identify-assumptions-existing Identify risky assumptions for a feature idea in an existing product across Value, Usability, Viability, and Feasibility. Uses multi-perspective devil's advocate thinking. Use when stress-testing a feature idea, doing risk assessment, or preparing for assumption mapping. Triggers: identify assumptions, risk assessment, devil's advocate, assumption mapping, feature risks, what could go wrong.

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.
