North Star Metric
A single metric that represents the business's true growth and the value it delivers to customers. Amazon: number of Prime products available. Shopify: partner GMV. A store: customers who bought more than twice.
In practice
A North Star Metric creates organizational focus. When everyone works to improve one metric, drivers are clear and priorities align. Marketing, product, service — all contribute to the North Star. It's the 'why' behind every other KPI.
Common misconception
'Revenue is the North Star.' Revenue is an outcome, not a value delivered. Revenue can grow even if customers aren't happy (you sold a lot to people who'll return it). A good North Star = customer value + growth. Example: 'customers who purchased 3+ times.'
How to fix it
North Star unclear? (1) Ask: 'which customers best demonstrate our success?' (2) Ask: 'what action, if a customer took it, would tell us we're serving them well?' (3) Check: does improving the North Star lead to improved revenue? (4) Keep it simple — a metric every employee understands.
Example
Bookstore: tried revenue as its North Star. Worked to boost sales ← big discounts ← revenue rose, margin fell, LTV fell. Switched to 'customers who bought a second book within 60 days.' Focus: product quality + onboarding + recommendations. Revenue rose 28% within a year — a healthier outcome.
Priority
Define a North Star metric before setting OKRs. A 2-hour workshop with the full management team. Questions: what action signals real value? What's measurable? What drives LTV? Outcome: one clear metric with an owner.
