    1. EA Modelling Guidelines From Capabilities to Services Version 2.5

    2. Strategic Direction The HA’s strategy is to move away from purchasing “islands of technology” to the procurement of modular, loosely-coupled, managed services.

    3. Historical system-based architecture

    4. Service-Oriented Architecture (SOA)

    5. The Service Model Aligning the Business and Technology Perspectives

    6. A Layered View (End Game)

    7. Relationship to Enterprise Architecture

    8. Relationship to MSP Blueprint and TOGAF Stages

    9. Relationship to ITIL Service Management

    10. Capability Mapping

    11. How the Capability view differs from other Business Architecture views Roots of contemporary performance problems are due to organisationally based operating model Process models (though an improvement) are not the optimal view or management layer, and they expose “how” business is done Capabilities manage “what service at what service level” – which is the most stable and concise level for design and management

    12. Separation of Concerns

    13. What is a Capability?

    14. Definition of a Capability

    15. Capability Mapping can provide much more relevant information

    17. A High Level Capability Map links Internal Capabilities with External Capabilities

    18. Each level of the Capability Map can be decomposed down into more detail

    19. Mapping against the EA Reference Model

    20. Example Capabilities-EARM Mapping

    22. Capability Mapping: the ideal foundation for SOA

    23. Capability Mapping as the business foundation for SOA

    24. The Service Model Aligning the Business and Technology Perspectives

    25. Inputs to the Service Model

    26. 10 steps to service definition

    27. How Capability Maps can help Service Design
