I'm in QA, and this is something like what I've been doing with running pre-mortems. Basically, at the project planning stage, I get everyone together and ask how this shit is going to blown up in our faces. What are all the scenarios that are complete failures. Then a few weeks before a release, I do the same thing. It's amazing the issues this catches from the cross team approach. For instance, something that the product manager was worried about, they never brought up because they assumed engineering knew about it was covered, but in reality, they had no idea that was important. Or with two engineering teams, or DevOps etc. Normally we have more than a dozen action items out of these meetings.
