As you can see, each need set represents a related cluster of characteristics. In addition, however, consumers can be grouped (segmented) in terms of their similarity regarding the importance they place on the different need sets. For example, there is the "Basic" shopper segment that only cares about mall essentials; an "Enthusiast" shopper segment that cares about all the need sets with a particularly high emphasis on entertain ment; a "Serious" shopper who cares about brand-name merchandise and convenience; a "Destination" shopper who cares about mall essentails and brand-name merchandise; and a "brand" shopper who only cares about brandname merchandise. Clearly all shopper are not the same, and retailers must work hard to adapt to the differing need sets of different shopper segments.
