## Lessons
### [Lesson 1: The Chaos Problem](lesson-01-chaos-problem.md)
**Time:** 6-8 minutes
Why projects fail before they start:
- The cost of no foundation (wasted design, misalignment, scope creep)
- What the Product Brief does (single source of truth)
- Time investment vs payoff (30-45 min saves weeks)
- 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:
- **What & Why** - Vision and positioning
- **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
What a Product Brief actually looks like:
- Template structure walkthrough
- Key sections and what goes in each
- How to keep it concise (2-3 pages max)

- Built-in best practices (SMART goals, constraint checklists)
- Two levels: Simplified vs Complete (based on project needs)
### [Lesson 5: Using Your Product Brief](lesson-05-using-brief.md)
**Time:** 6-8 minutes
How this document powers your entire project:
- How designers use it (reference for every decision)
- How developers use it (understand the "why")
- How stakeholders use it (track progress, prevent scope creep)
- How product managers use it (roadmaps, user stories)
- When to update it (and when not to)
### [Lesson 6: Additional Strategic Documents](lesson-06-additional-documents.md)
**Time:** 8-10 minutes
Expanding your strategic foundation:
- Core Features Document (feature prioritization)
- Tone of Voice Guide (brand personality, communication)
- Visual Design Brief (visual direction, inspiration)
- Technical Architecture Brief (platform, integrations)
- Content Strategy (content types, publishing)
- Localization Strategy (multi-language planning)
- Accessibility Requirements (compliance, user needs)

## Tutorial
**[Tutorial: Create Your Product Brief →](tutorial-04.md)**
Step-by-step hands-on guide to creating your Product Brief with Saga.
**Time:** 30-45 minutes
**What you'll create:** Complete Product Brief document

## Key Concepts
**Product Brief:**
- 2-3 page strategic document
- Answers 5 critical questions (What/Why, Who, How We'll Know, Context, Boundaries)
- Single source of truth for entire team
- Created in 30-45 minutes through AI-guided conversation

**The 5 Strategic Questions:**
1. **What & Why** - Vision and positioning (what you're building, why it matters, who it's for)
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 (SMART goals, checklists)
- **Flexible:** Two levels (simplified vs complete)
- **Living:** Easy to update as you learn
**Additional Documents:**
- Optional strategic documents created as needed
- All live in Project Brief folder
- Same conversational approach with Saga
- Expand foundation based on project complexity
