An analytic approach is a much more research and data based approach, where two sets of information are derived and used to segment the market. The two approaches give the business an idea for the future profitability of a segment, and the tendencies and behaviours it portrays. The first approach gives them an idea on the future growth of the segment, and whether its investment outcome is worthwhile. This, therefore, will usually be done in advance. The second approach is more based around the observation of the buying behaviours of the segment and is more based around primary research.
