|---|---|---|---|
Purposedifferent | For a critical top event with several possible triggers, the method logically models failure paths. It makes visible which combinations of conditions can lead to damage. | When a group without a fixed agenda needs to get into useful conversations quickly, Lean Coffee structures the start around interests rather than a presentation. The group itself negotiates which topics get time first and which wait. | When three perspectives matter at the same time, a Three-Circle Venn Diagram shows the overlaps and remainders precisely. It makes visible where shared effect arises and where only a partial perspective applies. |
