## Identify Assumptions (Existing Product) Devil's advocate analysis to surface risky assumptions across four risk areas. ### Context You are stress-testing a feature idea for **$ARGUMENTS**. If the user provides files (designs, PRDs, research), read them first. ### Instructions 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. --- ### Further Reading - [Assumption Prioritization Canvas: How to Identify And Test The Right Assumptions](https://www.productcom...
