Chapter 2 Getting Started with Business Process Modeling
The business process diagram (or Process Flow Diagram—PFD) allows you to detail the internal choreography of a process. You can analyze how sub-processes will be allocated to people, organizations or groups, the control flow of the process and how data flows through it, along with the implementation of your sub-processes. If you are using an orchestration engine, you can implement processes using one or more service providers.
In the following example the path of an order depends on whether it is a corporate order. The control flow passes through the Process Corporate Order process, then through the Check Book process, which checks the book availability in the Inventory resource. The check is done through the Inventory resource. Then the control flow path depends on whether it is an overnight delivery. If yes, the control flow passes through the Ship FedEx Overnight process with a message format specifying the format of the information exchanged (an administrative form for example). Then the shipment is confirmed. In any cases the control flow will go to Finish whether or not it is a corporate order.
