The document outlines the key steps in a consumer's decision-making process: need recognition, information search, evaluation of alternatives, purchase and consumption, and post-purchase evaluation. It discusses factors that influence each step, including psychological factors (motives, attitudes, perceptions), social factors (family, culture), situational factors (environment at time of purchase), and elements of the marketing mix (product, price, place, promotion). Understanding the complex consumer decision process can help marketers develop effective strategies to meet consumer needs and influence purchase decisions.
