1 EA Demonstration Study : Dissemination Forum – 8 June EA Views and Sub-views Patrick Bardet EA Unit

2 2EA Demonstration Study : Dissemination Forum – 8 June 2009 All View Programme (Project / Acquisition) View Programme View Capability (Strategic) View Operational View Service-Oriented View Systems View Technical (Standards) View Capability (Strategic) View Operational View Service-Oriented View System View Technical View Overview Definitions Capability Problem / Opportunity Goal Service Resource / System Data Information Process Information Exchange Organisation / Human Actor The high-level requirements for Enterprise change over time. The operational concept – operational roles, processes, scenarios; information flows. The services to support the operations, their interfaces, behaviour and policy. The solution specification – the resources providing the services. Sets the scope and context, provides a summary of findings. Technical Standard Implementation Guideline To support implementation – policy, standards, guidance, constraints. Milestones / Timing Projects / Activities Planning of programmes, projects, acquisitions to provide the required capabilities. Inter- connection Function EAEA Framework Proposal
