About this Incident Post Mortem one pager template

Write up an outage the blameless way with this incident post mortem one pager template. It starts with the result in four numbers, such as minutes down, orders failed and time to notice, then walks the timeline minute by minute. The cause gets its own box in plain words, followed by what went well and what changes, each change with an owner. Engineering leads, site reliability teams and IT managers share it with the whole company after an incident, so leadership sees the impact and engineers see the fix. The same mistake is much harder to make twice.
