AI models aren't set-and-forget. They need governance from development to retirement. Here's what that actually means.

The Model Lifecycle

Every AI model goes through phases. Governance means controls at each one:

PhaseGovernance Focus
DevelopmentStandards, documentation, testing
ValidationPerformance checks, bias testing
DeploymentApproval process, rollback plan
MonitoringDrift detection, performance tracking
RetirementSunset process, replacement

What Model Governance Includes

Development Standards

  • Data requirements: What data can be used, how it's sourced
  • Documentation: Model cards, training data records
  • Version control: Tracking changes to models and data
  • Testing requirements: What tests must pass before deployment

Validation Process

  • Performance benchmarks: Accuracy, speed, reliability
  • Bias testing: Fairness across demographic groups
  • Edge cases: How model handles unusual inputs
  • Security review: Vulnerabilities, attack vectors

Deployment Controls

  • Approval workflow: Who signs off on production deployment
  • Rollback plan: How to revert if issues emerge
  • Integration testing: Works with existing systems
  • User communication: Notifying affected teams

Ongoing Monitoring

  • Model drift: Performance degrading over time
  • Data drift: Input data changing from training data
  • Usage patterns: How the model is actually being used
  • Error rates: Failures, edge cases, exceptions

Retirement Process

  • Trigger criteria: When to retire a model
  • Replacement: Transition to new model
  • Documentation: Archive for compliance
  • Communication: Notify users of change

Who Owns Model Governance?

RoleResponsibility
Data Science TeamTechnical implementation, testing
Business OwnerUse case decisions, risk acceptance
Compliance/LegalRegulatory requirements, risk review
IT/OperationsDeployment, monitoring infrastructure
Governance CouncilPolicy, escalated decisions

Model Documentation Requirements

Every model should have:

  • Model card: Purpose, limitations, performance
  • Training data record: Sources, preprocessing, bias checks
  • Test results: What was tested, outcomes
  • Approval trail: Who approved what, when
  • Monitoring plan: What metrics, what thresholds
  • Retirement criteria: When to replace

Regulatory Considerations

Depending on industry and location:

  • EU AI Act: Risk classification, transparency requirements
  • Industry regulations: Healthcare, finance, etc.
  • Data privacy: GDPR, CCPA, training data consent
  • Audit requirements: Documentation for examination

Signs You Need Better Model Governance

  • Models deployed without documentation
  • No one knows which models are in production
  • Model failures surprise the team
  • No process to retire outdated models
  • Bias or fairness issues discovered too late
  • Regulators asking questions you can't answer
