Data Flow Diagrams provide a clear understanding of the flow of data through the systems, processes, and users within your organization.

Examples of errors include forgetting to include a data flow or pointing an arrow in the wrong direction. A key reason why keeping data flow diagrams up-to-date is to address issues of system growth.

When evaluating a management information system, make sure the input data include the information you need and that they are transmitted securely to the servers.
