The event-Driven Process Diagram can be created using EdrawMax as it has hundreds of predefined templates that let you create the Event-Driven process chain. As illustrated below, an event-driven process (EPC) is a type of flow chart used to configure enterprise resource planning execution and business process improvement. The event-driven process diagram method lays out business process workflows. It should be noted here that the EPC is an ordered graph of events and functions. It provides various connectors that allow alternative and parallel execution processes—the EPC diagram usages of logical operators, such as OR, AND, and XOR.
