What is indicated by Intermediate Events in BPMN?

Intermediate Events in BPMN (Business Process Model and Notation) represent points in the process where changes occur. These events can indicate a variety of scenarios, such as the arrival of a message, the passage of a timer, or the occurrence of an error. They contribute to the dynamic aspects of a business process, showing how the flow can be affected at different points in time.

These events can facilitate decision-making processes, trigger specific actions, or signify transitions between different phases of an operation. This aspect of BPMN helps in illustrating the complexity of business processes, where events that occur during the execution of a process can significantly alter the flow and outcomes. By focusing on intermediate events, modelers can provide a clearer understanding of how various factors can influence operational workflows.

This understanding contrasts with other options, which focus on starting and ending points or simply showing information dependencies.
