|---|---|---|---|
Purposedifferent | When a usage scenario needs to become understandable early, it condenses situations, context, and flow into a legible sequence. It helps check concept ideas before anything gets built. | IBIS structures thinking about complex questions as a sequence of issues, ideas, and arguments. The method keeps discussions open without forcing them into premature consensus. | 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. |
