Purposedifferent
The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success.The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.In dynamic situations, decisions become outdated faster than they can be prepared. The OODA Loop holds observing, orienting, deciding, and acting together as a recurring rhythm so reaction does not slide into inertia.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.
