|---|---|---|---|---|
Purposedifferent | When strategic direction needs to become measurable, it connects ambition with checkable results. It makes goals connectable to focus and review. | For a single, hard-to-explain deviation, the method exposes the causal chain behind the visible symptom. It keeps the cause open until a controllable condition emerges instead of a mere description. | 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 goals are formulated too generally, it brings measurability, direction, and timing into shape. It prevents intentions from staying without clear verification. |
