Decision tree (30 seconds)

  1. Paying customers blocked on a core workflow? → Critical
  2. Core feature degraded for many? → High
  3. Limited impact or workaround? → Medium
  4. Otherwise → Low

Incido setup

  • Create matching severity levels in org settings
  • Link Critical/High to escalation policies
  • Train support to use the same definitions

How to use this template

  • Review with support and product. Severity should match customer experience.
  • Wire levels into escalation routing (Critical ≠ Medium paging).
  • Revisit after major incidents.

Incido severity levels drive colors, notification urgency, and escalation routing. Keep definitions aligned with your policies.

FAQ

Frequently Asked Questions

How to use and adapt this template.

How many levels?

Four is the sweet spot. More than five usually adds confusion, not clarity.

Who sets severity?

First responder or commander sets initial severity; adjust as impact becomes clear.

Severity vs status page?

Customer-visible impact drives public messaging. Internal Low incidents rarely need a status post.
