Purposedifferent | For a search for solutions with many degrees of freedom, a grid emerges for systematic combinations. The method separates features, variants, and exclusion criteria, so the space gets explored deliberately. | Plans often contain assumptions that were never openly stated and remain dangerous precisely because of that. Assumption Surfacing makes these silent premises visible and prioritizes which of them carry the initiative or could sink it. | 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. | For persistent errors or blockages, the method shifts the view to the opposite of the desired effect. It exposes the mechanics of failure and makes hidden causes easier to grasp. This makes improvement more concrete and the problem clearer. |
