Incident Management
Incident management is the structured process a team follows to detect, respond to, resolve, and learn from unplanned disruptions to a service — from initial alert through resolution and a follow-up review.

Incident management is the structured process a team follows to detect, respond to, resolve, and learn from unplanned disruptions to a service — from initial alert through resolution and a follow-up review.
Overview
When a service goes down or degrades, incident management is what turns chaos into a repeatable process: someone gets paged, an incident commander takes charge, responders are pulled in, customers are communicated with, and the team works the problem until service is restored. Mature programs define clear severity levels (a total outage is handled very differently from a minor degraded-performance issue) and clear roles, so that during a stressful outage nobody has to improvise who's in charge or what to do next. Good incident management leans heavily on preparation done beforehand: a well-maintained runbook for common failure modes, an on-call rotation with clear escalation paths, and observability tooling — dashboards, alerts, distributed tracing — that lets responders quickly narrow down what's actually broken instead of guessing. Tools like PagerDuty and Opsgenie are commonly used to route alerts to the right person and track the incident timeline automatically. After the incident is resolved, the process isn't done: a postmortem is written to capture the timeline, root cause, and follow-up actions, closing the loop so the same failure is less likely to recur. Organizations practicing site reliability engineering (SRE) treat this full lifecycle — detect, respond, resolve, learn — as a single continuous process rather than treating the postmortem as optional paperwork after the real work is done.
Key Concepts
- Defined severity levels that scale the response effort to the actual impact
- A named incident commander role to coordinate response and avoid conflicting actions
- Structured communication channels for both internal responders and external customers
- Integration with alerting and paging tools to route issues to the right on-call engineer
- A documented timeline captured in real time for later review
- A mandatory postmortem step that converts incidents into durable fixes
