+# Data Steward
+
+## 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.
+
+## How It Fits Into the Bigger Picture

+
+## 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.
