This document discusses models for assessing service quality and service recovery. It introduces the service quality gap model, which identifies five gaps between customer expectations and perceptions that can lead to quality issues. It also presents the service recovery framework, which outlines three phases - pre-recovery, immediate recovery, and follow-up - that companies should follow when service failures occur to minimize negative impacts and regain customer loyalty. Key dimensions of service quality are also defined, such as reliability, responsiveness, and empathy.
