Surface hidden assumptions. Prioritize validation efforts. Reduce project risk. Create a learning agenda focused on critical unknowns.
Completed assumption grid. Mapped assumptions by risk and certainty. Prioritized validation plan.
New assumptions will emerge during mapping—capture them. Use this early in projects to avoid building on shaky ground. I've seen teams get bogged down arguing about the placement of an assumption. Don't let that happen. Focus on the high-risk, uncertain quadrant first.
