Purpose: The Kano model has been widely accepted as a method for classifying quality attributes for almost three decades since its introduction. However, the wordings of the five alternatives in the Kano's questionnaire has been criticised for unclear and confusable meanings. New wordings of the five alternatives are proposed in this paper. Methods: To evaluate the effectiveness of the proposed wordings, we classify 30 quality attributes of smartphones using the conventional wordings and the proposed wordings respectively. The two classification results are compared with the direct classification results by undergraduate students who learned the Kano model. Results: The classification results using the proposed wordings are much more consistent with the direct classification results than those using the conventional wordings. Conclusion: The proposed wordings are less confusable and easy to understand, and thus it results in more consistent with the direct classification.

Purpose: This paper compares and discusses the influence on the quality classification of Kano's questionnaire which is used for the Kano model(Kano et al., 1984), the 3-point Likert-scale newly proposed by Kano and the 5-point Likert-scale presented in this study. Methods: For the comparison, the current study conducts a survey of 631 television viewers. The classification results of the three methods are then compared with those of direct classification which is adopted as a standard for classification of quality attributes. Results: The agreement rates between the results using conventional Kano's questionnaire and the results using direct classification is higher than the results using 3-point and 5-point Likert-scales. In addition, the attributes grouped as must-be or attractive in the direct classification appear to be classified as one-dimensional attributes in the Likert-scales. Conclusion: In comparison with the convensional Kano's questionnaire, the Likert-scale questions highly tend to classify the quatity attributes as one-dimensional. Although the classification results of the 3-point and 5-point Likert-scales are the same, the 5-point Likert-scale has the advantage to classify quality attributes in more detail.

Customer satisfaction is an ever-growing concern of management throughout the world. To find the way to increase customer satisfaction, we must understand customer requirements. Kano distinguishes between three types of product requirements (must-be, one-dimensional, attractive requirement) which influence customer satisfaction in different ways when met. In this paper, potential customer satisfaction improvement (PCSI) index was developed using Kano model and CS coefficient. Timko has developed customer satisfaction (CS) coefficient based on Kano model. The PCSI index represents how much a service feature can increase the degree of customer satisfaction when the service feature is fully fulfilled. In order to explain the meaning of PCSI index, a case syudy of a Family Restaurant is done. It is also discussed how to use the index strategically.

Timko has developed customer satisfaction(CS) coefficient based on Kano model. The CS coefficient is indicative of how strongly a product feature may influence satisfaction. In this paper, we analyzes the factors that influence College Student's Satisfaction of teaching using Kano Model, Timko's CS-Coefficient.

Importance-Performance Analysis(IPA) is a well-known methodology to find the area for improvement. However, the IPA uses different strategies depending on an attribute falls in either 'Concentrate', 'Keep up', 'Possible overkill', or Low priority' quadrant. Problems can occur when attributes locate near the demarcation lines. To solve this problem of IPA, I suggest a modified importance-satisfaction analysis which integrates the Slack(1994)'s diagonal approach and Kano's ASC(Jang et al., 2012) into Yang(2003)'s Importance-Satisfaction model. For this, I investigated 21 smartphone's quality attributes, which adopted from Song and Park(2012)'s study, and conducted a survey of 280 university students for the results of Kano' model and the importance and satisfaction of the quality attributes. The results show that the proposed model enables the business managers to prioritize the quality attributes for improvement through the interpretation on the continuous diagonal line using the Kano's questionnaire only, without acquiring any additional survey for importance of attributes. Accordingly, it is expected that the newly proposed method will diminish the limitation of the existing IPA. In addition, to test the validity of the ASC, this study conducts a comparative analysis between the Kano's ASC and Tontini(2007)'s method to determine the relative importance of quality attributes.

Kano model offers an effective way to understand customer requirements strategically Thus, the integration of Kano model and QFD can reflect customer requirements more effectively in designing new product. Most of previous studies on the integration have been focused customer attributes, but engineering characteristics are used at the final stage of new product design. It is proposed that how to classify engineering characteristics into Kano's elements and how to use the classified results in new product development process in this thesis. A case example is included to explain the proposed method.

소프트웨어 개발과정에서 사용자 요구사항을 정확히 만족하기 위해서는 사용자 관점에서 요구사항을 검증하기 위한 방법이 필요하다. 이것은 사용자의 요구사항이 시스템 개발자에게 적절히 반영되어 사용자가 요구하는 고품질의 소프트웨어 시스템을 더 효과적으로 설계하고 구현할 수 있기 때문이다. 본 논문에서는 시스템 구현 전 단계에서 사용자 요구사항을 효율적으로 검증할 수 있는 RV-UI 모델 시스템을 제안한다. RV-UI 모델 시스템은 상용화된 사용자 인터페이스를 프로세스별 기능 모델로 표준화하여 구성하였고, Kano의 모델을 적용한 인터페이스를 통해 명화한 사용자 요구사항의 검증과 체계적인 요구사항의 형상관리를 가능하도록 설계 하였다.

Timko has developed customer satisfaction(CS) coefficient based on Kano model. The CS coefficient is indicative of how strongly a product feature may influence satisfaction. As there were a few limitations on the Kano's method and on the Timko's customer satisfaction index method. The objective of this study is to provide improved methodology based on the Kano's method. One case studies are solved by the proposed method.
