|---|---|---|---|---|
Purposedifferent | 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. | When goals are formulated too generally, it brings measurability, direction, and timing into shape. It prevents intentions from staying without clear verification. | When the product question is unclear and time pressure is high, the method takes a team from an open idea to a testable solution. It connects problem understanding, decision, and learning in one compact format, lowering the risk of spending a lot of energy on a mere guess. | When strategic direction needs to become measurable, it connects ambition with checkable results. It makes goals connectable to focus and review. |
