The process "Model QA Process" uses 1 (IS) service as identified in the BPMN diagram analysis:

• AI driven model QA (Type: Service IS (Application), Stereotype: ApplicationISService)

This IS service is referenced by the process through a "required by" dependency relationship, as shown in the BPMN diagram.

The diagram visually demonstrates how the "Perform QA" task within the process connects to the AI-driven model QA service, indicating that this service is invoked during the quality assurance execution phase.
