|---|---|---|---|
Purposedifferent | When an environment of users, systems, and constraints is hard to grasp, it puts the context compactly on the table. It creates a clear reading of influence, boundary, and dependency. | 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. | With new ideas or requests, the conversation often turns to solutions too early and to effect too little. An Impact Filter forces the initiative into an effect perspective and checks whether it creates a relevant difference. |
