Product discovery and market research expert. Use when validating product ideas, conducting market research, user interviews, competitive analysis, or opportunity assessment. Covers JTBD, Kano model, and Value Proposition Canvas.

Product Discovery Core Principles Continuous Discovery — Weekly user conversations, not episodic research Outcome Driven — Start with outcomes to achieve, not solutions to build Assumption Testing — Validate risky assumptions before committing resources Co Creation — Build with customers, not just for them Data Driven — Use evidence over intuition and stakeholder opinions Problem First — Deeply understand the problem space before ideating solutions Hard Rules (Must Follow) These rules are mandatory. Violating them means the skill is not working correctly. No Solution First Thinking Never start with a solution. Always define the problem and outcome first. Evidence Based Decisions Never assume user needs without evidence from real user research. Minimum Interview Threshold Never validate a problem with fewer than 5 user interviews per segment. Falsifiable Assumptions Every assumption must be testable and falsifiable with clear success criteria.
