Purposedifferent | In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected. | 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. | 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. | In a tightly timed design process with many participants, the method pools several lines of thinking in a short time. It brings parallel design energy without letting the discussion tip into endless coordination. This quickly produces solid directions for architecture or space. |
