The SvcV-10c “Services Event-Trace Description” provides a time-ordered examination of the interactions between services functional resources. Each event-trace diagram should have an accompanying description that defines the particular scenario or situation. The SvcV-10c is valuable for moving to the next level of detail from the initial solution design, to help define a sequence of service …

The SvcV-9 “Services Technology and Skills Forecast” defines the underlying current and expected supporting technologies and skills. Expected supporting technologies and skills are those that can be reasonably forecast given the current state of technology and skills, and expected improvements or trends. New technologies and skills are tied to specific time periods, which can correlate …

The SvcV-10a “Services Rules Model” is to specify functional and non-functional constraints on the implementation aspects of the architecture (i.e., the structural and behavioral elements of the Services Model). The SvcV-10a describes constraints on the resources, functions, data and ports that make up the Service Model physical architecture. The constraints are specified in text and …

The SvcV-10b “Services State Transition Description” is a graphical method of describing a resource (or function) response to various events by changing its state. The diagram basically represents the sets of events to which the resources in the Activities respond (by taking an action to move to a new state) as a function of its …

The SvcV-7 Services Measures Matrix depicts the measures (metrics) of resources. The Services Measures Matrix expands on the information presented in a SvcV-1 “Services Interface Description” by depicting the characteristics of the resources in the SvcV-1 Services Context Description. Guide: DoDAF Architecture Framework Version 2.02 – Page 185 In addition, this model is useful in …

The SvcV-8 “Services Evolution Description” presents a whole lifecycle view of resources (services), describing how it changes over time. It shows the structure of several resources mapped against a timeline. [1] Guide: DoDAF Architecture Framework Version 2.02 – Page 187 In addition, this model is useful in support of net-centric (service-oriented) implementation of services. This …

Within an Architectural Description, the SvcV-4 “Services Functionality Description” documents service functions, the Resource Flows between those service functions, the internal system data repositories or service data stores, and the external sources and sinks for the service data flows, but not external to the Architectural Description’s scope. They may also show how users behave in …

The SvcV-5 “Operational Activity to Services Traceability Matrix” addresses the linkage between service functions described in SvcV-4 “Service Functionality DEscription” and Operational Activities specified in OV-5a “Operational Activity Decomposition Tree” or OV-5b “Operational Activity Model”. The SvcV-5 depicts the mapping of service functions (and, optionally, the capabilities and performers that provide them) to operational activities …

The SvcV-6 “Services Resource Flow Matrix” specifies the characteristics of the Service Resource Flows exchanged between Services. The focus is on resources crossing the service boundary. The SvcV-6 focuses on the specific aspects of the Service Resource Flow and the Service Resource Flow content in a tabular format. [1] Guide: DoDAF Architecture Framework Version 2.02 …

A SvcV-2 “Services Resource Flow Description” specifies the Resource Flows between Services and may also list the protocol stacks used in connections. A SvcV-2 is used to give a precise specification of a connection between Services. This may be an existing connection or a specification of a connection that is to be made for a …
