North Star Metric
A North Star Metric is the single key metric capturing core customer value and predicting long-term business growth.
“If you measure the wrong thing, you will get the wrong behaviors and build the wrong company.”
Without a clear North Star Metric, different functional departments optimize for conflicting vanity metrics (marketing optimizes for page views, sales for bookings, engineering for velocity). A unified North Star Metric aligns the entire company around customer value creation.

Richard Ewing’s Research Thesis
The North Star Metric must measure customer value realization, not company vanity.
Why This Specification Exists
Different teams pull in opposite directions by optimizing for conflicting departmental metrics.
Tracking dozens of disconnected KPIs on executive dashboards.
No single cohesive metric linking customer value creation to enterprise business growth.
The North Star Metric establishing unified alignment across product, engineering, and business teams.
What Changes If You Believe This?
Engineering prioritizes infrastructure investments that directly improve the North Star input metrics.
Connects leading product usage metrics to forward-looking revenue forecasts.
Product squads have unambiguous clarity on which user behaviors to encourage and measure.
Establishes guardrail metrics to ensure rapid growth does not compromise data integrity or compliance.
Recommended Action by Role

Frequently Asked Questions
Q:What is a North Star Metric?
A single high-level metric that reflects the core value delivered to customers and predicts long-term company health.
Q:How do you choose a North Star Metric?
Identify the moment the customer achieves the primary benefit of the product (e.g., Spotify: Time Spent Listening; Airbnb: Nights Booked; Slack: Messages Sent in Teams).
