It directs attention to the course of events, conditions, and effective countermeasures. | Helps clarify ideas, open questions, and testable next steps in concrete terms. It opens the thinking space, collects ideas, and leads to testable options. The result is captured as a star-shaped question map, question list, and assumption list. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
