The Metrics That Actually Matter

Give a team a metric and they will move it — which is exactly the problem. Choose the wrong number and you get a great deal of energy spent making a chart look good while the thing you actually care about goes nowhere. The art of good measurement is not collecting more; it is choosing the few numbers that, when they improve, mean the business genuinely got better.

Vanity versus value

A vanity metric is one that reliably goes up and rarely tells you what to do. Total registered users, page views, hours logged, features shipped — impressive on a slide, useless as a decision. A value metric moves with the health of the business and points to a clear action when it moves. The distinction is not about the number itself but about whether it changes what you do.

• Vanity: cumulative sign-ups, total downloads, gross activity.
• Value: active usage, retention, conversion, unit economics, cycle time.

A simple test for any metric

Before a number earns a place on the dashboard, run it through three questions. A good metric is actionable, so a change in it points to a decision. It is comparable, so you can tell good from bad over time. And it is honest, meaning it is hard to move without actually improving the underlying thing.

• Actionable — does moving it imply a specific decision?
• Comparable — can you judge whether it's good, over time or against a benchmark?
• Honest — is it hard to game without real improvement?

Building a metric that drives behaviour

Once you have the right few, protect them. Pair every headline number with a guardrail so no one improves it by breaking something else — grow revenue without wrecking margin, speed up delivery without collapsing quality. And keep the set small. A team that owns three numbers it understands will out-perform one drowning in thirty it doesn't.

Measurement is leverage: it quietly tells your organisation what to care about. Point that leverage at the handful of numbers that reflect real value, guard them against gaming, and you will spend far less energy admiring charts — and far more moving the business.
