It defines consumer behavior and outlines several important models and concepts, including product categories, the product life cycle (PLC), and the customer decision model (CDM). It also discusses problem solving approaches, complex consumer factors, and provides some critique of generalizations and outdated examples used in the book. While noting limitations, it acknowledges the book's practical implications and interdisciplinary approach involving psychology.
