Which shape indicates a decision point in a BPMN diagram?

In a BPMN (Business Process Model and Notation) diagram, a decision point is represented by a diamond shape. This is a standard convention used in BPMN to signify that a decision needs to be made based on certain conditions or criteria. When reaching this point in the process flow, a person or system evaluates the available options and determines which path the process should follow based on the outcome of that decision.

The use of the diamond shape clearly distinguishes the decision point from other elements in the diagram, such as tasks and events, which are represented by different shapes. This visual differentiation helps viewers quickly understand where decisions need to be made within the process, enhancing the clarity and comprehensibility of the BPMN diagram. Understanding this aspect is crucial for anyone working with BPMN, as effective process modeling relies on accurate representation of decision points to convey the flow of operations accurately.
