# Assumptions Mapping
## The What
Assumptions Mapping is used to find and check assumptions based on desirability, feasibility, and viability. It helps teams focus on testing high-risk assumptions, lowers uncertainty, and improves decision making.
## The How
Access the hypotheses: **Desirability**: Does the market want this idea? **Feasibility**: Can we deliver at scale? **Viability**: Is the idea profitable enough?
Map out **Evidence** vs **Importance**
Verify the top right quadrant where **critical assumptions** with little evidence are found
## :scroll: Tips

Not all hypotheses are equally important; some may not be critical to the business idea's success
