Creating NSV-4 Systems Functionality diagrams for NAF 1.0
The systems functionality diagram, also called the data flow diagram (DFD), describes the flow of data among system functions, and the relationships between systems or system functions and activities at nodes. The NSV-4 diagrams can model both the present process and the future process, depending upon the project requirements.
