Purposedifferent | 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. | For a problem with several suspected causes, the method builds a causal structure instead of a mere list. It makes visible how causes connect and where the strongest points of leverage lie. | 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. | 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. |
