1. What is the labor utilization for Giorgio, Carlo, and Guido in percent?
2. What is the utilization of Taddeo?

Westlake Custom Car Detail (WCCD) provides detailing (intensive car cleaning) services to antique and collector cars. Taddeo D'Andrea, the owner of the establishment has an online webpage which schedules appointments for car owners so that the arrival rate of cars at WCCD never exceeds its process capacity, (i.e. it's run as a just-in-time process). Taddeo has asked you, as a fellow UT BBA alum, to take a look at his process and make recommendations about how to improve it. During the process, Taddeo greets the clients, asks for some background information, and then directs the car to one of the detailers. The client is sent to a waiting room while the bill is prepared by Caterina. Taddeo then collects the payment himself. After both the payment is collected and the detailing completed, Maria guides the client to the car and says goodbye. The first thing you do is document the process flow with a process flow diagram, which is shown below. The next thing you do is perform analysis of the common operations metrics as shown in the sub-problems below. Note that each client brings exactly one car to WCCD, and that 3 clients arrive per hour on average
