Title
SV-3 Systems-Systems Matrix Subview
Version & Date
1.6 See DNDAF Release History
Introduction
The SV-3 subview is part of the DNDAF System View.
The System View-3 (SV-3): Systems-Systems Matrix is required to represent the systems interrelationships, interdependencies and interconnections inside and between the nodes as defined in OV-2 for the architecture project.
The Systems-Systems Matrix can be organized in a number of ways (e.g., by domain, by operational mission phase) to emphasize the association of groups of system pairs in context with the architecture’s purpose. The Systems-Systems Matrix can be a useful tool for managing the evolution of systems and system infrastructures, the insertion of new technologies and functionality, and the redistribution of systems and processes in context with evolving operational requirements.
Purpose
The Systems-Systems Matrix sub-view allows an overview of interface characteristics presented in potentially several Systems Interface Description (SV-1) diagrams. The matrix form can support an assessment of potential commonalities and redundancies (or, if fault-tolerance is desired, the lack of redundancies). This sub-view provides comprehensive information about systems interdependencies.
Background
The existence of disparate and heterogeneous systems within DND/CF makes it very difficult to provide an optimal support and accurate analysis of the current state. Therefore planning and developing new approaches for the desired future state is very complex and difficult to manage. The systems interdependencies representation is addressed by SV-3. Therefore planning and developing new capabilities or revealing the existing ones is facilitated through the content of the SV-3 sub-view, which represents a matrix of systems interdependencies.
Description
Definition
The Systems-Systems Matrix provides detail on the interface characteristics described in the Systems Interface Description for the project architecture, arranged in matrix form.
Detailed Description
The Systems-Systems Matrix is a summary description of the system-system interfaces identified in the SV-1 Systems Interface Description. The Systems-Systems Matrix is similar to an “N2”-type matrix where the systems are listed in the rows and the columns of the matrix, and each cell indicates a system pair interface, if one exists. Many types of interface information can be presented in the cells of a Systems- Systems Matrix whereas a simplistic representation is given below.
The system-system interfaces can be described by using a number of different symbols and/or colour-coding that depict different interface characteristics, for example:
- Status (e.g., existing, planned, potential, deactivated)
- Purpose (e.g., C2, intelligence, logistics)
- Security Classification level (e.g., Secret, TS)
- Standard
- Key Interface
