Describe the business idea you want to test. Find the assumptions you need to prove and get a series of affordable experiments to run first.

Stress-testing your assumptions…
Extracting assumptions, scoring risk and evidence gaps, and sequencing your experiments.
2 — The Idea, Sharpened
3 — Assumption Map
Every idea is a stack of beliefs. Here they are, sorted by the three risks that sink most ventures. Each carries a Risk score (how fatal if it's wrong) and an Evidence Gap (how little you actually know) — multiplied into a priority out of 25.
4 — What to Test First
Ranked by risk × evidence gap. The assumptions at the top are the ones most likely to be wrong and most likely to kill the idea — your kill-shots. Start there.
5 — Your Testing Plan
An ordered sequence drawn from the 44 experiments in Testing Business Ideas — cheapest, fastest evidence first, escalating only as each assumption survives. For each one: how it works, how to run it for this idea, what it costs, and the signal that means "keep going."

The full library your plan draws from, from free interviews to pre-sales.
