Customer satisfaction is generally assumed to be a significant determinant of repeat sales, positive word-of-mouth, and customer loyalty. Therefore most companies in telecommunication industry have tried to satisfy customers with high quality at low price in Korea. Even though these efforts have been tried by companies, customers are not satisfied with discrepancy between their expectation and perceived quality. Moreover, the expectation has dynamic and variable characteristics in results from various effects such n technical progress, improved quality and promotions by companies, word-of-mouth, and so on, Therefore, there are not political leverages in assessing the quality and surveying customer satisfaction index in a point of time. As an initial attempt to tackle the questions listed above, this paper puts an effort to make a dynamic customer satisfaction model to understand customer satisfaction in variable situations by introducing 'systems thinking'.

We analyze how much employees' work abilities and overall satisfaction on the job or corporate influence on the productivity and customer satisfaction in the service industry, which is characterized by simultaneity, heterogeneity, intangibility and etc. Employees always encounter customers in process of the service. So, the employees' attitudes and behaviors have direct influences on the service quality or satisfaction which customers perceive. Also, employees' satisfaction or work abilities can lead to increase or decrease the productivity. To grasp and demonstrate the cause and effect relationship, we firstly measure the degrees of employee satisfaction organized by 11 factors through survey, and also measure employees' overall satisfaction, organizational commitment and productivity. Secondly, we define service value as the employee's objective measure index and collect it with the data related to customer satisfaction. Based on the collected data, thirdly we define how the relationship among the employee satisfaction, the productivity, the service value and the customer satisfaction are affected by the employees' work abilities and overall satisfaction with SEM(Structural Equation Model). And finally, we classify employees according to their abilities and the degrees of satisfaction respectively and suggest important strategies to manage them effectively.

Recently, companies are trying to gain a competitive advantage in the market to meet the voice of customer. For this purpose, QFD has been used as product development technology in many areas to include the customer' requirements. Also, Kano model has been used to understand the customer' requirements for an effective way. Therefore integration of Kano model and QFD can more efficiently reflect the customer' requirements when designing a new service. This paper proposes PI index by taking into account the current satisfaction position of our company and competitors while IR (Improvement Ratio) value was set uniformity. This study suggests a more accurate index to predict potential improvements and calculates the final importance or priority. Through case studies targeted at elevator maintenance companies, we can have a general idea how much to improve in the near future and estimate the final importance of customer requirements.

One of the important components of this administrative reform is customer satisfaction. Every public enterprises introduced the Service Charter and Korean government took Customer satisfaction as the key index of public sector performance assessment. Most public enterprises introduced customer satisfaction management in an attempt to improve the quality of customer service. The government granted high incentives to excellent business innovative enterprises and developed additional indices, which are related to CS. From now on, every Korean enterprises must embody feasible customer satisfaction management and improve the quality of customer service In this research, we proposed a quality evaluation standard model which is suitable for the public enterprise based on the Service Quality Criteria, and examined the model. A 7-Point Likert Scale was used based on the five categories within the Service Quality: responsiveness, convenience, tangibility, sympathy and reliability, we analysed the validity and causal relationship among the factors within the model.

Internet Service Quality has been constantly the center of attention to Internet Service Providers. The KII project plan (Korea Information Infrastructure) aims to build broadband backbone networks mainly through optical fiber cables and ATM switches and to Provide the government ministries, local authorities and non-profit organizations with high-speed, highly capable broadband access to these networks at reasonable rates. The KB service model, however, is different from other Internet Service models much in the same way SP (Service Provider) and NP (Network Provider) differ from each other. In this paper, we evaluate KII service according to various customer satisfaction indicators under the methodologies and categories as put forth in both the ACSI (American Customer Satisfaction Index) and SEM (Structural Equation Model). We use a structural equation model (SEM) to demarcate the Korea Information Infrastructure Customer Satisfaction Index (KIICSI) in relation to network service quality. The results of our study suggest some strategies for the KII Project need to be modified and effectively implemented in order to increase the satisfaction level of the KII customers.

