Consumer behavior is studied based on concepts from psychology, sociology, anthropology, marketing, and economics. It is important to study consumer behavior because customers can no longer be taken for granted. Failure rates of new products are high, with only 56% of new products remaining on the market after 5 years and only 8% of new concepts making it to market, with 83% of those failing to meet objectives. All managers must become skilled at analyzing consumer motivation and behavior in order to succeed.
