This document discusses different aspects of consumer behavior related to services. It describes three types of quality attributes - search, experience, and credence qualities - that determine how easily a product or service attribute can be evaluated. It also discusses factors that influence customer expectations, including desired service levels, adequate service levels, and the zone of tolerance between the two. Customer perceptions of service quality are shaped by factors like outcome quality, process quality, and physical environment quality. Properly handling service encounters and recovery situations is important to meet or exceed customer expectations.
