|---|---|---|---|---|
Purposedifferent | When a decision needs to be prepared quickly, the method generates many solution-close variants in a short time. It deliberately relies on pace to undercut self-censorship and perfectionism. This quickly produces a usable field for prioritization and further work. | With only a few minutes available and a still-fuzzy solution search, the method forces a wide range of variants. It produces fast sketches before the first idea can settle in, making different directions directly comparable and open to 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. | 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. |
