|---|---|---|---|
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. | 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. | For a search for solutions with many degrees of freedom, a grid emerges for systematic combinations. The method separates features, variants, and exclusion criteria, so the space gets explored deliberately. |
