What are Key Metrics?
Key Metrics are the few decisive figures that measure the actual progress of an organisation or product, so teams focus energy on what really matters instead of tracking many numbers at once.
DEFINITION
Key Metrics denote the most important measures of success for a product, campaign, or organisation. Ash Maurya established “Key Metrics” as a required field in the Lean Canvas: Which single figure shows whether the business model works? A North Star Metric is the decisive Key Metric that directly measures value creation for users. For Spotify, that was “Time Listening”, not the number of downloads. Key Metrics differ from vanity metrics: downloads, page views, and likes look good but say little about real value. Key Metrics, by contrast, are connected to business outcomes: retention, conversion, activation, or revenue. In OKR frameworks, Key Metrics correspond to Key Results: measurable outcomes that show progress towards an Objective.
CONNECTIONS
Agility
In agile teams, Key Metrics are the basis for data-driven decisions: Which features do we scale? What gets prioritised? Velocity and burndown charts are team metrics; Key Metrics refer to product success.
Leadership
Leaders decide which metrics really count. Those who track many figures lose focus. Key Metrics force a priority decision: What is truly important?
Artificial Intelligence
AI projects need clear Key Metrics from the start: accuracy, usage rate, or time saved. Without measurable Key Metrics, the benefit of AI implementations remains unclear and is hard to communicate.
KEY POINTS
- Key Metrics are the decisive few among many possible figures.
- Ash Maurya established Key Metrics as a required field in the Lean Canvas.
- The North Star Metric is the one Key Metric that directly measures value creation.
- Key Metrics differ from vanity metrics: they are connected to real value.
- In OKR frameworks, Key Metrics correspond to Key Results.
EXAMPLE
A B2B SaaS startup tracks ten different numbers: downloads, signups, logins, clicks, page views, likes, comments, shares, conversion rate, and MRR. After a Key Metrics workshop, they reduce to one North Star Metric: Weekly Active Users (WAU) who perform at least one core action. All other numbers flow into a dashboard as supporting metrics, but WAU drives product prioritisation.
MISCONCEPTIONS
Are more metrics better than fewer?
No. Many metrics create confusion and competing priorities. Key Metrics work with the principle of focus: one well-chosen Key Metric is more powerful than 20 vanity metrics.
Is the North Star Metric the same for every company?
No. It must measure the specific product’s value proposition. For a marketplace it might be transactions; for a SaaS tool, active users; for a course, completion rate.
