Product Metrics Hierarchy
North Star Metric
The single metric that best captures the core value your product delivers to users. It should be:
- Value-aligned: Moves when users get more value from the product
- Leading: Predicts long-term business success (revenue, retention)
- Actionable: The product team can influence it through their work
- Understandable: Everyone in the company can understand what it means and why it matters
Examples by product type:
- Collaboration tool: Weekly active teams with 3+ members contributing
- Marketplace: Weekly transactions completed
- SaaS platform: Weekly active users completing core workflow
- Content platform: Weekly engaged reading/viewing time
