1. What Is Data Governance?

Data governance is the system of policies, roles, and processes that ensures data is managed as a strategic asset. It answers: Who owns this data? How fresh is it? Who can access it? What happens when it breaks?

Governance ≠ Bureaucracy

Good governance enables speed. It's not about blocking access — it's about making data trustworthy so teams can self-serve confidently.

2. Six Pillars of Data Governance

Data Quality

Measure completeness, accuracy, freshness, and consistency. Automate monitoring with tools like Great Expectations or Monte Carlo.

Stewardship & Ownership

Every dataset needs a named owner. Stewards are accountable for quality, documentation, and access policies within their domain.

Metadata Management

Centralize metadata in a catalog. Automate ingestion. Maintain a business glossary so terms like "revenue" mean the same thing everywhere.

Security & Privacy

Role-based access, encryption, PII classification, and audit logs. Essential for GDPR, CCPA, HIPAA, and SOX compliance.

Compliance

Map regulatory requirements to data assets. Automate data retention policies. Maintain lineage for audit trails.

Lifecycle Management

Define how data is created, stored, archived, and deleted. Prevent unbounded storage costs and stale data accumulation.

4. Implementation Roadmap

Quarter 1: Foundation

  • Get executive sponsorship and define governance charter
  • Identify top 5 critical data domains
  • Assign data owners and stewards
  • Deploy a data catalog (DataHub, Atlan, or similar)

Quarter 2: Quality & Access

  • Implement data quality monitoring for critical datasets
  • Define access policies and role-based controls
  • Classify PII and sensitive data
  • Build lineage for top pipelines

Quarter 3-4: Scale & Automate

  • Expand governance to all data domains
  • Automate compliance checks in CI/CD
  • Launch self-serve data marketplace
  • Report governance KPIs to leadership quarterly
