When a patient phones to make a new appointment or change an existing one, the Medical Berjaya Clinic receptionist searches through the appointment file for an open slot. The appointment is scheduled once a suitable time for the patient has been identified. If the patient is a new patient, the patient file contains an incomplete entry. When the patient arrives for the appointment, the complete information will be obtained. A postcard reminder is routinely mailed by the receptionist to each client. Because appointments are frequently scheduled months in advance, the receptionist sends each patient a reminder postcard two weeks before to his or her appointment. FIGURE Q1 (b)
