Purposedifferent | When a search for ideas stalls, switching roles helps people step outside their own perspective and activate new logics of action. The method reduces habit because contributions arise from a different stance. This brings unfamiliar, often fitting solution approaches into play. | When a problem has several possible contributing factors, the method sorts causes by cause areas. It prevents an initial hunch from blocking the view of other plausible drivers. | 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. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. |
