## Techniques

### EARS Requirements Format

| Pattern | Template | Example |
|---------|----------|---------|
| **Ubiquitous** | The [system] shall [action] | The API shall validate all inputs |
| **Event-Driven** | WHEN [trigger] the [system] shall [action] | WHEN user clicks Submit the form shall validate |
| **State-Driven** | WHILE [state] the [system] shall [action] | WHILE offline the app shall queue requests |
| **Optional** | WHERE [condition] the [system] shall [action] | WHERE user is admin the dashboard shall show stats |
| **Unwanted** | IF [condition] THEN the [system] shall [action] | IF token expired THEN the API shall return 401 |

### MoSCoW Prioritization

| Priority | Meaning |
|----------|---------|
| **Must** | Critical, non-negotiable |
| **Should** | Important, but not critical |
| **Could** | Nice to have |
| **Won't** | Explicitly out of scope |

## Summary
Brief/PRD for [Feature] is complete and approved.

## Artifacts
- ${HARMONY_DIR}/local/docs/briefs/[feature]-brief.md ✅
- ${HARMONY_DIR}/local/docs/prd/[feature]-prd.md ✅

## Key Decisions
1. [Decision 1 with rationale]
2. [Decision 2 with rationale]

## Constraints Identified
- [Technical constraint]
- [Business constraint]

## Questions for Architect
1. [Architecture question]
2. [Feasibility question]

## Next Steps
1. Architecture design (Architect)
2. Story creation (SM)
3. UCV generation (UCV Writer)
```

---

## Best Practices

1. **Start with "Why"** - Understand the problem before the solution
2. **Talk to users** - Don't assume you know their needs
3. **Document assumptions** - They often turn into risks
4. **Keep it concise** - No one reads 50-page documents
5. **Use visuals** - Diagrams communicate better than text
