[Prompt] 90-day product experimentation plan

Business Prompt: Generate a 90-Day Product Experimentation Plan Based on Riskiest Assumptions

Prompt

Generate a structured 90-day product experimentation plan focused on the riskiest assumptions.

Include:

  • Plan Structure
  • Summary of the Product Idea
  • Table of Riskiest Assumptions:
    • Category
    • Assumption
    • Importance
    • Evidence Strength
  • Experiments by Purpose:
    • Discovery Experiments → explore user needs, pain points, behaviors
    • Validation Experiments → test adoption & engagement

For each experiment, specify:

  • Assumption being tested
  • Experiment Type (prototype test, A/B test, user interview, pre-sale, etc.)
  • Metrics & Measurements (CTR, engagement, retention, etc.)
  • Success Criteria (what validates/invalidates assumption)

Generate a timeline:
• Start with discovery experiments (light evidence)
• Follow with validation experiments (stronger evidence)

End with feedback:
“Does this experiment plan feel actionable? Would you add, remove, or refine anything?”


Use Case

For product managers, startup founders, and growth teams who want a practical 90-day roadmap to de-risk product ideas, prioritize riskiest unknowns, and validate assumptions with evidence-based experiments.
