# Change Management

Implement structured change management processes covering change classification, CAB workflows, emergency change procedures, and automation for compliance with SOC 2, ITIL, and regulatory frameworks.

## Change Classification

```yaml
change_types:
  standard:
    risk: Low
    approval: Pre-approved (no per-change approval needed)
    lead_time: None (within maintenance window)
    examples:
      - Routine patching within tested patch sets
      - Certificate rotation with established procedure
      - Scaling operations (adding/removing instances within limits)
      - Pre-approved configuration changes
      - Log rotation and archival
    requirements:
      - Change must match an approved Standard Change template
      - Automated testing must pass
      - Documented rollback procedure exists
      - Within defined maintenance window

  normal_low:
    risk: Low
    approval: Peer review (1 approver)
    lead_time: 2 business days
    examples:
      - Non-critical configuration changes
      - Feature flag toggles
      - Documentation updates to production systems
      - Adding monitoring dashboards or alerts

  normal_medium:
    risk: Medium
    approval: Team lead + peer review (2 approvers)
    lead_time: 5 business days
    examples:
      - Application deployments with new features
      - Database schema changes (non-breaking)
      - Network rule modifications
      - Integration endpoint changes
      - Dependency version upgrades

  normal_high:
    risk: High
    approval: CAB review required
    lead_time: 10 business days
    examples:
      - Infrastructure migrations
      - Breaking database schema changes
      - Major version upgrades (OS, runtime, database engine)
      - Changes to authentication or authorization systems
      - Multi-service coordinated deployments
      - Changes affecting data processing or compliance controls

  emergency:
    risk: Variable
    approval: Emergency CAB (minimum 2 approvers from on-call)
    lead_time: None (immediate implementation)
    examples:
      - Security vulnerability remediation (active exploitation)
      - Production outage resolution
      - Data integrity emergency fixes
      - Regulatory compliance deadline fixes
    requirements:
      - Retroactive full documentation within 48 hours
      - Post-implementation review required
      - CAB retroactive review at next meeting
```
