Abstract

As the service sector is rapidly growing, one of the challenges faced by the service industry is the lack of effe·ctive

methodologies for quality analysis and improvement. In service industries, the service quality serves as both a customer

retention tool and a business differentiator in local and global competition. This paper aims at developing a systematic

framework for service quality analysis and improvement. The proposed framework advantageously integrates quality

function deployment (QFD) and structural equation modeling (SEM). More specifically, the framework utilizes QFD to

collect, organize, and analyze qualitative information. The results of QFD are used as the basis for developing a service

quality improvement strategy. Then, SEM is used in building and analyzing quantitative models to devise a detailed strategy

for the improvement. The proposed framework is demonstrated through a case study on the asymmetric digital subscriber

lines (ADSL) service of a major telecommunication company in Asia. This framework can be utilized for an effective

analysis and improvement ofservice quality not just in the telecommunication industry, but also in any service industry which

collects customer satisfaction and service performance data as part of its daily operation.
