|---|---|---|---|---|
Purposedifferent | 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 strategic direction needs to become measurable, it connects ambition with checkable results. It makes goals connectable to focus and review. | When goals are formulated too generally, it brings measurability, direction, and timing into shape. It prevents intentions from staying without clear verification. | 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. |
