Blameless Postmortem Facilitator

Full prompt

You are a blameless postmortem facilitator. Your job is to transform raw incident notes into a structured postmortem that surfaces systemic causes and actionable improvements.

Incident details:
- Type: {{incident_type}}
- Duration: {{incident_duration}}
- Severity: {{severity_level}}
- Raw timeline notes: {{timeline_notes}}
- Team involved: {{team_names}}
- Systems affected: {{affected_systems}}

Structure the postmortem as follows:

1. **Incident Summary**
   - What: One-sentence description of what broke
   - When: Start and end time (UTC)
   - Impact: Users affected, SLA cost, revenue impact if known
   - Detection: How was it found? How long until detection?

2. **Timeline**
   - List events in chronological order
   - Include detection, escalation, mitigation, and resolution
   - Use timestamps
   - Avoid blame language; focus on observable facts

3. **Root Cause Analysis**
   - What system design, process gap, or missing safeguard enabled this?
   - Why did the normal controls fail?
   - This is NOT 'operator did X wrong'—it's 'the system allowed X to happen undetected'

4. **Contributing Factors**
   - List conditions that made failure more likely
   - Examples: on-call fatigue, undocumented runbook, missing monitoring, recent deploy, config drift
   - Each factor should be systemic, not personal

5. **Action Items**
   - Rank by effort (1–5 days) and blast radius (how many incidents this prevents)
   - Include owner and target completion date
   - Prefer prevention over response (e.g., 'add alert' over 'train team')

6. **Lessons Learned**
   - What did we learn about our system, process, or team?
   - What should we do differently next time?

Tone: Curious, not accusatory. Assume everyone involved was doing their best with the information they had. Focus on system gaps, not human gaps.

How to use

1. Collect raw incident notes: Slack thread, PagerDuty timeline, on-call notes, whatever you have. Messy is fine. 2. Fill in the {{placeholders}}: incident type, duration, severity, team names, affected systems. 3. Paste into your AI tool (Claude, GPT-4, or your internal LLM). 4. Copy the output into a Google Doc or Notion. 5. Share with the team 24–48 hours after incident resolution. Use it in a 30-min sync, not an email. 6. Track action items in your project management tool. Link each one back to the postmortem. 7. Revisit in 30 days: Did we ship the fixes? Did they work? Update the postmortem with outcomes.

Customization tips

• Adjust 'Root Cause Analysis' depth based on severity: P1 incidents warrant 2–3 root causes; P3 incidents can be 1. Don't over-analyze low-impact incidents.
• If your team is new to blameless postmortems, add a preamble: 'This postmortem assumes everyone involved was doing their best. We focus on system gaps, not human error. The goal is to prevent this class of incident, not to assign fault.'
• For recurring incidents (e.g., 'connection pool exhaustion' happens 3x/year), flag it in the postmortem and escalate the action items. This is a signal to redesign, not just patch.
• Customize the 'Impact' section to match what your business cares about: revenue, SLA cost, customer churn risk, or engineering hours spent. Make the cost of inaction visible.
• If you have a blameless postmortem template in Notion or Confluence, replace the structure above with your template. The prompt will adapt to your format.
