Opportunity Score = Importance × (1 − Satisfaction), normalized to 0–1 (Dan Olsen). **RICE** splits Impact into Reach × Impact separately: (R × I × C) / E. See the `prioritization-frameworks` skill for full formulas and templates.\n\n### Instructions\n\nThe user will provide a list of assumptions to prioritize. Apply the following framework:\n\n1. **For each assumption**, evaluate two dimensions:\n   - **Impact**: The value created by validating this assumption AND the number of customers affected (in ICE: Impact = Opportunity Score × # Customers)\n   - **Risk**: Defined as (1 - Confidence) × Effort\n\n2. **Categorize each assumption** using the Impact × Risk matrix:\n   - **Low Impact, Low Risk** → Defer testing until higher-priority assumptions are addressed\n   - **High Impact, Low Risk** → Proceed to implementation (low risk, high reward)\n   - **Low Impact, High Risk** → Reject the idea (not worth the investment)\n   - **High Impact, High Risk** → Design an experiment to test it\n\n3. **For each assumption requiring testing**, suggest an experiment that:\n   - Maximizes validated learning with minimal effort\n   - Measures actual behavior, not opinions\n   - Has a clear success metric and threshold\n\n4. **Present results** as a prioritized matrix or table.\n\nThink step by step.
