Assumption Mapper

What it does

• Reads a product brief, PRD, or rough concept notes and pulls out the untested assumptions.
• Sorts them across four lenses — Desirability, Technical feasibility, Business viability, Usability — requiring at least one per lens so blind spots surface.
• Scores each assumption for load-bearing (1–5) and confidence (1–5), ranks by Priority = load-bearing − confidence, and tags provenance as [data] or [intuition].
• Mechanically flags anything at Impact 4+ / Confidence ≤2 as CRITICAL.
• Picks the single riskiest assumption and names the cheapest test runnable this week, plus what failure would look like.
• Outputs a ranked assumption table and a "Top 3 to validate first" list, then hands the unresolved bet off as an Open Question for the PRD stage.
• Ships with a 0–40 scoring rubric, quality checks, and anti-patterns (e.g. never defaulting to "user interviews" for everything).

Who it's for

• PMs and product owners who want a risk pass before writing a PRD or starting build.
• Teams that inflate confidence simply because nobody challenged an assumption.
• Founders and leads reviewing incoming feature proposals.
• Note: it's product-management specific, needs an input document, and this copy is a machine translation into Spanish.

Example uses

1. Audit a self-serve onboarding brief — from "reduce time-to-value for SMB customers," it produces rows like "SMB users can complete onboarding without human help" (Usability, confidence 2 / impact 5 → CRITICAL) with an unmoderated usability test (n=8) as the validation method.
2. Risk-audit an existing PRD — paste the PRD and ask for a risk audit; it fills in the neglected technical and commercial assumptions and returns a Top 3 with effort estimates.
3. Design a validation plan — for the riskiest bet it recommends concrete methods (cohort analysis, fake door, desk check, engineering spike) with sample size and effort instead of generic "do research."
