SV-3: Systems-Systems Matrix
A SV-3 enables a quick overview of all the system resource interactions specified in one or more SV-1 Systems Interface Description models. The SV-3 provides a tabular summary of the system interactions specified in the SV-1 Systems Interface Description model for the Architectural Description. The matrix format supports a rapid assessment of potential commonalities and redundancies (or, if fault-tolerance is desired, the lack of redundancies).
The SV-3 can be organized in a number of ways to emphasize the association of groups of system pairs in context with the architecture's purpose.
The intended usage of the SV-3 includes:
- Summarizing system resource interactions.
- Interface management.
- Comparing interoperability characteristics of solution options.
The SV-1 concentrates on System resources and their interactions, and these are summarized in a SV-3. The SV-3 can be a useful tool for managing the evolution of solutions and infrastructures, the insertion of new technologies and functionality, and the redistribution of systems and activities in context with evolving operational requirements.
Depending upon the purpose of the Architectural Description, there could be several SV-3s. The suite of SV-3 models can be organized in a number of ways (e.g., by domain, by operational mission phase, by solution option) to emphasize the association of groups of resource pairs in context with the Architectural Description purpose.
The SV-3 is generally presented as a matrix, where the Systems resources are listed in the rows and columns of the matrix, and each cell indicates an interaction between resources if one exists. Many types of interaction information can be presented in the cells of a SV-3. The resource interactions can be represented using different symbols and/or color coding that depicts different interaction characteristics, for example:
- Status (e.g., existing, planned, potential, de-activated).
- Key interfaces.
- Category (e.g., command and control, intelligence, personnel, logistics).
- Classification-level (e.g., Restricted, Confidential, Secret, Top Secret).
- Communication means (e.g., Rim Loop Interface, Scalable Loop Interface).
DoDAF does not specify the symbols to be used. If symbols are used, a key is needed.
