Master Your Metrics

· 2 min · Quick read · Joost van der Laan

Metrics are only useful if they change what you do. Mastering your metrics means picking a small set of numbers that genuinely represent progress toward a goal, then building the habit of checking and acting on them — rather than collecting dashboards full of numbers that feel productive to watch but never change a decision.

The idea

Any system you manage — a project, a habit, a business — produces far more data than you can meaningfully act on. Vanity metrics (page views, follower counts, hours worked) feel good to report but rarely tell you what to do next. A mastered metric is one you can move with a specific action, and one whose movement tells you whether that action worked.

When to use it

How to apply it

  1. List every metric currently reported or tracked.
  2. For each, ask: “If this moved, would I change what I do?” Drop the ones where the answer is no.
  3. Keep the smallest set that still covers input (effort), process (execution), and outcome (result).
  4. Review the surviving metrics on a fixed cadence and write down the action each check produces.
