The document discusses the gaps model of service quality. It introduces the conceptual framework of the gaps model, which identifies four key gaps in how companies deliver service quality to customers. The first is the customer gap, which is the difference between customer expectations and perceptions. The other three are provider gaps that occur within companies and contribute to the customer gap. These include the listening gap of not knowing customer expectations, the service design gap of not having the right standards, the service performance gap of not meeting standards, and the communication gap of not matching promises to performance. The document provides details on each gap and how analyzing these gaps can help companies improve service quality.
