DIBB
Purposedifferent
The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success.When knowledge is distributed and direct dominance should be avoided, groups quickly fall under the sway of their opinion leaders. The Delphi Method gathers assessments iteratively and gradually brings expert judgments closer together.The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.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.
