|---|---|---|---|
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 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. | 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. |
