Final answer:
Orchestration in BPMN refers to the execution of business processes within a single organization. Collaboration represents the interactions between participants.
Choreography, not orchestration, covers interactions between participants with message flows.
Step-by-step explanation:
In the context of Business Process Model and Notation (BPMN), the interaction between different participants is not typically referred to as orchestration.
Rather, orchestration describes the controlled execution of business processes within one organization, focusing on the process flow. The term for the interaction between different participants or business entities in BPMN is called collaboration.
Collaboration diagrams show how multiple participants (organizations, departments, etc.) interact with each other to fulfill a goal or process. In contrast, choreography is used to define the interactions between different participants or business entities, highlighting the message flows between them without central control.
