The OV-4 organizational relationships chart is a hierarchy diagram that describes the relationships between organizational resources.
You can model the following elements using the OV-4 diagram:
•The hierarchy of Organization Types, the Organizational Posts that report to Organizational Types, and the Roles that Organizational Posts perform.
•The hierarchy of Actual Organizations, and Actual Posts that report to Actual Organizations.
•Relationships between Organization types. These relationships can include command and control, coordination relationships (which influence what connectivity is needed), and many others, depending on the purpose of the architecture. These relationships are important to show in an operational view of architecture because they illustrate essential roles and management relationships.
