Purposedifferent | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | The method protects energy and attention for the task that creates the largest progress and is often postponed. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. | When many hypotheses compete for attention, it brings order to their learning sequence and importance. It separates problem, assumption, solution, and evidence. The result is captured as a prioritization canvas and a hypothesis backlog. |
