The revenue review starts, two dashboards go up, and the numbers disagree by four percent. For the next forty minutes, the leadership team debates whose extract is stale, whose filter is different, and whose definition of 'active customer' is correct. The decision the meeting existed to make is postponed. Again.
A trust problem, not a chart problem
Duelling dashboards are a symptom, and the disease is upstream. When metrics are computed in the reporting layer — in each tool, by each team, with each team's assumptions — divergence is guaranteed. No amount of dashboard polish fixes it, because the dashboards are faithfully displaying different answers to subtly different questions.
Definitions are the real asset
The durable fix is to move metric logic out of the tools and into a governed layer: each business metric defined once, computed once, owned by a named person, with its lineage traceable back to source systems. 'Active customer' becomes a definition with an owner and a change history — not a private formula in someone's workbook. The dashboards become thin views over shared answers.
Start with the five numbers that matter
This does not require a two-year data programme. Take the handful of metrics your executive meetings actually run on, reconcile them once, publish the definitions, and wire the dashboards to the shared layer. The meetings change character almost immediately: the argument moves from whose number is right to what to do about it — which is the argument you wanted.
