Purposedifferent | For a seemingly familiar problem with paralyzing seriousness, the method dissolves pressure and fear of judgment. It deliberately makes failure pictures extreme, so hidden assumptions become visible faster. This clarifies what a workable path should avoid. | For a complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. | 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. |
