This document discusses service quality and the SERVQUAL model. It defines service quality as an assessment of how well a delivered service meets a customer's expectations. The SERVQUAL model measures service quality across five dimensions: responsiveness, assurance, tangibles, empathy, and reliability. It also identifies five gaps that can cause poor service quality if not addressed: the knowledge gap, policy gap, delivery gap, communication gap, and customer gap. Closing these gaps is important for improving customer satisfaction and delivering high quality services.
