Assumption mapping
Assumption mapping plots each assumption on two axes — how important it is and how much evidence you have — to reveal which to test first. The high-importance, low-evidence assumptions (sometimes called leap-of-faith assumptions) are where the risk lives, so they earn the first, cheapest experiments.
