What is the primary purpose of BPMN Activity Models?

The primary purpose of BPMN (Business Process Model and Notation) Activity Models is to create visual diagrams that depict business processes. These models provide a standardized way to visualize workflows and processes, making it easier for stakeholders to understand the flow of activities, decisions, and events within a business operation. By utilizing BPMN, organizations can map out their processes, identify inefficiencies, and communicate complex processes in a straightforward manner. This visualization helps facilitate discussions about process improvements and allows for clear documentation that can be easily shared among team members and departments.

Other options represent distinct functions or roles within an organization but do not align with the fundamental intent of BPMN. For instance, specifying database transactions involves a technical focus on data management rather than process visualization. Ensuring data integrity pertains to ensuring accuracy and consistency of data, which is a different concern. Analyzing customer relationships often requires different analytical tools more focused on customer data and behavior rather than process mapping. Hence, the emphasis of BPMN on visualizing business processes sets it apart as the correct answer in this context.
