System Data Flow Diagram

ea3-sysEA3 artifact A2.1 System Data Flow Diagram

The System Data Flow Diagram is better known as a ‘Data Flow Diagram’ and is intended to show the processes within a system that exchange data, and how those exchanges occur.  This artifact compliments the Business Process Diagram, and can be decomposed to show additional detail.

  1. Captures and describes system functions and the data flows between them.
  2. Documents system functional hierarchies.
  3. Primary purpose is to:
    • Develop a clear description of the necessary system data flows that are input (consumed) and output (produced) by each system
    • Ensure functional connectivity is complete
    • Support appropriate level of functional decomposition for additional detail
  4. Is the systems counterpart to the Business Process Model (IDEF-0 diagram).
