Incident Management Overview
Incident management is how you handle outages and degradation in a consistent, humane way.
Detecting means alerts and observability that surface real issues without drowning the team in noise—so you know when something’s wrong and how bad it is.
Responding means clear roles (who’s on call, who escalates), severity levels, communication (internal and, when needed, external), and runbooks or playbooks so people can act quickly instead of guessing.
The part that often gets shortchanged is learning.
After the incident is resolved, blameless postmortems and retrospectives turn “what went wrong” into “what we’ll do differently”—process changes, better detection, or design improvements that reduce the chance or impact of similar incidents.
This section is about the practices and processes that help you detect, respond, and learn so your systems and teams get better over time.
- Incident lifecycle — Phases 0–7, roles, and mnemonic for running incidents.
- Severity and Classification — How to classify incidents, when to declare, and when to convene a full response.
- On-Call and Escalation — On-call rotation models, escalation paths, and when to escalate.
- Runbooks and Playbooks — What they are, what makes them effective, and connection to game-days.
- Communicating During Incidents — Internal and external updates, cadence, and the Communications Lead role.
- Post-incident review — 10-step post-mortem checklist, principles, and quick summary template.
- Production Readiness — Readiness checklists, reliability reviews, service ownership, on-call maturity, risk assessments.
- Toil and Automation — Identifying and measuring toil, automation ROI, reducing operational burden.
