|---|---|---|---|
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 loud voices or hierarchy distort the idea search, the method creates a quiet entry into joint development. It gives everyone thinking space and gathers contributions without social brakes, making diversity more visible and easier to build on. | 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. |
