Which process model notation uses rule objects such as "AND," "OR," and "Exclusive OR"?

The correct answer is Business Process Model Notation (BPMN). BPMN is designed specifically for modeling business processes and includes a variety of elements to represent complex process flows. One of its key features is the use of gateway symbols to depict decision points in the process. These gateways can represent different types of logical conditions, including "AND," "OR," and "Exclusive OR" (XOR), allowing for clear and effective representation of branching paths in business processes.

This capability helps process stakeholders understand where different decision pathways may occur based on specific conditions, making BPMN a versatile and widely used notation in process modeling. The ability to visually represent these logical relationships enhances clarity for individuals analyzing or executing the process.

While Event-driven process chains (EPC) and other choices like Unified Modeling Language (UML) and Standardized Process Model (SPM) may employ their own methods for representing processes, they do not use these specific logical operators in the same systematic way as BPMN does.
