You can describe a company's processes using an EPC. It is based on the logical and chronological sequence of the activities to be carried out. In addition, a sequence of functions and resulting events is used. These lean processes can be supplemented by additional objects (organizational units, positions, roles, application systems, etc.) containing extended information. Thus, for example, a risk with the occurs at connection can be connected directly with a function in an EPC (in previous versions referred to as the risk-based approach). Or, another example, a control with the is carried out at connection can be directly connected to a function in an EPC (previously referred to as the control-based approach). The following model types can be assigned to an object type in an EPC:

EPCs can also be modeled as lean EPCs, that is, without organizational units, positions, and application systems. The relationships between these additional objects and a function are then modeled in a function allocation diagram, which is assigned to the function. The object and symbol types in the function allocation diagram are those that change a lean EPC into an extended EPC. These are:
