Make a Use Case Diagram:

Device Assignment Module Paul really wants a clear view of device assignment. In particular, he wants his staff to be able to use the system to record to whom a device is assigned. For example, on March 1, 2018, Jane Smith was provided a device with the tag ID 22335. He wants the system to record all the information. Specifically, the staff should be able to use the system to indicate that the device has been picked up by Jane at the pickup time (date and time). And the system shall record Janes signed signature as a proof.

If the employee David needs a loaner for the malfunctioning device he is using, he would file a loaner request using the AMS. With the full inventory information in the system, David shall be able to see what is available in inventory and pick one he likes. After receiving the request, the staff would prepare the requeste

d device, note in the system when the device is ready for pickup and send the notification to David. Upon receiving the notification, David needs to return in person the malfunctioning device, for which the staff will first update the status in the AMS, indicate the time of receipt of the device and reasons for return.

Before giving the loaner to David, the staff will need to indicate in the system the pickup time. David will then add his signature; the staff will update the status of the loaner request to fulfilled as well as the status of the loaner (i.e., pickedup)

Once a replacement arrives, the staff will create a record of the replacement first in the AMS and then notify David to pick up the replacement. David will then return the loaner, and pick up the replacement. His signature is required for the replacement pickup and loaner return, and the staff needs to show the time of the return/pickup and update the status of both devices.

After carefully reviewing the requirements of two modules, Paul seems to be convinced that the AMS is the solution for the inefficiency faced by his department
