How many maximum requests does the system retain and show for agents?

The correct answer indicates that the system retains and displays a maximum of 150 approved requests for agents. This is significant in workforce management because it allows agents to have a comprehensive view of the requests that have been successfully approved, which can include time-off requests, shift swaps, and other workforce-related requests. Managing approved requests effectively is crucial for maintaining workforce efficiency and ensuring that agents have access to their schedules and changes.

Having this number of approved requests visible aids in organizational transparency and helps agents to monitor their own requests and verify that they have been processed correctly. It ensures that agents can plan their time accordingly and understand their current workload or scheduled time off. This feature helps drive efficiency, reducing the time agents spend inquiring about their request statuses or the need to resubmit requests.

The other options, while they specify different types of requests, focus on pending, denied, or canceled requests, which do not contribute as directly to an agent's ongoing operational needs as the approved requests do. The retention of 150 approved requests presents a clear advantage in workforce management by allowing for better resource planning and self-management among agents.
