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
