True or False

2) A catalog company has one department for taking customer orders and another for handling complaints. Currently, each department has a separate telephone number served by two customer service representatives (CSRs). Calls come into each department at an average rate of one call per minute. Each representative takes, on average, 1.5 minutes to serve a customer.

Management has proposed merging the two departments and cross-training all workers. The projected new department would have a single telephone number served by four CSRs that handle both customer orders and complaints, whose service times, after a bit of experience, would again average 1.5 minutes per call. With the new system, the average waiting time of callers will

a) decrease b) increase c) stay the same d) not enough information

3) Pooling multiple waiting lines to a single line helps to reduce the utilization of servers.
