Assumption Mapping

Surface hidden assumptions and prioritize which ones to validate before building.

When to Trigger

  • User is starting something new
  • User expresses uncertainty ("I think...", "probably...", "should work...")
  • User is about to invest significant effort
  • User mentions building without mentioning validation
  • User asks "what should I test first?"

Quick Start

Ask the user:

  1. "What are you building and for whom?"
  2. "What needs to be true for this to succeed?"
