Business process diagram can be used in visualizing a business workflow. When you want to identify the use cases of a system, business process diagram can be a useful reference in that it lets you derive system goals by considering what the stakeholders do day-by-day, represented by tasks and sub-processes. In Visual Paradigm, you can create use cases from BPMN tasks and sub-processes with the use of Model Transitor.
