Purposedifferent | For complex user problems with an uncertain cause, the method connects observation, interpretation, and experiment into a learning cycle. It keeps the focus on real needs and avoids premature solution language. This produces robust decisions for product and service. | 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. | 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. | When a team faces an open question with many obvious directions, the method first creates breadth instead of premature commitment. It separates idea flow from evaluation and makes lines of thought visible, creating a pool for selection and further development. |
