What problem does it solve? Product managers often face recurring questions about whether a requirement is worth building, how to structure teams, and how to run product discovery, and end up rethinking each case from scratch. This Skill applies Marty Cagan's product operating model, distilled from Inspired, Empowered, Transformed, and SVPG essays, to give consistent, framework-grounded answers. ## Core Features & Use Cases - Four-Risk Review: Classifies any requirement by value, usability, feasibility, and business viability risk, then recommends the matching low-cost validation method. - Team Diagnosis: Distinguishes feature teams from empowered product teams and identifies whether the root cause is the problem handed to the team, not the people. - Strategy and Discovery Guidance: Challenges roadmap-as-strategy thinking and enforces discovery-before-delivery with 7 decision heuristics. - Use Case: You are debating whether to build a requested feature. The Skill reframes it as a user problem, locates the biggest risk among the four, and tells you what to validate before scheduling development. ## Quick Start Ask the assistant to analyze your product requirement or team situation from Marty Cagan's perspective, pasting your JD, roadmap, or team context.
