Definition
A Data Steward is responsible for the day-to-day care, quality, definition, and proper use of data within a governed domain.
While the Data Owner is accountable and has decision authority, the steward helps make governance operational.
Simple Mental Model
Owner = accountable. Steward = keeps it working properly day to day.
How It Works
A Data Steward may:
- Review quality issues
- Maintain definitions
- Validate classifications
- Coordinate corrections
- Update metadata
- Resolve routine questions
- Escalate policy decisions to the Data Owner
Example
If the organization defines Roku, Apple TV, Android TV, and Fire TV as Connected TV, the owner approves that standard.
The steward helps detect inconsistent classifications and ensures future records follow the standard.

My Company / Real-World Context
You may not need formal "Data Steward" job titles. Stewardship can be assigned to existing roles such as analysts or operations staff.
The key is that someone is clearly responsible for routine health and consistency.
CTO Perspective
Governance structures can look great on PowerPoint while nobody actually performs the work.
Ask:
Who notices when this data becomes wrong, and what are they expected to do?
Questions to Ask
- Who performs day-to-day stewardship?
- What quality issues do they monitor?
- What can they decide themselves?
- What must be escalated to the Data Owner?
- Is stewardship part of their real workload?
- Who updates Metadata and Business Glossary entries?
Meeting Scenario
Situation: Stewardship is assigned on paper, but data classifications remain inconsistent.
Possible response:
"We have stewardship assigned, but the recurring issue suggests the operational responsibility isn't clear. Let's define what the steward monitors, what triggers action, and when the owner needs to be involved."
Key Takeaways
- Data Stewards perform day-to-day governance.
- Owners are accountable; stewards operationalize standards.
- Stewardship does not require a dedicated job title.
- Governance should be lightweight enough to actually operate.
