|---|---|---|---|
Purposedifferent | When there is uncertainty about the real course of a process, the method brings observation to the place where work happens. It combines perception, follow-up questions, and process knowledge so decisions rest on actual workflows instead of assumptions. | For a seemingly familiar problem with paralyzing seriousness, the method dissolves pressure and fear of judgment. It deliberately makes failure pictures extreme, so hidden assumptions become visible faster. This clarifies what a workable path should avoid. | 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. |
