|---|---|---|---|---|
Purposedifferent | When a usage scenario needs to become understandable early, it condenses situations, context, and flow into a legible sequence. It helps check concept ideas before anything gets built. | 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 the picture of the problem still needs to become solid, it asks about real situations and consequences. It separates genuine suffering from mere interest in a solution. | When a solution idea is already on the table, it checks how it is understood and evaluated. It looks for resonance, objections, and missing fit early in the conversation. |
