# Plan Stage — Elaboration

## Criteria Guidance

### Good criteria — concrete and verifiable

- "Test strategy defines scope, approach, and resource requirements with explicit coverage targets for each quality dimension"
- "Risk-based prioritization ranks test areas by business impact and failure probability with justification"
- "Entry and exit criteria are defined for each test phase with measurable thresholds"

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

- "Strategy is defined"
- "Plan is ready"
- "Coverage is planned"
