Which flow shape represents an automated system action that requires no human intervention?

The Utility shape is specifically designed to represent automated system actions that do not require any human intervention. This shape is used within Pega to include tasks that are performed automatically, such as data processing, calling external systems, or executing background operations without requiring user interaction. The flow can seamlessly continue to the next step after the utility action completes, making it integral for automation within a workflow.

In contrast, the other shapes serve different functions. The Subprocess shape is used to call and execute another process within the main flow, which may involve human tasks. The Decision shape is utilized to route the flow based on specific conditions and typically involves evaluating criteria that may depend on user input or data. The End shape signifies the conclusion of a flow and does not represent actions performed, automated or otherwise. Therefore, the Utility shape is the clear choice for depicting automated actions in Pega flows.
