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. 
In addition, this model is useful in support of net-centric (service-oriented) implementation of services. This model can present a timeline of services evolve or are replaced over time, including services that are internal and external to the scope of the architecture. 
The intended usage of the SvcV-8 includes: 
- Development of incremental Acquisition Strategy
- Planning technology insertion
The SvcV-8, when linked together with other evolution Models such as CV-2 “Capability Taxonomy”, CV-3 “Capability Phasing” and StdV-2 “Standards Forecast”, provides a rich definition of how the Enterprise and its capabilities are expected to evolve over time. In this manner, the model can be used to support an architecture evolution project plan or transition plan. 
A SvcV-8 can describe historical (legacy), current, and future capabilities against a timeline. The model shows the structure of each resource, using similar modeling elements as those used in SvcV-1 “Service Interface Description”. Interactions which take place within the resource may also be shown. The changes depicted in the SvcV-8 DoDAF-described Model are derived from the project milestones that are shown in a PV-2 “Project Timelines” model. When the PV-2 Project Timelines model is used for capability acquisition projects, there is likely to be a close relationship between these two models. 
- The DoDAF descriptions in this website are very generic and are mostly taken from the DoDAF Architecture Framework website. Make sure you visit the actual website for the most update information and a more thorough explanation of each viewpoint.
- DoDAF Version 1.0, although outdated, has some good examples on how to construct AV’s, OV’s, and SV’s.
