Governance
- Governed by
- Technology Council
- Review cadence
- Quarterly (March, June, September, December)
- Approval process
- Enterprise Architect drafts → Technology Council votes → published
- Staleness threshold
- Flagged if quarterly review missed
- Lifecycle
- Permanent — versions tracked, updated on technology change
- Escalation path
- Enterprise Architect → Technology Council → Steering Group
Inter-Type Relationships
- Standards provide guidelines for → Outlines, Designs
- Standards eventually shape → Landscapes
- Considerations influence selection of → Standards
- Visions guide selection of → Standards
