Most teams do not have a reporting problem. They have a data problem wearing a reporting costume.

When the same number lives in five systems, every team pulls its own version, and meetings turn into arguments about whose figure is right instead of what to do about it. No dashboard fixes that, because the dashboard is downstream of the mess.

The fix is upstream. We define, once, where each number is born and how it is calculated, then build reporting on top of that single definition. Everyone reads from the same place.

The dashboards that follow are almost boring to build. The hard and valuable work was agreeing on what the numbers mean before drawing a single chart.
