Service quality has been the subject of considerable interest by both practioners and researchers in recent years (Parasuraman et al 1985). An important reason for the interest in service quality by practitioners results from the belief that this has a beneficial effect on bottom-line performance for the firm. The purpose of this paper is to provide a review of the SERVQUAL research on service quality in the following areas: (1) definition and measurement of service quality, and (2) reliability and validity of SERVQUAL measures.
