# Triage Stage — Elaboration

## Criteria Guidance

### Good criteria — concrete and verifiable

- "Incident brief includes severity level (SEV1-4) with justification based on user impact"
- "Blast radius assessment identifies all affected services, regions, and customer segments"
- "Communication plan specifies who has been notified and through which channels"

### Bad criteria — vague (no clear check)

- "Severity is assessed"
- "People are notified"
- "Incident is triaged"
