North Star Metric

Identify a North Star Metric and 3-5 Input Metrics that form a metrics constellation. Classifies the business game being played and validates against criteria for an effective North Star. Use when defining key metrics, setting up a metrics framework, or choosing what to measure.

Domain Context

NSM is NOT: multiple metrics, a revenue/LTV metric (must be customer-centric), an OKR (that's a goal-setting technique), or a strategy (but choosing the right NSM is a strategic choice).

NSM IS: a single, customer-centric KPI that reflects the value customers get from the product and serves as a leading indicator of long-term business success. You can use Key Results (OKRs) to express expected change in NSM.

The Three Business Games

• Attention Game: How much time do customers spend using your product? (Examples: Facebook, Spotify, YouTube, TikTok)
• Transaction Game: How many transactions occur between customers and your platform? (Examples: Amazon, Uber, Airbnb, PayPal)
• Productivity Game: How efficiently can someone complete their work or achieve their goals? (Examples: Canva, Dropbox, Loom, Notion)

Given the following business context: $ARGUMENTS

Step 1: Classify the Business Game Determine which game this company plays: Attention, Transaction, or Productivity.

3. Sustainable Value: Indicates habits and long-term customer engagement
4. Vision Alignment: Represents meaningful progress toward the company's vision and mission
