At the highest level we have chosen to categorize decisions into three major types: consumer decision making, business decision making, and personal decision making. The buying decision process is the decision-making process used by consumers regarding the market transactions before, during, and after the purchase of a good or service. It can be seen as a particular form of a cost–benefit analysis in the presence of multiple alternatives.

The 5 stages which a consumer often goes through when they are considering a purchase: problem or need recognition,information search,evaluation of alternatives, purchase, and post-purchase behavior.
