A strategic approach to customer satisfaction in the telecommunication service market

As is the case in most other service industries, customer satisfaction is of paramount importance in the telecommunications industry. owever, customer satisfaction management in the telecommunication industry is difficult because of the diversity of services and customer segments that exist. This diversity makes it implausible to have a uniform customer satisfaction questionnaire that can be administered to all the different service/customer segment combination. Therefore, we first carried out a segmentation study to identify key customer segments for Korea Telecom, and then focused on one service/customer group in developing the questionnaire. The questionnaire was developed using the SERVPERF approach to measuring service satisfaction. We then developed a decision support system to manage and analyze the customer satisfaction data. The system consists of data input, tracking ability, and statistical modeling capabilities. The computer software was designed as an “open” decision support system that was intended to be used by a wide and general audience within Korea Telecom to review and make active use of customer satisfaction data.
