|---|---|---|---|---|
Purposedifferent | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | 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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | When a team faces an open question with many obvious directions, the method first creates breadth instead of premature commitment. It separates idea flow from evaluation and makes lines of thought visible, creating a pool for selection and further development. |
