Event-driven process chains (EPC) are modeling tools used across industries for process analysis and design, developed in 1992. EPCs always start and end with events, incorporating functions and specific rules for connections represented as graphical connectors. ARIS Express is a free tool that allows users to model EPCs easily and share their designs in the ARIS community.

In an EPC, such rules are called 'OR', 'AND', or 'XOR' and are represented as graphical connectors. © Eva Klein
