|---|---|---|---|---|
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. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. | 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 an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. |
