|---|---|---|---|
Purposedifferent | For a complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. | For complex problems with a fuzzy situation, the method cleanly separates search space and decision. It first creates breadth in understanding and then focus in elaboration. This brings open questions, problem definition, and solution path into a traceable movement. | 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. |
