This document discusses service quality evaluation methods and their usage in the service industry in Poland. It examines how different methods are used and their significance. A survey of 230 service enterprises found that while perceived quality measurement by customers is most widely used, organizational processes measurement has the strongest correlation with key performance factors. However, the utilization of service quality evaluation methods is still insufficient. The document concludes that combining different evaluation methods from the customer, standards, and organizational perspectives into a clear model could help address this issue.
