- Your insurance policy against chaos

### [Lesson 2: The 5 Strategic Questions](lesson-02-five-questions.md)

**Time:** 10-12 minutes

What every Product Brief must answer:

- **Who** - Target users and stakeholders
- **How We'll Know** - Success criteria (measurable outcomes)
- **Context** - Competitive landscape (alternatives, differentiation)
- **Boundaries** - Constraints (technical, business, design)

### [Lesson 3: The Document Structure](lesson-03-document-structure.md)

**Time:** 8-10 minutes

2. **Who** - Target users and stakeholders (who uses it, who decides, who builds)
3. **How We'll Know** - Success criteria (user, business, technical, design metrics)
4. **Context** - Competitive landscape (alternatives, differentiation, positioning)
5. **Boundaries** - Constraints (technical, business, design limitations)

**WDS Advantage:**
- **Speed:** 30-45 min vs days of meetings
- **AI-Guided:** Saga asks the right questions, no blank page
- **Conversational:** Natural dialogue, not form-filling
- **Professional:** Built-in best practices (the SMART model, checklists)

**Additional Documents:**
- Optional strategic documents created as needed
- All live in Product Brief folder
- Same conversational approach with Saga
