One of the best things I learned from working at Google is the practice of blame-free postmortems. When something goes wrong, you wait until the dust settles, then write a report analyzing what happened. The report explains how the problem occurred and defines concrete steps the team can take to mitigate the problem in the future. I saw a good opportunity for a postmortem last week. Work officially completed on a bounty-funded project to integrate Sia support into Minio, but it took several months longer than expected and went through multiple large-scale rewrites.
