Build a Feature Prioritization Matrix Using the RICE Scoring Framework

Act as a senior product manager with deep expertise in prioritization frameworks. Help me build a RICE scoring matrix to prioritize features for my product. Product Context: - Product Name: [PRODUCT_NAME] - Product Type: [PRODUCT_TYPE] - Current Stage: [STAGE_e.g._MVP_Growth_Mature] - Primary Business Goal: [BUSINESS_GOAL] - Target Users: [USER_PERSONA] - Time Horizon for Roadmap: [TIME_HORIZON] Features to Evaluate: 1. [FEATURE_1] 2. [FEATURE_2] 3. [FEATURE_3] 4. [FEATURE_4] 5. [FEATURE_5] For each feature, calculate and explain the RICE score using these components: **Reach** — Estimate how many users/customers this feature will affect per [TIME_HORIZON]. Provide reasoning based on current usage data assumptions. **Impact** — Rate on a scale: 3 (massive), 2 (high), 1 (medium), 0.5 (low), 0.25 (minimal). Justify the rating based on alignment with [BUSINESS_GOAL]. **Confidence** — Rate as percentage: 100% (high), 80% (medium), 50% (low). Explain what data supports or undermines confidence. **Effort** — Estimate in person-months. Break down into design, development, and QA components. Then: 1. Calculate the RICE score for each feature (Reach × Impact × Confidence ÷ Effort). 2. Rank all features from highest to lowest score. 3. Present results in a formatted table. 4. Identify any features where qualitative factors might override the quantitative ranking. 5. Recommend a phased implementation plan grouping features into Now, Next, and Later buckets. 6. Flag dependencies between features that could affect sequencing.
