5. Service Oriented Architecture • Capability - Architectural Approach • Integration of Functions within Systems across Platforms • Services • System Functions and their Quality of Service • Integration of services - Independent of implementation Network Enabled Capability Through Innovative Systems Engineering

6. Abstract Service Layer • Loose Coupling for dynamic resource selection and dynamic integration • Dependability: fault tolerance, evolution, availability • Breaking stovepipe model of platform integration Network Enabled Capability Through Innovative Systems Engineering

7. Loosely Coupled Capability • Military Capability is defined in the Problem Domain and is defined during Concept phase • Assessment, Development and Manufacture phases fix the solution • Retain the Problem definition during the In–Service phase • Dynamic integration during In-Service by selecting components that match capability functions to the Problem Network Enabled Capability Through Innovative Systems Engineering
