Note For matrices like OV-03 Operational Resource Flow matrix, SV-3 System to System matrix and SvcV-03a Systems to Services matrix, which are using Resource Flows, you can use the relevant diagrams to create the Flows, and later view the Flow as an intersection in the matrix. You can also create the flow by typing the Flow Name in the matrix cell, and later view the Flow updated in the diagram. Matrices using subtypes show the definition types (along with all its subtypes) in matrix rows and columns. For example, for OV-03 Operational Resource Flow matrix, it displays Performer (DM2) along with all its subtypes (Organization (DM2), Service (DM2), System (DM2), and so on) in rows as well as in columns.
