How It Works
┌─────────────────────────────────────────────────────────────────┐
│ INCIDENT RESPONSE │
├─────────────────────────────────────────────────────────────────┤
│ 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 │
│ ✓ Track timeline of events │
│ ✓ Confirm resolution │
│ │
│ Phase 4: POSTMORTEM │
│ ✓ Blameless postmortem document │
│ ✓ Timeline reconstruction │
│ ✓ Root cause analysis (5 whys) │
│ ✓ Action items with owners │

Severity Classification
| Level | Criteria | Response Time |
|---|---|---|
| SEV1 | Service down, all users affected | Immediate, all-hands |
| SEV2 | Major feature degraded, many users affected | Within 15 min |
| SEV3 | Minor feature issue, some users affected | Within 1 hour |
| SEV4 | Cosmetic or low-impact issue | Next business day |

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