Purposedifferent | When a navigation exists but search paths still fail, tree testing checks findability without visual distraction. The method shows whether labels, levels, and paths really lead to the intended destination. | 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 persistent errors or blockages, the method shifts the view to the opposite of the desired effect. It exposes the mechanics of failure and makes hidden causes easier to grasp. This makes improvement more concrete and the problem clearer. | When a search for ideas stalls, switching roles helps people step outside their own perspective and activate new logics of action. The method reduces habit because contributions arise from a different stance. This brings unfamiliar, often fitting solution approaches into play. |
