In this episode, he lays out a data-centric approach to systematically measure and improve AI, turning unreliable prototypes into robust, production-ready systems. Drawing from his experience getting countless teams unstuck, Hamel explains why the solution requires a "revenge of the data scientists." He details the essential mindset shifts, error analysis techniques, and practical steps needed to move beyond guesswork and build AI products you can actually trust. We talk through: The 10(+1) critical mistakes that cause teams to waste time on evals Why "hallucination scores" are a waste of time (and what to measure instead) The manual review process that finds major issues in hours, not weeks A step-by-step method for building LLM judges you can actually trust How to use domain experts without getting stuck in endless review committees Guest Bryan Bischof's "Failure as a Funnel" for debugging complex AI agents If you're tired of ambiguous "vibe checks" and want a clear process that delivers real improvement, this episode provides the definitive roadmap.
