An important part of the marketing process is to understand why a customer or buyer makes a purchase. Without such an understanding, businesses find it hard to respond to the customer needs and wants. Marketing theory traditionally splits analysis of buyer or customer behavior into two broad groups for analysis – consumer buyers and industrial buyers. Consumer buyers are those who purchase items for their personal Consumption. Industrial buyers are those who purchase items on behalf of their business or organization. If a marketer can understand these customer responses better than the other competitors then it is a potentially significant source of competitive advantage.
