Process flow diagrams
Business process modeling is carried out using process flow diagrams.
The purpose of the process flow diagram is to depict all models and mappings related to a process. Process flow diagrams show sequential flows of control between activities and may utilize swim lane techniques to represent ownership and realization of process steps. For example, the application that supports a process step may be shown as a swim lane. In addition to showing a sequence of activities, process flows can also be used to detail the controls that apply to a process, the events that trigger or result from completion of a process, and also the products that are generated from process execution. Process flow diagrams are useful in elaborating architecture with subject specialists, as they enable the specialist to describe how the job is done for a particular function. Through this process, each process step can become a more fine-grained function and can then in turn be elaborated as a process.
Process flow diagrams describe the internal functioning of processes. Expressed using the BPMN standard, they describe the sequence of tasks, the entities responsible for these tasks and the information exchanged.
Note that in this diagram, we find previously defined roles (Customer), corresponding to lines (responsibility for tasks), business units (sales department, administrative departments) and business entities (Order). A business process therefore completes the attributions of a role or a department.
