Stop building in the dark. Build the smallest thing that tests your riskiest assumption, measure honestly, then decide: pivot or persevere.
About the book
Eric Ries's Build-Measure-Learn loop reframes a startup as a series of falsifiable experiments rather than a fixed plan to execute. The book's real contribution is innovation accounting — a way to measure progress with actionable metrics instead of vanity metrics that go up and to the right while telling you nothing — paired with a disciplined process for deciding when to pivot and when to persevere. It's aimed squarely at the moment before you overbuild: what's the minimum viable experiment that tells you the truth fastest and cheapest.
Best used for
—Scoping an MVP down to the smallest experiment that tests the riskiest assumption
—Replacing vanity metrics with actionable ones for a startup progress review
—Deciding whether to pivot or persevere on a product bet with real data
“I wasn't too surprised to find that Eric Ries is a great writer: clear, intellectually honest, articulate, and good-humored.”
— Stephanie Sun, Goodreads
