Audience member asks what company/team-level processes (post-mortems, documentation, requiring PR authors to reproduce bugs) Rząsa's teams have used. Answer: post-mortems are helpful but require cultural work — in a toxic culture they become blame games, while a healthy team can write honest 'crime-novel' post-mortems everyone reads. In a small company, a Slack note saying 'we screwed up, here's what happened' can be enough. Also shares a surprising lesson: one post-mortem he watched described the problem and immediate actions but deliberately omitted a long-term fix, because the manager judged the heavy fix would be too costly for a problem unlikely to recur — a valid trade-off.
