Answer to: Is ritualized confession a sign of a bad culture of failure?

I see this as a healthy sign. I think you are overthinking slightly. Benefits The team is made aware of the bug, nobody reads emails about it. So the team would not spend time chasing this bug, thinking it might be in their code. The team can learn not to make the mistake again. If they are not doing this, then you should ask what can we learn so as to not repeat the mistake. Emphasis on we not you. It difuses the management's blame game. They like finding a culprit to "yell" at. It gives advanced warning to support and marketing. If they are not part of it then Include the support, even if its just the support manager Don't include marketing, it's counter-productive. Instead send them a summary be email, with implications and time line to fix. From my own experince of managing dev team and support for many companies.
