Feature Prioritization Framework

Quantitative scoring model to objectively prioritize features based on user value, business value, and ease of implementation.

Priority Scoring Formula

Priority Score = (User Value × 0.4) + (Business Value × 0.3) + (Ease of Build × 0.3)

Where:

  • User Value: 1-10 (impact on user experience)
  • Business Value: 1-10 (impact on retention/revenue)
  • Ease of Build: 10 = easy, 1 = hard (inverted effort)

Top 10 Features by Priority Score

Rank Feature User Value Business Value Ease Score Phase
1 Google Calendar Integration 9 10 7 8.7 1
2 Meeting Cost Calculation 10 10 6 8.8 1

Decision Rules

  • P0 (Must-Have): Score > 7.5 → Phase 1 MVP
  • P1 (Should-Have): Score 6.0-7.5 → Phase 2-3
  • P2 (Nice-to-Have): Score 4.0-6.0 → Phase 4+
  • P3 (Future/Backlog): Score < 4.0 → Don't build
