The document discusses customer expectations of service and how to manage those expectations. There are three main types of customer expectations - minimum tolerable, acceptable, and desired/ideal. Acceptable expectations represent an adequate level of service while desired expectations are the customer's wishes. Customer expectations are influenced by personal needs, alternatives, past experiences, and situational factors. A company must understand customer expectations and the "zone of tolerance" around acceptable service levels to consistently meet and hopefully exceed expectations through reliable service and customer relationship management. Exceeding expectations can create loyal customers but also raises expectations over time.
