Chapter 5, Problem 1P
Bill’s Barbershop has two barbers available to cut customers’ hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow in Figure 5.9 shows that all customers go through Steps Bi and B2 and then can be served at either of the two barbers at Step B3. The process ends for all customers at Step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer.
- How long does it take the average customer to complete this process?
- What single activity is the bottleneck for the entire process?
- How many customers can this process serve in an hour?

The School of Dentistry at Penn provides general dental care to residents of Philadelphiaon a walk-in basis. Upon arrival, customers first provide health-relevant informationsuch as personal health records and insurance provider to a receptionist who entersthe information into the computer system for the dentist to see. A dental assistant thentakes an X-ray of the patient. A dentist then performs the checkup and discusses anyissues with the patient. Depending on the day, patients might have to wait at any of theseresources. This concludes the process.
