2) quick telephone response (qtr) was started several years ago to provide an outsource
telephone service for the growing number of small, specialty catalog mail-order
companies that commenced operations in recent years. since most of the calls are
received between 10 a.m. and 2 p.m., qtr began offering a telephone answering service
to attempt to fill the remainder of the day for its operators. however, as outsource
competition has recently increased, qtr analyzed its operations and concluded that it
should focus on its core business of providing service to its mail-order clients only. to
bring operating costs into line, qtr concluded that it should shed some of its full-time
operators and replace them with part-time operators in order to cover the peak mid-day
calling period.
weldon miller, director of the telephone response operations department, engaged a
consultant to assist in analyzing the situation and determining the number of full-time
and part-time employees that will be required to meet qtr’s variable operating schedule.
based on a study of one month’s activity they concluded that the number of daily orders
received for their specialty clients averaged 3,450 with the mid-day period averaging
2,250 orders. they calculated that there would be a need to retain twenty five (25)
full-time employees. they further developed two regression analyses. regression 1
relates to the average of 3,450 orders per day and regression 2 relates to the average of
2,250 peak mid-day orders. the data resulting from these analyses are presented below.
