Data stewardship is the operational accountability for managing an organisation’s data assets across their lifecycle, ensuring they are accurate, well-documented, secure, and used in line with policy. Data stewards act as the human layer of data governance, owning definitions, resolving quality issues, and curating metadata and lineage. It bridges governance policy and day-to-day data practice, enabling trustworthy, reusable data.
Overview
- Stewards own business definitions, arbitrate data-quality issues, and maintain metadata, lineage, and access rules for the domains they cover.
- They sit between governance councils that set policy and the engineers and analysts who produce and consume data.
- Effective stewardship is what turns governance frameworks into reliable, reusable data in practice.
