Determinance Model (of Brand Evaluation)

a model used in the study of consumer decision processes to evaluate alternative brands. The idea that consumers, about to make a purchase, will not be swayed in their product choice by any one product attribute, no matter how important, if all products possess the same amount of the attribute. Thus, the decision is made on the basis of a less important attribute. Other models of brand evaluation include the expectancy-value model, ideal brand model, conjunctive model, lexicographic model and determinance model.
