Scenario Exercise $1$: Manage Appointments Use Case Diagram

Description:

In the given scenario, the Manage Appointments use case has been specialized to include two use cases: Make Old Patient Appt and Make New Patient Appt. The Make Old Patient Appt use case extends its functionality with the Update Patient Information use case, while the Make New Patient Appt use case is specifically for new patients.

Actors:

$-$ Patient: An actor representing a general patient.

$-$ Old Patient: A specialization of the Patient actor for existing patients.

$-$ New Patient: A specialization of the Patient actor for new patients.
