Evaluate the appropriateness of each of the different interview and survey-based primary research methods for:

(a) investigating the buying criteria used by B2B purchasers;

(b) defining the attitudes of a target market towards a brand of breakfast cereal;

(c) profiling purchasers of small electrical goods; and

(d) measuring levels of post-purchase satisfaction among customers.

Clearly define any assumptions you make about each of the situations.
