Which of the following are considered connecting objects in BPMN?

In Business Process Model and Notation (BPMN), connecting objects are crucial for illustrating the flow of processes and the interactions between them. Sequence flow is one of the primary ways to connect different activities within a process model. It represents the order in which tasks, events, and gateways are performed, essentially mapping out the flow of the process from one activity to another.

Using sequence flow allows for a clear understanding of how a process progresses, delineating the path from start to finish. This ensures that anyone engaging with the process model can easily follow the logical sequence of activities. The significance of sequence flow becomes particularly evident in complex processes where multiple activities and decisions are involved, as it helps to clarify the relationships and dependencies between various elements.

While the other options, such as message flow and association, also serve important functions in BPMN, they have different roles. Message flow indicates the flow of messages between participants in a collaboration, while association is used to link artifacts or text annotations to flow elements. However, sequence flow specifically concerns the direct progression of tasks within the same process, making it a fundamental connecting object in BPMN.
