Assumption Mapping Skill

Purpose

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

Process

Read the provided brief, PRD, or concept description

Extract all 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?)

For each assumption, score:

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 minus Confidence (higher score = test this first)

Output a ranked list with recommended validation methods

Output Format

Assumption Map: [Feature/Product Name]
