Wilson (1998) purpose that segmenting the market is a way to better allocate a company’s resources and satisfy their customers as well as sustain a competitive advantage. In the market there are increasing competition and globalization where industrial segmentation is considered to be a complex process. Earlier consumer- and industrial- companies have used similar demographic and socioeconomic variables when segmenting the market, but this has changed.
