Customer satisfaction has long been a fundamental concept in marketing and business strategy. In building a customer satisfaction program, however, the first question that must be answered is, "What does it mean to say that a customer is satisfied?" The simplest and most widely accepted method of defining customer satisfaction is known as expectancy confirmation. Simply stated, if a customer's expectations of a supplier's performance are met or exceeded, the customer will be satisfied. Conversely, if perceived performance is less than what the customer expected, then the customer is dissatisfied. A number of companies have adopted this framework for customer satisfaction and follow a commitment to meet or exceed customer' expectations. In fact, many organizations have gone further by speaking in terms of delighting their customer through performance that exceeds expectations.