This study is aimed at analyzing the characteristics of each service quality and the requirements of the customers followed by the classification of service quality factors of youth sports clubs by using Kano model. For this purpose, a survey was conducted by targeting on 257 subjects in 10 youth sports clubs in Seoul and Gyeonggi areas and for data processing, Microsoft Office Excel 2016 and SPSS 22.0 were used to carry out Frequency Analysis, Factor Analysis, Reliability Analysis, Kano model Quality Classification, Timko's Customer Satisfaction Coefficient, and the computation and analysis of Public-service Customer Satisfaction Index. The following shows the research findings. First, as a result of using Kano model to classify each item of the service quality factors of the youth sports club through Dualistic Quality Theory Attribution, one-dimensional quality elements resulted in all 22 items of service quality factors of youth sports club. Second, the customer satisfaction coefficient computation result showed that satisfaction coefficient appeared by the order of 'kind response of the instructor,'(0.81), 'attitude of the instructor'(0.80), 'systematic lecture program'(0.76), and 'variety of program)'(0.76) and dissatisfaction coefficient appeared by the order of 'clean and pleasant facility'(-0.79), 'attitude of the instructor'(-0.76), 'kind response of the instructor'(-0.76), 'convenience of parking facility'(-0.73), and 'promptness of business process'(-0.73).

This paper is an exploratory study to improve customer satisfaction survey for resolving practical problems. It is natural phenomenon that, as the level of customer satisfaction index increases, the ratio of satisfied customers increases too. However, the effectiveness of practical application of customer satisfaction survey for improvement of customer satisfaction decreases due to its structural limitation on its data analysis system. In order to cope with these problems, we compares the three satisfied customer reclassification methods such as attribute complex scores, satisfaction/dissatisfaction dimension and latent class analysis models. The case study results show that satisfied customer reclassification methods have merits and demerits and are expected to play the role as the groundwork for the revitalization of customer satisfaction survey as well as improving customer satisfaction management.

The purpose of this study was to design a PCSI model that can be applicable to measurement of library user satisfactions, which can be used in evaluating organizational performance. The National Assembly Library (NAL) was selected as a case to design a PCSI-based model and to test the model by conducting a self-administered survey of 341 internal and external library users. The model was validated to have a satisfactory model fit. Fitting the model, the study confirms that the service qualities of the NAL affect user satisfactions, which in turn affects organizational performances. The PCSI score of the library was 80.4, which can be used as a useful index that can compare the library's performance with other organizations in the similar public domain. Major contributions of this study are two-fold: the PCSI-based model proposed in this study provides a theoretical basis that assesses organizational performance of libraries via user satisfaction; and libraries can utilize the model as a management tool to assess the organizational performance from the user perspective.

This study analyzed what premium features significantly affect customer satisfaction and their recommendation, and what factors significantly affect product attributes. In the process, first, the loyalty program and the customer compensation program were studied to determine the impact of the customer satisfaction and recommendation. The study analyzed that quality and design of product properties had significant effects on all factors, but the brand was not significantly affected. Second, while superiority, differentiation and scarcity of luxury items are significant to customer satisfaction but superiority is only significant in relation to recommendation intention. Third, the preceding study shows that the customer compensation program has a significant impact on sales growth, but the study found that it was not for imported luxury car customers. Fourth, if the royalties program is low in awareness, it has been analyzed that the scarcity and customer satisfaction relationships among luxury goods have been adjusted. On the contrary, if there is a high level of awareness, it is analyzed that there is a control effect customer satisfaction and differentiation among luxury brands. In the conclusion, in order to satisfy customers at the import luxury car market, the differentiation of luxury goods by standard index must be strengthened and the brand must be strengthened among the attributes of the product. In addition, by raising awareness of the royalties program, the relationship between differentiation and customer satisfaction can be enhanced.
