|---|---|---|---|---|
Purposedifferent | For a single, hard-to-explain deviation, the method exposes the causal chain behind the visible symptom. It keeps the cause open until a controllable condition emerges instead of a mere description. | For an existing solution under pressure to change, the method deliberately opens space for systematic variants. It directs attention to rebuilding, combining, and repurposing rather than only new basic ideas. This produces concrete evolution paths for products, offerings, or workflows. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. | When a central question feels too large, the method breaks it into neighboring topic fields with their own depth of ideation. It holds structure and openness at the same time, so adjacent perspectives don't get lost. This grows an idea space out of a core problem. |
