What is the function of a "Gateway" in a process model?

The function of a "Gateway" in a process model is to direct the flow of execution based on conditions. Gateways are crucial components in process modeling as they help in making decisions within a workflow. They evaluate specific conditions or expressions and determine which path the process should take next based on the results of these evaluations.

For example, if a process has multiple possible next steps, a gateway can assess the current state of the process and direct it down the appropriate path. This decision-making capability is what allows for dynamic and flexible process flows, tailoring the execution to the specific circumstances at hand.

The other options describe functions that are not aligned with the primary purpose of a gateway. While terminating a process early is relevant to process control, it is not the role of a gateway. The initiation of a new process is usually handled by different elements in the process model, such as start events. Storing process data is typically managed by tasks or data storage elements, rather than a gateway. Hence, the function of directing the flow based on conditions is what distinctly characterizes a gateway in process modeling.
