9. Customers call a call center to make room reservations for a small chain of 42 motels
located throughout the southwestern part of the United States. Business analytics is
used to determine how and if the following performance metrics are related: time by
quarter, average time on hold (seconds) before a customer reaches a company
customer service representative, percent of time the customer inquiry is solved the
first time (called first pass quality) and customer satisfaction with the overall call
center experience.

10.* What is the average value of a loyal customer (VLC) in a target market segment if
the average purchase price is $75 per visit, the frequency of repurchase is six times
per year, the contribution margin is 10 percent, and the average customer defection
rate is 25 percent?
VLC = P*CM*RF*BLC, where P = the revenue per unit, CM = contribution margin

11.* Using the base case data in question 10, analyze how the value of a loyal customer
(VLC) will change if the average customer defection rate varies between 15 and 40
percent (in increments of 5 percent) and the frequency of repurchase varies between
3 and 9 times per year (in increments of 1 year). Sketch graphs (or use Excel charts)
to illustrate the impact of these assumptions on the VLC.
12.* What is the average defection rate for grocery store shoppers in a local area of a
large city if they spend $45 per visit, shop 52 weeks per year, the grocery store has a
8 percent gross margin, and the value of a loyal customer is estimated at $2,750 per
year?

times, but did not know how to analyze the data.
