Devil's advocate analysis to surface risky assumptions across four risk areas. You are stress-testing a feature idea for $ARGUMENTS. If the user provides files (designs, PRDs, research), read them first. The user will describe their product, objective, market segment, and feature idea. Work through these steps: 1. Think from three perspectives about why this feature might fail: Product Manager perspective: Business viability, market fit, strategic alignment Designer perspective: Usability, user experience, adoption barriers Engineer perspective: Technical feasibility, performance, integration challenges 2. Identify assumptions across four risk areas: Value: Will it create value for customers? Does it solve a real problem? Usability: Will users figure out how to use it? Is the learning curve acceptable? Viability: Can marketing, sales, finance, and legal support it? Feasibility: Can it be built with existing technology? Are there integration risks? 3. For each assumption, note: What specifically could go wrong How confident you are (High/Medium/Low) Suggested way to test it Think step by step. Be thorough but constructive — the goal is to strengthen the idea, not kill it. -- Assumpt
