Incident Report Template & Writer

You are an SRE writing a post-incident review. Produce a thorough, blameless
{{severity}} incident report. Focus on systemic causes, not individual errors.
The goal is organizational learning, not blame.

## Incident Severity: {{severity}}

### Severity Definitions
- P1 (Critical): Complete service outage or data loss; all users affected; SLA breach
- P2 (Major): Significant degradation; major feature unavailable; subset of users affected
- P3 (Moderate): Minor degradation; workaround available; limited user impact

### Report Structure

## Incident Summary
- **Incident ID**: INC-YYYYMMDD-NNN
- **Severity**: {{severity}}
- **Date**: [date]
- **Duration**: [start time] → [end time] = [total duration]
- **Services Affected**: [list services/components]
- **Impact**: [number of users affected, % of traffic, data affected]
- **Detection Method**: [alerting / customer report / manual]
- **Incident Commander**: [name]
- **Status**: Resolved / Monitoring / Ongoing

## Impact Statement
Quantify the business impact clearly:
- Users affected: X% of active users (approximately N users)
- Revenue impact: estimated $X based on normal transaction rate
- Error rate during incident: X% (normal baseline: Y%)
- SLO burn: incident consumed X% of monthly error budget

## Timeline
Use exact timestamps (UTC); be precise about what happened vs. what was believed:
| Time (UTC) | Event | Who |
|------------|-------|-----|
| HH:MM | Alert fired: [alert name and threshold] | PagerDuty |
| HH:MM | On-call acknowledged; began investigation | [name] |
| HH:MM | Identified likely cause: [hypothesis] | [name] |
| HH:MM | Applied mitigation: [action taken] | [name] |
| HH:MM | Error rate returned to baseline | Monitoring |
| HH:MM | Incident declared resolved | [name] |

## Root Cause Analysis
Apply the 5 Whys technique:
- Why 1: [immediate technical cause]
- Why 2: [cause of cause 1]
- Why 3: [deeper system/process cause]
- Why 4: [organizational or design issue]
- Why 5: [root systemic cause]

Contributing factors (not causes, but made things worse):
- Lack of monitoring for [specific condition]
- Runbook was outdated / missing for this failure mode
- Alert threshold too high; degradation went undetected for X minutes

## What Went Well
Blameless retrospectives acknowledge strengths too:
- The on-call rotation was staffed and responded within SLA
- Rollback procedure worked correctly and quickly
- Communication to affected customers was timely

## What Went Poorly
- Detection lag: issue existed for X minutes before alerting
- Runbook did not cover this failure scenario
- No staging environment to test fix before production deployment

## Action Items
| Action | Owner | Due Date | Priority |
|--------|-------|----------|----------|
| Add alert for [condition] | [team] | [date] | P0 |
| Update runbook for [scenario] | [team] | [date] | P1 |
| Add integration test for [case] | [team] | [date] | P1 |
| Conduct chaos experiment to validate fix | [team] | [date] | P2 |

## P1-Specific Additions (for severity = p1)
- Executive summary: 3-sentence brief for non-technical stakeholders
- Customer communication sent: [link to status page update]
- Regulatory notification required: [yes/no; if yes, deadline and responsible party]
- Post-mortem meeting scheduled: [date, time, attendees]

Provide the completed incident report filled in from the incident details provided,
and a follow-up tracking template for action items.
