ABSTRACT
Service quality has strong effects on customer satisfaction, loyalty, retention, and firms' performance superiority. This paper has two aims. The first is to show the differences between customers and employees' evaluations of service quality by implementing an empirical investigation in one of Iranian leading Banks. The second aim is to criticize the existing service quality measurement models in terms of two important difficulties with these methods 1)Simple Additive Relationships between service quality dimensions and 2)Under Achievement Constraint. This paper suggests General Criterion Methodology as a more effective and interactive methodology in order to remove the weaknesses of the existing measurement.
