Blameless postmortems are useless without this one habit

Head of Infrastructure

The blameless postmortem is standard practice now, and that's progress. But too many retros end with a document nobody reads and action items nobody owns.

Our rule: every postmortem action item goes into the same tracker as production bugs, with an owner and a severity. Unresolved items block the next quarterly planning.

Close the loop

Six months in, our repeat-incident rate dropped by 70%. Not because the postmortems got smarter — because the follow-through became non-optional.

Kindness gets people to tell the truth about what broke. Accountability is what keeps it from breaking twice.
