The SV-8, or System View 8, is a model used in systems engineering to represent the operational view of a system. It provides a high-level overview of how different components interact within a system, focusing on the relationships and functions rather than the technical details. This helps stakeholders understand the system's purpose and functionality. In the context of the Department of Defense, the SV-8 is part of the Unified Architecture Framework and is often used in conjunction with other models like the SV-1 and SV-2. It aids in visualizing the system's operational environment and supports decision-making processes.
