Decision Making
Assumption Surfacing
Purposedifferent
For strategic decisions with high reach, agreement and gut feeling are often not enough. Red teaming brings deliberate opposition into the situation and tests where a plan breaks under real counterarguments.The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible.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.
