This document discusses the dimensions of service quality as defined by the SERVQUAL model. It was developed by American scholars to measure customer perceptions of service quality compared to their expectations. There are five key dimensions: reliability, responsiveness, assurance, empathy, and tangibles. Reliability refers to dependably providing what was promised. Responsiveness is the willingness to help customers and provide prompt service. Assurance is conveying trust and confidence through demonstrated knowledge. Empathy is giving individual attention to customers. Tangibles refers to the physical appearance of personnel, facilities, and equipment. The document provides examples of how these dimensions apply in assessing service quality.
