|---|---|---|---|---|
Purposedifferent | With unevenly distributed speaking time, the method brings every person into the contribution one after another. It prevents early voices from setting the direction while still producing a shared idea space. This makes participation plannable and the team's diversity visible. | With a stuck problem carrying many implicit assumptions, the method translates observations into open, workable questions. It sharpens the problem frame without pre-thinking the solution, turning frustration or fuzziness into a search space with clear direction. | When a central question feels too large, the method breaks it into neighboring topic fields with their own depth of ideation. It holds structure and openness at the same time, so adjacent perspectives don't get lost. This grows an idea space out of a core problem. | 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. |
