The SV-2, or System View 2, is a type of model used in systems engineering to represent the operational aspects of a system. It provides a visual depiction of how different components interact and work together to achieve specific goals. This model helps stakeholders understand the system's functionality and the relationships between its parts. In the context of Department of Defense architecture frameworks, the SV-2 is part of a broader set of views that include other models like SV-1 and SV-3. These views collectively aid in the analysis, design, and management of complex systems, ensuring that all elements are aligned with the overall objectives.
