|---|---|---|---|---|
Purposedifferent | When loud voices or hierarchy distort the idea search, the method creates a quiet entry into joint development. It gives everyone thinking space and gathers contributions without social brakes, making diversity more visible and easier to build on. | DIBB helps clarify target groups, value, goals, and priorities by making the logic behind a decision explicit. It captures results as a DIBB document, belief list, bet list, and learning report. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. |
