The document discusses the concepts of value and satisfaction. It defines value for customers as the ratio of benefits to price paid, or as the difference between benefits and costs. For marketing, value is the worth customers get from using a product. Benefits can be tangible or intangible, while costs can be monetary, time-related, or psychic. To increase value, companies can increase benefits while increasing or decreasing costs. Satisfaction is a measure of how well a company's products and services meet customer expectations, which are based on past experiences, opinions of others, and information from marketers.
