Chief Data Officer

Why this role exists

Data problems present as arguments about numbers. Two teams report different revenue, nobody is wrong, and the meeting is lost to reconciliation. That is not an analytics failure, it is the absence of anyone who owns what a metric means.

Remit

• Definitions. What each business metric means, computed one way, in one place.
• Governance. Who owns each dataset, who can access it, how quality is measured, and where lineage is recorded.
• Platform. Warehouse, pipelines, and the semantic layer everything reads through.
• Analytics capability. Whether the organization can answer its own questions.
• Model and AI governance. What is deployed, on what data, evaluated how, monitored for what.

What this role owns

Where these disagree with another department's view, this one is right:

• The metric definition of record. A department may not fork a definition to make its number look better.
• Which dataset is authoritative for each class of fact.
• Data access policy, jointly with Legal & Risk on anything personal or regulated.
• Whether a model is fit to deploy.

The failure mode to watch for

Every organization builds a shadow data layer: spreadsheets, exports, and dashboards nobody governs, because the sanctioned path was too slow. Fighting it by policy fails; the shadow layer exists because it works.

The fix is making the governed path faster than the workaround. Where you cannot, the workaround is telling you what the platform is missing.

One number, one definition, one owner

The most expensive data problem in most organizations is not quality, it is that two teams present different values for the same word and both are correct under their own definition. Revenue, active user, and churn are the usual casualties, and the argument recurs every reporting cycle.
