Incident Lifecycle
The end-to-end journey of an incident from the moment it occurs until the post-incident review is completed.
From Chaos to Closure
Every incident, whether a minor bug or a major outage, follows the same lifecycle. Understanding these stages helps teams move faster.
The 5 Stages
- Detection: The system breaks. Alerts fire. (Metric: MTTD).
- Triage: Impact is assessed. Responders are paged. (Metric: MTTA).
- Response: The team investigates, communicates, and mitigates.
- Resolution: Service is restored. (Metric: MTTR).
- Post-Mortem: The team learns why it happened and prevents recurrence.
ExSaaS API Outage
“API goes down at 2 AM. Detected in 2 min, triaged in 5 min, team responded in 15 min. Workaround restored service in 45 min. Root cause found next day. Post-mortem completed within 48 hours with action items.”
Impact
Reduced MTTR from 4 hours to 45 minutes over 6 months
Resolution
Implemented circuit breaker pattern to prevent cascade failures
Why Incident Lifecycle Matters
Provides a structured framework so teams know "what comes next".
Ensures no step (like the Post-Mortem) is skipped.
Common Pitfalls
Declaring resolution too early
Only declare resolution when the fix is verified in production. False closures damage customer trust.
Skipping post-mortem for "minor" incidents
Conduct lightweight post-mortems for all incidents. Small issues often indicate systemic problems.
