This one's for product managers and founders who need to validate ideas before burning engineering time. It enforces hard rules like no solution-first thinking, minimum five user interviews per segment, and evidence-based decisions with clear success metrics. You get frameworks like JTBD, Kano Model, and Value Proposition Canvas, plus Marty Cagan's 10-question opportunity assessment. The weekly continuous discovery structure is solid: customer interviews, assumption testing, and opportunity mapping. Honestly, the strictness around falsifiable assumptions and killing HiPPO-driven features is refreshing. If you're tired of building things nobody wants, this will force the discipline to talk to users first.
