What is the main purpose of Groups in BPMN artifacts?

The primary purpose of Groups in BPMN (Business Process Model and Notation) artifacts is to organize tasks or processes. Groups are visual elements that allow modelers to cluster related activities or elements within a process without affecting the sequence of the flow or the execution of the process itself. This organizational feature helps in improving the readability and the structure of complex diagrams, making it easier for stakeholders to understand how various tasks relate to one another.

By using Groups, analysts can encapsulate related tasks, which aids in both design and communication. They serve a functional role in the modeling space by delineating sections of a business process, facilitating better organization and providing clarity to the model without altering the actual flow or interactions in the BPMN diagram. This characteristic distinguishes Groups from other elements in BPMN, such as message flows or decision points, which have specific functional intentions in the process.
