Yes, we had a tooling design and it was going to fail because the angles and mechanisms were not right. My boss overruled me, under protest, and we built it how the customer wanted it with no changes.
It failed in production.
There was a big meeting with everyone upset. I said I told you! And tried to reexplain why it doesnt work. They denied knowing about the issues previously.
Thankfully the president stepped in and said, I was in the initial meeting and remember you warning of the potential failure. Then everyone shut up.
We redid everything my way.
