Scenario
A Telehealth platform serves both Patients and Physicians, who share common capabilities as an Authenticated User (signing in via SSO). Both Video Consultation and Async Chat Consultation are specialized forms of Conduct Consultation. Every consultation mandatorily includes Record Clinical Notes and Verify Insurance, and Verify Insurance itself mandatorily includes Log Audit Trail. Optionally, a consultation may be extended by Issue E-Prescription (which also interacts with the external Pharmacy Network system), and a Video Consultation may be extended by Escalate to Emergency Dispatch if a patient is in distress.
Objective
Model the complete Telehealth Use Case diagram combining Actor Generalization, Use Case Generalization, chained «include» dependencies, conditional «extend» hooks, and secondary system Associations.
