Most dashboards are collections. Someone decided to put every relevant number on one page. The result is a data landfill — a screen that answers the question "how are we doing?" with a 360-degree view of nothing in particular.

A good dashboard answers a specific question for a specific person in under 30 seconds. Everything else is noise.

The 30-Second Test

Ask someone to look at your dashboard for 30 seconds. Then ask them:

  • What's the most important number on this screen?
  • Is it on track or off track?
  • If it's off track, do you know what to do next?

If they can't answer all three, the dashboard is failing. Not because it lacks data — because it lacks priority. The most important information should be the most visible. Everything else should be one click deeper.

The Four Dashboard Types

  1. Scorecard — a snapshot of key numbers, usually with status indicators. Best for: weekly team updates. Worst for: operational decisions.
  2. Trend dashboard — shows how metrics change over time. Best for: understanding direction and velocity. Worst for: pinpointing cause.
  3. Exception dashboard — highlights only what's off track. Best for: operator dashboards and daily standups. Worst for: strategic overview.
  4. Exploration dashboard — allows free-form filtering and drill-down. Best for: investigating a known problem. Worst for: passive monitoring.

Most organizations need all four, for different audiences and different questions. Building one dashboard and hoping it serves all four is how you end up with a data landfill.

Add one maintenance rule: every dashboard gets an owner and an expiry date. If no one owns the definition, freshness, and cleanup, the dashboard becomes archaeological evidence of decisions nobody makes anymore.
