Purposedifferent | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. | 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. | 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. |
