Gaps Model of Service Quality

A diagnostic framework identifying five gaps that cause service quality failures: the knowledge gap, the policy gap, the delivery gap, the communication gap, and the customer gap between expectations and perceptions.

Service Blueprint

A visual mapping tool that details every step of the service delivery process, distinguishing between frontstage customer-facing actions, backstage support activities, and the line of visibility separating them.

Moment of Truth

Any instance in which a customer comes into contact with any aspect of a service organization and forms an impression of service quality. The term was popularized by Jan Carlzon of Scandinavian Airlines.

Service Recovery

The actions a service provider takes in response to a service failure to restore customer satisfaction. Effective recovery can create higher satisfaction than if no failure had occurred, known as the service recovery paradox.

Customer Expectations Management

The strategic practice of shaping, communicating, and aligning what customers anticipate they will receive from a service, encompassing desired service levels, adequate service levels, and the zone of tolerance between them.

A framework linking internal service quality and employee satisfaction to customer satisfaction, customer loyalty, and ultimately to revenue growth and profitability. Proposed by Heskett, Sasser, and Schlesinger at Harvard.
