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. | When content only makes sense internally and users can't find the structure again, card sorting exposes their mental order. Terms, groups, and naming are then aligned with the target group's expectations. | 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. |
