- Understands the purpose of EA within the organisation at a high level.
Level 2 (Assist)
- Assists enterprise architects by collecting and organizing information about existing applications, technologies, or business processes.
- Helps create or update simple architectural diagrams (e.g., context diagrams, basic component diagrams) using standard templates and tools.
- Supports the maintenance of the EA repository by entering or validating data under guidance.
Level 3 (Apply)
- Develops specific architectural views (e.g., application interaction diagrams, technology component models) for projects or systems within a defined scope.
- Assesses proposed solutions for alignment with relevant EA standards, reference models, and patterns.
- Documents architectural decisions and designs according to EA guidelines.
Level 4 (Ensure)
- Leads the definition of solution architectures for significant projects, ensuring they are robust, scalable, secure, and aligned with overall EA strategy.
- Develops and maintains domain-specific architectures (e.g., business capability maps, application integration patterns, technology roadmaps).
- Conducts architecture reviews and provides guidance to project teams to ensure compliance with EA standards.
Level 5 (Strategise)
- Develops, maintains, and governs the organisation's overall enterprise architecture framework, methodology, principles, and standards.
- Creates and communicates the future-state EA vision and strategic technology roadmaps.
