Incident Postmortem Blameless Workflow
Conduct a blameless postmortem after an incident to identify root causes, action items, and systemic improvements.
Objective
Run a blameless postmortem to learn from incidents and prevent recurrence.
Environment
- A recently resolved incident with timeline and impact
- Participants from all involved teams
- A postmortem template
Steps
1. Gather timeline
Collect the incident timeline: detection, response, mitigation, and resolution.
Expected state: A complete incident timeline is assembled.
2. Identify root causes
Analyze the timeline to identify contributing factors and root causes without blame.
Expected state: Root causes are identified and documented.
3. Generate action items
Create specific, owned, and dated action items to prevent recurrence.
Expected state: Action items are assigned with owners and due dates.
4. Review with team
Present the postmortem to the team for feedback and additional insights.
Expected state: The postmortem is reviewed and refined with the team.
5. Track to completion
Add action items to the tracking system and monitor progress to completion.
Expected state: All action items are tracked until resolved.
Decision points
Public or internal postmortem?
- Public for transparency
- Internal for privacy
Share internally by default; publish publicly for major incidents to build trust.
Expected outcome
A blameless postmortem is completed with root causes, action items, and a tracking plan.
Verification
Verify all action items have owners and due dates; confirm the postmortem is shared with the team.
Cleanup
No cleanup needed; postmortems should be archived for future reference.
Blameless culture finds systemic issues
When people feel safe reporting mistakes, the organization can fix the system instead of the people.
Implementation Notes
This workflow provides a structured approach to ensure consistent results across team members and environments.
Common Pitfalls
Skipping verification steps or rushing through the process can lead to incomplete results. Always follow each step in order and verify before proceeding.
