What are the three primary flow objects in BPMN?

The three primary flow objects in BPMN (Business Process Model and Notation) are indeed Events, Activities, and Gateways. These elements are fundamental to modeling processes effectively.

Events represent something that happens during the course of a business process. They can trigger activities or indicate the completion of tasks and can be categorized into different types based on their occurrence in the process lifecycle, such as start events, intermediate events, and end events.

Activities are the tasks or work that must be performed as part of the process. They can vary from simple tasks executed by a user to complex sub-processes that encapsulate additional workflows. This is where the actual work of the process occurs.

Gateways are decision points that control the flow of the process. They determine how the process will proceed based on certain conditions, enabling branching or merging of paths. This ensures that different outcomes can occur based on the parameters defined within the process.

In contrast, the other options include terms that do not align with the standard BPMN terminology for primary flow objects. Tasks are indeed part of activities but do not represent all types of activities. Similarly, controls, decisions, triggers, and actions do not accurately describe the main components of BPMN flow objects. Understanding these primary elements—Events,
