What is the primary function of interaction operands in system modeling?

Interaction operands play a crucial role in system modeling, particularly in the context of specifying control logic within interactions between system components. They help define how different parts of a system interact based on certain conditions, enabling the modeler to delineate the sequence of operations or how data flows between participants in a scenario.

This function is fundamental, as it allows designers to articulate the conditions under which various actions occur and how control is transferred during these interactions. By accurately modeling this control logic, stakeholders can better understand the dynamic aspects of the system, ensuring it meets the required operational functionality while also allowing for effective troubleshooting and optimization during the design process.

The options related to event occurrence conditions, defining system architecture, and illustrating user behavior interactions, while important aspects of system modeling, do not capture the specific role of interaction operands in detailing the flow and control of actions within interactions. Instead, these elements focus on broader system characteristics or user behaviors rather than the precise control logic that interaction operands provide.
