The relationship between service quality and customersatisfaction investigation with the structural equationmodeling of GSM operators

Service quality is a very important concept for companies. The satisfaction level of the customer shows us the service quality of the company. All companies have to improve their quality in order to increase their profits and fix their problems regarding the service in today's tough competitive conditions. That is why the quality of the service can be measurable. The method of SERVQUAL has founded by Mr. Parasuraman and by his friends at the beginnings of 1980's and the aim of this method is measure the quality of the service. This method invite the customer to fill up a survey for checking their feedbacks. The answers of this survey gives us the result of quality about the service. Thanks to SERVQUAL method, we can check the satisfaction level of our customers. Through these studies we can see the loyalty level of our customers to our company and also their trust to us. We will check the satisfaction level of customers and quality of the service for the biggest telecommunication companies in Turkey such as Turkcell, Vodafone and Turk Telekom with using this study SERVQUAL. According to the results, we will be able to compare companies services and also we will see the positive & negative comments. In order to examine this relationship, we have to use one of the dependent method. The discovery of relationships between all variables analyzed simultaneously allowing multiple variables are benefiting from the Structural Equation Modeling. As a result of study suggested the validity of the theoretical model is determined and established six hypotheses and dismissed two of them. Three dimensions on the quality of the serving that significantly effect on satisfaction and loyalty were identified.
