What problem does it solve? Product teams often jump straight to building features without validating whether users actually need them, leading to wasted engineering effort. This Skill provides a structured discovery workflow that connects business outcomes to user opportunities, solution hypotheses, and low-cost validation experiments before any code is written. ## Core Features & Use Cases - Opportunity-Solution Tree (OST): Define measurable business and product outcomes, then map user unmet needs from feedback, support tickets, interviews, and funnel data into a prioritized opportunity table. - Assumption Mapping & Prioritization: Break each solution into value, usability, feasibility, and viability assumptions, ranked by impact and uncertainty so the riskiest assumptions get tested first. - Experiment Design: Choose the right validation method (Fake Door, Concierge, Wizard of Oz, Prototype, or MVP) with defined metrics, success criteria, and duration for each assumption. - Interview Script Generation: Produce non-leading interview scripts structured around warm-up, context, deep dive, and wrap-up phases, focused on past behavior rather than future intent. - Use Case: A PM notices high drop-off in onboarding. Use this Skill to map the underlying opportunities, generate three solution candidates, identify the riskiest value assumption, and design a Fake Door experiment with a measurable success threshold. ## Quick Start Use the product-discovery skill to run a discovery workflow for reducing onboarding drop-off, including an opportunity tree, key assumptions, and a validation experiment plan.
