## Concept Usage by WDS Phase

### Phases 1-7: New Product Development

**Approach:** Greenfield + Kaikaku

**Characteristics:**

- Starting from scratch
- Complete user flows
- Revolutionary change
- Full Design Deliveries (DD-XXX)
- Months of work

**Concepts:**

- Greenfield Development
- Kaikaku (改革) - Revolutionary Change

---

### Phase 8: Ongoing Development

**Approach:** Brownfield + Kaizen

**Characteristics:**

- Existing product
- Incremental improvements
- Continuous improvement
- System Updates (SU-XXX)
- 1-2 week cycles

**Concepts:**

- Brownfield Development
- Kaizen (改善) - Continuous Improvement
- Muda (無駄) - Waste elimination

---

## Quick Reference

### When Starting a Project

**Question:** "Are you building from scratch or improving existing?"

**Answer 1: From Scratch**
→ Greenfield + Kaikaku
→ Phases 1-7
→ Design Deliveries (DD-XXX)
→ Revolutionary change

**Answer 2: Existing Product**
→ Brownfield + Kaizen
→ Phase 8
→ System Updates (SU-XXX)
→ Continuous improvement

---

### When in Phase 8

**Question:** "Should I do small improvements or big redesign?"

**Small Improvements (Kaizen 改善):**

- ✅ Product is working
- ✅ Want low-risk changes
- ✅ 1-2 week cycles
- ✅ Continuous learning
  → Stay in Phase 8, create System Updates

**Big Redesign (Kaikaku 改革):**

- ✅ Product needs overhaul
- ✅ Fundamental problems
- ✅ Months of work
- ✅ Revolutionary change
  → Return to Phases 1-7, create Design Deliveries

## Key Takeaways

**For Designers:**

1. Understand if you're in Greenfield or Brownfield context
2. Choose Kaikaku (revolutionary) or Kaizen (continuous) approach
3. Use appropriate deliverables (DD-XXX vs SU-XXX)
4. Follow appropriate workflow (Phases 1-7 vs Phase 8)

**For Documentation:**

1. Glossary is the source of truth
2. Concepts are integrated where relevant
3. Quick references in workflow steps
4. Consistent terminology throughout

**Philosophy:**

- Kaikaku to establish, Kaizen to improve
- Greenfield gives freedom, Brownfield gives context
- Small improvements compound over time
- Revolutionary change when necessary, continuous improvement always
