Detailed Explanation:
The correct answer is C. Volume of business.
A “frequent buyer” program is designed to recognize and encourage customers who purchase often or in higher amounts. The most relevant segmentation factor for such a program is the customer’s volume of business, because it reflects the level and frequency of purchasing activity.
Why C is correct:
Volume of business helps identify:
high-purchase customers,
repeat buyers,
customers generating strong sales activity,
and those most suitable for loyalty or frequency-based programs.
From a Quality Management Excellence perspective, segmentation should be based on factors that directly support the intended business objective. Since the objective here is to identify frequent buyers, purchase volume is the most relevant measure.
Why the other options are not correct:
A. Geography
Location may be useful for distribution or market planning, but it does not directly identify frequent buyers.
B. Service requirements
Service requirements may help design support models, but they do not directly classify customers by buying frequency.
D. Demographics
Demographics may help in marketing analysis, but they are less direct than purchase volume for building a frequent buyer program.
Quality Management Excellence interpretation:
Effective segmentation uses measures that are directly tied to the purpose of the program. Best practice is to segment customers by purchasing behavior when designing loyalty, retention, or frequency-based initiatives.
