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
- Scorecard — a snapshot of key numbers, usually with status indicators. Best for: weekly team updates. Worst for: operational decisions.
- Trend dashboard — shows how metrics change over time. Best for: understanding direction and velocity. Worst for: pinpointing cause.
- Exception dashboard — highlights only what's off track. Best for: operator dashboards and daily standups. Worst for: strategic overview.
- 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.
