Lean Customer Development by Al Álvarez

Build Products Your Customers Will Buy

A practical, hands-on guide to validating product ideas by systematically talking to customers and running small experiments before building, with concrete techniques for crafting hypotheses, recruiting and interviewing the right people, avoiding biased questions, and interpreting what customers actually need. It emphasizes rapid learning over premature features, provides scripts, templates and metrics for integrating customer discovery into iterative development, and shows how to reduce risk and align teams and stakeholders around evidence rather than opinion.
