Core idea
A brief is not a specification dump
- A weak brief describes screens without decisions.
- A useful brief explains intent, scope, criteria, and tradeoffs.
- The brief should help a teammate ask better questions sooner.
Spec dump
Too much detail, no decision structure.
- All screens
- All edge cases
- No priority
Product brief
Enough context to review, prioritize, and build wisely.
- Problem
- Scope
- Criteria
- Risks
