Problems also occur in car setups. Occasionally, customers arrive to find that their
car is not set up right. A car may not have a global positioning system, as ordered, or a
car may be logged into the wrong slot on the lot so a customer could not find it. Sometimes, the general maintenance of the cars is not as good as it could be—a paper cup
may be found in the back seat area, or the gas tank may not be full—which also leads to
customer complaints. The depot manager blames it on poor training of the employees
doing auto maintenance and preparation. Some of these problems—the problem of poor
setups, for example, are internal problems that will not really get noted until you look at
a flow diagram that focuses on the subprocesses within the Rent Cars process.
