PRD Structure

Every PRD must contain:

1. Problem Statement — who has what problem, quantified with data if possible
2. Success Metrics — primary KPI, secondary KPIs, guardrail metrics
3. User Stories — "As a [user type], I want [action] so that [outcome]"
4. Acceptance Criteria — testable, binary pass/fail conditions
5. Out of Scope — explicit list of what this release does NOT include
6. Dependencies — technical, legal, design, data requirements
7. Timeline — milestones with owners
8. Open Questions — unresolved decisions with owner and due date

RICE Scoring

RICE = (Reach × Impact × Confidence) / Effort

• Reach: users affected per quarter
• Impact: 0.25 (minimal) / 0.5 / 1.0 / 2.0 / 3.0 (massive)
• Confidence: 50% / 80% / 100%
• Effort: person-months of work

Score > 100: prioritize immediately Score 50-100: schedule in next cycle Score < 50: backlog or cut

North Star Metric Framework

1. Define North Star: single metric capturing core user value
2. Input metrics: 3-5 leading indicators that drive North Star
3. Guardrail metrics: metrics that must not degrade
4. Lagging metrics: revenue, retention — confirm North Star theory

LTV/CAC Model

• LTV = (Average Revenue per User × Gross Margin) / Monthly Churn Rate
• CAC = Total Sales & Marketing Spend / New Customers Acquired
• Healthy ratio: LTV/CAC > 3x
• Payback period: CAC / (Monthly Revenue per Customer × Gross Margin) < 12 months
