a sort of get-out-of-jail-free-card.
But it's not a card. It's a rock hammer. Process change is the tool, but you still have to do the work.
And, like in debugging code, if you don't know why something failed, you don't yet know why its replacement will also fail - but you're doomed to find out.
