🧭Data Steward Coverage Metrics

NEW

Also known as: Stewardship Coverage, Steward Assignment Coverage

Indicators that quantify how comprehensively data assets have assigned, accountable stewards across domains and criticality levels.

DESCRIPTION

Data steward coverage metrics assess whether each critical dataset, domain, or element has an accountable steward. Typical measures include percentage coverage, coverage by tier, backlog of unassigned assets, and SLA for assignment. They drive governance maturity, clarify decision rights, and support audit readiness. Integrations with catalogs, glossaries, and policy workflows update coverage automatically. Segmenting by domain reveals gaps and staffing needs. High coverage improves data quality outcomes by ensuring accountability.
