Various studies have been undertaken in order to effectively understand customer requirements. Kano proposed a dualistic approach, physical fulfillment and customer satisfaction, to differentiate Attractive, Must-be, One-dimensional quality attributes. As there were a few limitations on the Kano's method, researchers have proposed improved methods. However, there have been few empirical evidences that the improved methods are superior to the original Kano's method for identifying relevant quality attributes. The objective of this study is to provide a comparative study on Kano and improved Kanomethods based on empirical analysis of quality attributes on University services. For the analysis of the questionnaire formats, the Kano's original 5 scale questionnaire is more effective than improved methods, direct and 3 scale questionnaire. For the analysis of evaluation methods, the original Kano and Timko's method using the evaluation table are more effective than quantifying methods, Domouchel and Lim's methods.

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 requirements which influence customer satisfaction in different ways when met. 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.

Purpose: This study is aimed to introduce the OPA-Kano method, an integrated version of OPA(Originality Practicality Analysis) and Kano's customer satisfaction method, and to examine its applicability. Methods: 30 ideas for smart phone accessories are generated using brainstorming and SIT(Systematic Inventive Thinking) and they are analyzed through the OPA-Kano method. For analysis, correlation method between OPA and Kano's results is applied for the ideas. Results: The results show that there is significant correlation between the OPA and Kano's approach, and the effectiveness of the proposed method is verified through the case of smart phone accessories. Conclusion: From the result of this study, we conclude that the proposed OPA-Kano method can be used for the evaluation of ideas and customer satisfaction.

From fast service enlargement of the latest economy and industry, importance of service industry is embossed gradually. Service enterprise is pushing on in service quality elevation for strengthening competitiveness to survive on globalization society as manufacturing industry. Service quality elevation adapts as core competitive strategy in enterprise with business environment as continuous competitive advantage. Because Public organization also is developed in service fast, Public organization is trying to offer various service such as service level of enterprise. Each Public organization are trying to satisfy request of citizens as Customer. In this study, presented Kano-Servqual Method which is mixed by Kano's and Servqual model's advantage, each Method had used much in service quality measurement separately. Kano-Servqual Method is applied to the A information library as a public organization and is proved as practical useful method.

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.

It is well known that the Kano model measures customer satisfaction and classifies quality attributes into must-be, attractive as well as one-dimensional. The main purpose of this study is to investigate the dynamics of e-learning quality attributes by applying the proposed method using Kano's satisfaction index in the rapidly changing online learning environment. For this, the current study examined 27 e-learning quality attributes and conducted a comparative study using Kano's results obtained in 2013 and 2020. The result shows that the dynamics of quality attributes suggested by Kano(2001) is confirmed in the case of e-learning. The proposed approach shows better results in terms of Kano's direct classification method, and has potential application areas such as IPA(Importance-Performance Analysis) in the area of risk assemement. Some suggestions for better understanding of the proposed SI-DI diagram are also included in this study.

In this paper, we propose development of new products including the proposed process of at the customer's requirements. The success of new product development depends on customer satisfaction in the marketplace. Existing product development process, including the customer's interest was weak. In this paper, we propose development of new products which include Kano's attractive quality factor method and Timko's customer satisfaction index method. Also we verified new medical treatment of incontinence-nency which is applied to the proposed process.

Many Papers of Customer Satisfaction are issued. Kano who have proposed 'Quality Dualism' for grasping of Customers' potential needs and Timko who have proposed 'Customer Satisfaction Coefficient' that made up for the weak points of Kano's model. The Measure of Timko which have weak points as well that does not consider the indifferent quality of the Kano's model. In this paper, we propose 'Total Customer Satisfaction Coefficient' that made up for the weak points of Timko's Customer Satisfaction Coefficient also Kano's Quality Dualism. And we have applied suggested method to department store.
