Purposedifferent | When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. | 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 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. | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. |
