The document discusses key concepts in consumer behavior including factors that influence consumer decision making such as psychology, sociology, anthropology, economics and marketing. It notes that consumer behavior must be studied because customers can no longer be taken for granted given high failure rates of new products. Managing requires understanding consumer motivation and behavior, which varies greatly across cultures preventing standardization of marketing approaches. Unless companies adapt to understand consumers, even the most successful companies can fail by repeating past behaviors without realizing changes in consumer preferences and behaviors over time.
