To validate a business idea before building, you design structured experiments such as fake doors, concierge, or presales to test desirability, feasibility, and viability. You write testable hypotheses and use Test Cards to capture evidence-driven decisions.

A structured testable hypothesis for product discovery follows the format: We believe [customer segment] will [action] because [reason]. This direct framing ensures experiments target specific customer behaviors to validate assumptions.

Assumptions Maps prioritize product validation experiments by identifying and ranking your riskiest bets. This structured mapping focuses testing efforts on critical desirability, feasibility, and viability assumptions before development.

Lean startup experiments to test customer demand include fake doors, Wizard of Oz, presales, and Letters of Intent. These discovery and validation techniques measure real customer behavior without fully building the product.

Use Learning Cards in the idea validation process immediately after running an experiment. They capture experimental results, document evidence-driven decisions, and outline next steps for the product discovery workflow.
