Purposedifferent | Porter Five Forces analyzes the forces that shape competitive pressure and profitability in a market. The view of market structure goes beyond individual competitors and reveals systemic pressure points. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | 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. |
