Segmentation involves finding out what kinds of consumers with different needs exist. In the auto market, for example, some consumers demand speed and performance, while others are much more concerned about roominess and safety. In general, it holds true that “You can’t be all things to all people,” and experience has demonstrated that firms that specialize in meeting the needs of one group of consumers over another tend to be more profitable.
Generically, there are three approaches to marketing. In the undifferentiated strategy, all consumers are treated as the same, with firms not making any specific efforts to satisfy particular groups. This may work when the product is a standard one where one competitor really can’t offer much that another one can’t. Usually, this is the case only for commodities. In the concentrated strategy, one firm chooses to focus on one of several segments that exist while leaving other segments to competitors. For example, Southwest Airlines focuses on price sensitive consumers who will forego meals and assigned seating for low prices. In contrast, most airlines follow the differentiated strategy: They offer high priced tickets to those who are inflexible in that they cannot tell in advance when they need to fly and find it impractical to stay over a Saturday. These travelers—usually business travelers—pay high fares but can only fill the planes up partially. The same airlines then sell some of the remaining seats to more price sensitive customers who can buy two weeks in advance and stay over.
