Purposedifferent | 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. | Helps clarify ideas, open questions, and testable next steps in concrete terms. It opens the thinking space, collects ideas, and leads to testable options. The result is captured as a star-shaped question map, question list, and assumption list. | 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 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. |
