|---|---|---|---|
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 topic is still unclear and too many thoughts surface at once, Mind Mapping creates an open surface for ordering them. It makes connections, subtopics, and starting points visible without fixing them too early. | For persistent errors or blockages, the method shifts the view to the opposite of the desired effect. It exposes the mechanics of failure and makes hidden causes easier to grasp. This makes improvement more concrete and the problem clearer. |
