The main objective of this research is to examine the relationship between the internal and external service quality dimensions in Egyptian commercial banks. To achieve this objective, the thesis introduced the internal–external service quality model which proposes that the internal service quality has a positive impact on the external service quality. The research model was developed and tested empirically through three main stages. The first stage was based on the extensive review of the literature in order to identity the concepts and measures of the internal and external service quality. In this stage, the research objectives were identified. The second stage was concerned with the building of the internal–external service quality model which proposed that the internal service quality dimensions have a significant positive impact on external service quality. To identify causal indicators for this relationship, some control variables were used and a set of empirically testable hypotheses were developed. [Continues.]
