Many firms try to enhance the customer satisfaction, because they believe that higher customer satisfaction leads to superior returns. According to expectancy disconfirmation model, consumers judge the satisfaction in comparison with their expectations about the product performance. If the performance is above the expectations, increase in satisfaction is expected. If the performance is below the expectations, decrease in satisfaction is expected. This explanation contradicts our beliefs that higher expectation leads to consumer's choices. To address the contradiction, this paper present a unified model which combines the expectancy disconfirmation model with the well-known diffusion model. The unified model shows that the expectation can increase the choices even if the expectation decreases the satisfaction.

The delivery of high service quality is an evitable strategy that has been related to a success in discount store industry. Greater competitiveness has caused discount store firms to be increasingly aware of the importance of service quality to be on a competitive edge. Also, the fact that service quality leads to customer satisfaction has driven many researchers and practitioners to focus on the issue. What we suggest is that customer's expectation change of service quality cannot be regarded as two totally unrelated processes. If quality judgments are based on expectations, it is important to understand the origins of those expectation change. Therefore, if being of effecting factors between the latest expectation and the changed expectation of service quality will prove out, service firms are possible to operate efficiency quality management for getting customer satisfaction.

The results show that the expectancy disconfirmation influences significantly to user satisfaction. Expectation and satisfaction levels of commercial DBMS users are higher significantly than those of open source DBMS users.

This study investigates the influence of self-efficacy in purchasing clothes in the consumer satisfaction formation process. A survey was conducted on 300 adults living in the Seoul and Gyeonggi area and 231 completed questionnaires were used for analysis. The survey questionnaires measured the respondent's self-efficacy in purchasing clothes, expectation, perceived performance, expectation confirmation, and satisfaction level. The data were analyzed by moderated regression analysis. The results are as follows. First, for apparel products, perceived performance, and expectation confirmation have a direct effect on consumer satisfaction, while expectation has no direct effect on consumer satisfaction. This finding agrees with the results reported in a previous study on consumer goods with low ambiguity in assessing products and services including sneakers, underwear, cereals, and financial services. Second, the lower the self-efficacy in purchasing clothes, then the increased effect of the expectation confirmation that influences consumer satisfaction. However, the self-efficacy in purchasing clothes did not show any moderating effect on the perceived performance affecting the consumer satisfaction. The self-efficacy in purchasing clothes seems to have a moderating effect on the consumer satisfaction formation process by affecting the ambiguity in pre-purchase product assessment and not in post-purchase product evaluation.

The purpose of this research is to investigate the characteristics of big data-based fashion shopping (BDFS) application, perceived usefulness, and expectation confirmation that influence the continuous usage intention of BDFS application users based on the expectation-confirmation model. A survey was conducted with female consumers in their 20s, who are living in Seoul and Incheon area and have used BDFS applications, A total of 182 responses were used for the data analysis. Five hypotheses were proposed, and regression analyses were conducted to test those hypotheses. The results indicated that the users' perceived usefulness increased with the increase of accuracy and personalization characteristics of the app and the expectation confirmation. The result suggested that it is essential to provide accurate information for users to feel useful and to develop the personalized offerings and services which can be the biggest strength of the big-data based mobile fashion store. It was also found that continuous usage intention increases with increased perceived usefulness and expectation confirmation. This result suggests that expectations can play a critical role in perceiving the usefulness of BDFS applications and the user's expectation confirmation also significantly affected the users' continuous usage intention.
