Example Diagram

While there are four diagrams that make up the standard, Business Process Diagrams are the most ubiquitous and resemble traditional flowcharts. You use them to describe or specify business, technology or engineering work flows and their simple but expressive graphical elements are for the most part universally understood by most stakeholders. You can keep diagrams simple and when combined with Decision Model and Notation models straight through processes can be achieved, ensuring the diagrams are free of visual clutter. You use Business Process diagrams to describe sequences of Activities and Tasks controlled by Gateways that act like traffic cops, controlling the flow. You can add Pools and Lanes, commonly called swimlanes, to represent the participants who carry out the Activities or Tasks.
