assumption-mapper Extract and risk-rate hidden assumptions in a product brief or PRD. Use when asked to review a product brief for assumptions, audit a PRD for risks, find hidden assumptions, validate product plans, or run an assumption analysis. Produces a prioritised assumption map with confidence and impact scores, recommended validation methods, and critical assumption flags.

Assumption Mapper Skill

Surface and prioritize the untested assumptions embedded in any product plan before development begins.

Required Inputs

Ask the user for these if not provided:

  • Product brief, PRD, or concept description (even rough notes work)
  • Stage (concept / discovery / pre-build / post-launch — affects which assumptions matter most)

Process

  1. Read the provided brief, PRD, or concept description
  2. Extract assumptions across four categories:
    • Desirability (do users want this?)
    • Feasibility (can we build it?)
    • Viability (will it sustain the business?)
    • Usability (can users actually use it?)
  3. Score each assumption:
    • Confidence (1-5): How sure are we this is true?
    • Impact (1-5): How badly does the plan fail if this assumption is wrong?
    • Priority = Impact Confidence (higher = test first)
  4. Validate completeness — Ensure at least one assumption per category. If a category is empty, re-read the brief looking specifically for that type.
  5. Output a ranked list with recommended validation methods

Output Structure

Assumption Map: [Feature/Product Name]

Assumption Category Confidence Impact Priority Validation Method
[assumption] [type] [1-5] [1-5] [score] [method]

Critical Assumptions (Impact 4+ and Confidence 2 or below)

[Flagged items with detailed validation recommendations]

Top 3 Assumptions to Validate First

[Detailed recommendations including specific research method, estimated effort, and what the result would change]

Example (Partial)

Input: "We're building a self-serve onboarding flow to reduce time-to-value for SMB customers."

Assumption Category Confidence Impact Priority Validation Method
SMB users can complete onboarding without human help Usability 2 5 3 Unmoderated usability test (n=8)
Faster onboarding correlates with higher retention Viability 3 4 1 Cohort analysis of current onboarding times vs. 90-day retention
The current onboarding is the primary reason for slow time-to-value Desirability 2 4 2 User interviews with recent churned SMB accounts

Quality Checks

  • At least one assumption per category (Desirability, Feasibility, Viability, Usability)
  • All Impact 4+ / Confidence 2 assumptions flagged as CRITICAL
  • Each validation method is specific (not just "do research" — name the method and sample size)
  • Priority scores are consistent (Impact Confidence, higher = more urgent)
