┌─────────────────────────────────────────────────────────────────┐

│  Phase 1: TRIAGE                                                  │
│  ✓ Assess severity (SEV1-4)                                     │
│  ✓ Identify affected systems and users                          │
│  ✓ Assign roles (IC, comms, responders)                         │
│                                                                    │
│  Phase 2: COMMUNICATE                                              │
│  ✓ Draft internal status update                                  │
│  ✓ Draft customer communication (if needed)                     │
│  ✓ Set up war room and cadence                                   │

│  Phase 3: MITIGATE                                                 │
│  ✓ Document mitigation steps taken                               │

If Connectors Available

If ~~monitoring is connected:

• Pull alert details and metrics
• Show graphs of affected metrics

If ~~incident management is connected:

• Create or update incident in PagerDuty/Opsgenie
• Page on-call responders

If ~~chat is connected:

• Post status updates to incident channel
• Create war room channel

Tips

1. Start writing immediately — Don't wait for complete information. Update as you learn more.
2. Keep updates factual — What we know, what we've done, what's next. No speculation.
3. Postmortems are blameless — Focus on systems and processes, not individuals.
