Understanding Consumer Behavior
Consumer behavior involves the actions a person takes in purchasing and using products and services, including the mental and social processes that come before and after these actions. The stages a buyer passes through in making choices about which products and services to buy are known as the purchase decision process. This process has five stages.
- Problem recognition: perceiving a need
 - Information search: seeking value
 - Alternative evaluation: assessing value
 - purchase decision: buying value
 - postpurchase behavior: Value in consumption or use
