TOGAF Enterprise Architecture Skill

This skill implements enterprise architecture patterns based on the TOGAF Architecture Development Method (ADM).

When This Skill Activates

• Designing enterprise-scale systems
• Making architectural decisions
• Creating technology-agnostic specifications
• Implementing capability-driven architecture
• Planning large-scale system migrations

Core Principles

1. Principles Over Technologies

Focus on capabilities, not specific tools:

• Business Process Automation (not "use Kubernetes")
• Real-Time Decision Making (not "use TensorFlow")
• Multi-Cloud Interoperability (not "use AWS Lambda")

2. Capability-Driven Design

Define systems by what they accomplish:

capabilities:
  - Business Process Automation
  - Real-Time Decision Making
  - Multi-Cloud Interoperability
  - AI Integration
  - Compliance Management

3. Modularity & Replaceability

All components should be:

• Loosely coupled
• Independently deployable
• Replaceable without re-architecture

4. Technology Agnosticism

Specifications should survive technology changes:

• Define interfaces, not implementations
• Focus on outcomes, not tooling
• Enable future innovation

Governance Framework

Review Cycles

• Quarterly: Architecture effectiveness review
• Annual: Full compliance and security audit
• Continuous: Automated monitoring and alerting

Compliance Standards

• ISO 27001 (Information Security)
• GDPR (Data Protection)
• SOX (Financial Transparency)
• HIPAA (Healthcare Data)

Best Practices

1. Start with Capabilities: Define what, not how
2. Maintain Loose Coupling: Independent deployability
3. Ensure Auditability: Log all architectural decisions
4. Plan for Change: Assume technologies will evolve
5. Govern Consistently: Apply standards uniformly
6. Monitor Continuously: Real-time architecture health
