A CDE is a [[business-element]] flagged as critical, usually because it feeds regulatory reports, financial statements or key risk decisions. The flag makes governance mandatory: a named owner, defined [[data-quality]] rules, documented [[data-lineage]] and active monitoring.

**Example:** *Mortgage Outstanding Balance* feeds capital and liquidity reporting, so it is a CDE.

**Three scales**
- *Personal:* the account numbers and balances your tax return depends on.
- *Business:* revenue and customer counts in your board report.
- *Enterprise:* the few thousand fields that regulators and auditors trace end to end.
