Blameless Incident Postmortem Template for Notion

A free Notion system for engineering teams to run blameless postmortems — and actually finish the action items.

Why I built it

Most postmortems get written, filed, and forgotten. The document looks complete, but the action items quietly die: nobody owns them, nobody checks them, and the same incident comes back a few months later.

I built this from my own reliability work. The core idea is simple: a postmortem is not done when the document is written. It is done when the actions are done. So the template tracks actions as first-class citizens, with owners, due dates, and an overdue view that makes unfinished work impossible to ignore.

What’s inside

• Incidents database — every incident in one place, with severity, status, timeline, and a duration that computes itself from start and end times.
• Action Items database — linked both ways to its incident, so you can see at a glance what each incident still owes you.
• Progress you can see — each incident rolls up the percentage of its actions that are done, and an Overdue view flags anything past its due date while still in progress.
• Views that match the workflow — incidents by status board, recent incidents, by severity, and calendar; actions by open, overdue, and owner.
• Blameless page template — timeline, contributing factors, 5 Whys, and a rule that every contributing factor gets a prevention action, not just a description.
• Severity guide — SEV1 (critical, system-wide outage) through SEV4 (low, internal), with when to page and when a postmortem is required.
• Quick-start guide — set it up and write your first postmortem in minutes.
• Worked example — a full SEV2 postmortem (checkout API p99 latency spike: a deploy added an N+1 query, p99 went from 300ms to 4.2s, mitigated by feature flag), with four action items at 75% done, including one deliberately overdue example so you can see the Overdue view working.

How to use it

Get it free on Gumroad (pay what you want), duplicate it into your own Notion workspace, and it is yours. No setup beyond that: add an incident, fill in the template, and let the action items carry the follow-through.
