Three types of data are used: facts, opinions, and motivational information. The types of data required are partly identified by the nature of the problem to be solved. For instance, if the problem relates to production and inventory scheduling, the facts that are needed relate to market and sales potential. On the other hand, if the problem revolves around the choice between two new products, the opinions of potential customers are important considerations. Finally, if a problem involves the choice of an appropriate selling appeal, buyers' motivations are probably be most important. Facts are quantitative or descriptive information that can be verified. Opinions are ideas relating to a problem that are expressed by people involved in the solution. Motivations are basic reasons, recognized or unrecognized, that explain action. They are extremely difficult to discover.
