Which process model notation relies heavily upon logical operators called "rules"?

The event-driven process chain (EPC) notation is designed to model business processes in a way that clearly represents the flow of events and decisions that drive those processes. A fundamental feature of EPCs is the use of logical operators, specifically rules, which allow for the depiction of complex decision-making scenarios.

In EPC, events trigger functions, and these functions can be linked with logical operators such as AND, OR, and XOR (exclusive OR). This incorporation of rules helps to determine how processes proceed based on different conditions and events. These logical rules provide clarity on how decisions within the process affect outcomes, which is essential for understanding and optimizing business workflows.

This emphasis on events and rules distinguishes EPC from other process modeling methods. For instance, flow charts primarily showcase sequential steps without the deeper representation of decision logic that EPC provides. UML mainly serves as a broader modeling language for software design and does not focus specifically on business processes or rules as in EPC. Integrated DEFinition Methods (IDEF) encompasses a variety of modeling approaches, focusing also on detailed system analysis rather than the event-driven nature with logical rules characteristic of EPC.

By leveraging logical operators effectively, EPC allows organizations to better model, analyze, and improve their business processes, making it a preferred choice when exploring
