Purposedifferent | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | A Future Reality Tree shows how desired actions are meant to lead to a better system state. The method checks whether a path of change holds together logically before time flows into implementation. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | The method makes visible why two seemingly incompatible demands arise and which assumption must be tested to resolve the conflict. |
