The level of experience and knowledge a buyer or buying organization possesses
relevant to a given purchasing decision is a primary determinant of the time and
resources the buyer will allocate to that purchasing decision. The level of a buyer’s
existing experience and knowledge has been used to categorize buyer behavior
into three types of purchasing decisions: straight rebuys, modified rebuys, and new
tasks. As summarized in Exhibit 3.6, selling strategies should reflect the differences
in buyer behaviors and decision-making characteristic of each type of buying
decision.
