Actions, steps and connectors are represented in Process Charts by specific symbols, lines and arrows. A set of standard symbols and layout have been designed by the Business Process Model and Notation (BPMN). These are often used by process chart software and chart drawing programs, and makes the chart easier to understand when presented to other users.
