Objectives


  • Convert assumptions into testable hypotheses

  • Structure thinking for experimental validation

  • Identify critical assumptions that need testing

  • Plan systematic learning and validation

  • Reduce risk by testing before building

  • Enable evidence-based design decisions

  • Create framework for iterative learning

Outcomes


  • Hypotheses generated

  • Testable assumptions

  • Foundation for experimentation

Step-by-Step Instructions


  1. Identify key assumptions about:


  • User behaviors and needs

  • Solution effectiveness

  • Market conditions

  • Implementation feasibility


  1. Structure assumptions as testable hypotheses:


  • "We believe that [assumption]"

  • "Because [reasoning]"

  • "We will know this is true when [measurable outcome]"


  1. Prioritize hypotheses by:


  • Risk level if wrong

  • Confidence level

  • Cost to test


  1. Design experiments to test hypotheses

  2. Define success metrics and criteria

  3. Plan data collection methods

  4. Execute tests systematically

  5. Analyze results against hypotheses

  6. Update assumptions based on learning

  7. Generate new hypotheses as needed

Facilitator Tips


  • Make hypotheses specific and measurable

  • Focus on riskiest assumptions first

  • Design experiments that can prove hypotheses wrong

  • Keep test costs proportional to risk

  • Document all assumptions, not just obvious ones

  • Update hypotheses as you learn

  • Share learnings across team regularly

  • Use results to inform next design decisions
