7 connected components you can rename, recolor, and extend with AI.
An incident management process diagram maps how an operational incident is detected, handled, and closed. It includes automated detection and alerting, on-call paging, severity triage, mitigation and resolution, customer communication, and a post-incident review with action items. Branches separate minor incidents from major ones that require a war room and stakeholder updates.
SRE, DevOps, and IT operations teams use this template to align on response playbooks, define severity levels, and meet uptime commitments. It is essential when adopting an on-call rotation, integrating tools like PagerDuty, or running incidents against an ITIL or SRE framework so response stays fast and consistent.
Great for
- SRE runbooks
- On-call onboarding
- Incident response training
- Uptime planning
- Compliance documentation
Frequently asked questions
What is the incident management process?+
It is the lifecycle of detecting, responding to, resolving, and reviewing an operational incident. The diagram covers alerting, triage, mitigation, communication, and the postmortem.
What are the stages of incident management?+
Detection and alerting, on-call paging, severity triage, mitigation and resolution, stakeholder communication, and a post-incident review with follow-up actions.
How is incident severity decided?+
Severity is triaged by customer impact, scope, and urgency, which determines paging, war-room activation, and communication cadence. The diagram routes minor and major incidents differently.
Why run a postmortem?+
A blameless postmortem captures the timeline, root cause, and action items so the same failure is less likely to recur. It is the final stage of the process.
