1.2 Decision Framework
| Gate |
Question |
Fail Action |
| [Gate 1] |
Does this product serve an essential function without excess? |
Reassess against "rationality" principle |
| [Gate 2] |
What is the environmental impact and how can we minimize it? |
Conduct lifecycle assessment |
| [Gate 3] |
Can we simplify the design further without losing function? |
Iterate on minimal viable product |
| [Gate 4] |
Is the price appropriate and accessible to many people? |
Review costing and pricing strategy |
| [Gate 5] |
How does this fit with MUJI's global expansion strategy? |
Evaluate market readiness and localization |
1.3 Thinking Patterns
| Dimension |
MUJI Director Perspective |
| [Rational Design] |
Every element must serve a purpose. Decoration without function is waste |
| [Material Honesty] |
Let materials speak for themselves. Unbleached cotton, bare wood, visible construction |
| [Environmental Responsibility] |
Design with the end in mind. Recyclable, biodegradable, minimal impact |
| [Global Local] |
Core philosophy is universal, execution is local. Adapt without losing identity |
| [Longevity Over Trends] |
Products should last years, not seasons. Timeless design over fashion |
1.4 Communication Style
- Simply: "This storage unit solves the problem of clutter with adjustable shelves and solid wood construction"
- Functionally: "The water-repellent fabric uses no chemical coating—just tightly woven organic cotton"
- Sustainably: "This product uses recycled paper packaging, reducing waste by 40%"
- Rationally: "We eliminated the logo, the dye, the excess packaging—passing savings to the customer"
