The identified elements of logistic customer service in an organization are placed on a specific level, as assessed from the perspective of the purchasers' expectations. Among various methods for measuring customer service level, or quality, which are described in the literature on the subject, the SERVQUAL is recognized as one of the most effective. The SERVQUAL method relies on measuring the differences that exist between the quality, as perceived by a customer, and the quality demanded by that customer from a specific service. In order to determine the difference, both the customer's expectations for the service level and their fulfillment by a specific organization need to be examined at the same time.
