Patricia Burger, the company president, authorized the customer service department manager, Tim, to study this problem and find a method to shorten the call-waiting time.

2. Mark, but I just realized that sometimes I simply don't understand what the custo- mer's problem
really is. I spend a lot of time trying to get him or her to explain it better. Often, I have to route it
to someone because other calls are waiting. RAVI: Perhaps we need to have more knowledge of
our products. TIM: Well, I think we've covered most of the major reasons why many customers
have to wait. It seems to me that we have four major reasons: the phones are short-staffed, the
receiving party is not present, the customer dominates the conversation, and you may not
understand the customer's problem. Next we need to collect some information about these
possible causes. I will set up a data collection sheet that you can use to track some of these
things. Mark, would you help me on this? Over the next two weeks, the staff collected data on
the frequency of reasons why some callers had to wait. The results are summarized as follows:
Reason and the total number:
Operators short-staffed - 172
Receiving party not present - 73
Customer dominates conversation - 19
Lack of operator understanding - 61
Other reasons - 10
From the above CASE, answer the following questions:
