How do consumers, organizations, and researchers make buying decisions?

"Buyer behavior is what consumers and businesses do in order to buy and use products. The consumer purchase decision-making process consists of the following steps: recognizing a need, seeking information, evaluating alternatives, purchasing the product, judging the purchase outcome, and engaging in post-purchase behavior. A number of factors influence the process. Cultural, social, individual, and psychological factors have an impact on consumer decision-making. The business purchase decision-making model includes the following steps: need recognition, setting specifications, information search, evaluation of alternatives against specifications, purchase, and post-purchase behavior. The main differences between consumer and business markets are purchase volume, number of customers, location of buyers, direct distribution, and rational purchase decisions. Companies learn more about their target markets by conducting marketing research—the process of planning, collecting, and analyzing data relevant to a marketing decision. Survey research is a marketing research method in which data is gathered from respondents, either in person, by telephone, by mail, at a mall, or through the internet to obtain facts, opinions, and attitudes."
