A program structure diagram in software engineering is a diagram which shows the breakdown of a system to its lowest manageable levels. In the design stage, the diagram is drawn and used by programmers as a way for the client and the various software designers to communicate.
Program structure diagram depicts the size and complexity of the system, and number of readily identifiable functions and modules. Program structure diagrams are used for procedural programs to illustrate the linkages between modules, flow of data, and control or exception information about a program in a visual format.
