Glenn Dental Clinic provides general dental care to residents of Philadelphia on a walk-in basis. The clinic has started receiving complaints from patients that the waiting time is too long and has asked you to investigate whether this problem can be solved. Upon arrival, customers receive a form from the receptionist and fill out relevant information such as personal health records and insurance provider The form is then handed back to the receptionist who enters the information into the computer system for the dentist to see. A dental assistant then takes an X-ray from the patient. A dentist then performs the checkup and discusses any issues with the patient. Based on conversations with staff members at the clinic, you have obtained the following information on the process: It takes about 5 minutes for a customer to ll out the paperwork. Entry of information on the papenNork into the system and verication with past records takes another 5 minutes for a receptionist. There are two receptionists.
