The document discusses customer expectations of service delivery. It defines customer expectations as beliefs about the level of service they hope to receive (desired service) and the minimum level they will accept (adequate service). The zone of tolerance is the range of service between these levels that customers are willing to accept. Factors that influence desired service are more stable and individual, while factors affecting adequate service are more temporary and situational. These include personal needs, service intensifiers, perceived alternatives, and predicted service levels. Managing customer expectations involves communicating reasons for gaps in service and efforts to improve, as exceeding expectations regularly may unintentionally raise standards over time.
