Document Summary

Process documentation: system flowcharts present a comprehensive picture of the management, operations, info systems, and process controls embodied in business processes. Preparing systems flowcharts: divide the flowchart into columns. One column for each internal entity and one for each external entity. Label each column: flowchart columns should be laid out so that flowchart activities flow from left to right. But, minimize cross lines and connectors: flowchart logic should flow from top to bottom and from left to right. For clarity, put arrows on all flow lines: try to keep the flowchart on one page. With multiple pages, use off-page connectors: within each column, there must be at least one manual process, keying operation, or data store (cid:271)etwee(cid:374) do(cid:272)u(cid:373)e(cid:374)ts. Documenting enterprise systems: moving from a file-based system to an enterprise database changes the systems flowchart. An enterprise database replaces transaction and master data. Other flows may change depending on the system implementation.
