What's in this template
8 connected components you can rename, recolor, and extend with AI.
An incident response decision tree branches an on-call engineer through the steps of handling a production incident. The root is alert detection, branching into severity triage, then into paths for declaring an incident, assigning a commander, mitigating the issue, and communicating to stakeholders, ending in resolution and a postmortem. Each branch represents a decision based on impact.
SRE teams, DevOps engineers, and incident commanders use it to standardize on-call behavior, reduce mean time to resolution, and train new responders. It anchors runbooks, on-call playbooks, and reliability training for teams adopting formal incident management.
Great for
- On-call playbooks
- Incident runbooks
- Reliability training
- SRE onboarding
- Process standardization
Make your own version with AI
Prefer to start from your own content? Describe it in one sentence and Infogiph generates a incident response decision tree you can edit and animate. For example:
“Incident Response Decision Tree showing Triage Severity, Declare Incident, Assign Incident Commander, Mitigate & Roll Back, Communicate to Stakeholders and Resolve & Verify”
Try it in the AI diagram generator, or read Decision tree examples, including incident severity.
How to customize this template
- Open it in the canvas with Use this template.
- Add environments and approval gates as their own nodes, such as Staging, Manual Approval and Production, so reviewers can see where a release can stop.
- Include the rollback path. A pipeline that only moves forward hides the step that matters most during an incident.
- Label cloud components with their region, availability zone and public or private subnet, since placement decides what fails together.
- Show where secrets come from, such as a secrets manager or sealed secrets, instead of leaving credentials implicit.
- Export a PNG or SVG for docs and slides, or a GIF or MP4 to keep the animation.
Frequently asked questions
What is an incident response decision tree?+
It is a branching flowchart that guides on-call engineers through detecting, triaging, mitigating, and resolving a production incident based on its severity.
What are the steps of incident response?+
The core steps are detection, severity triage, declaring an incident, mitigation, stakeholder communication, resolution, and a postmortem review.
How is incident severity decided?+
Severity is set by impact on users and revenue, with higher severities triggering an incident commander, broader paging, and formal communication.
Why run a postmortem after an incident?+
A blameless postmortem captures root cause and action items so the team can prevent recurrence and improve mean time to resolution.
