Literature Review of the Kano Model : Development Over Time (1984-2016)

This research focuses on developing a psychology-based evaluation procedure for innovative design. The divergent thinking part of the main innovative design procedure which discussed in this paper is the extensive QFD developed by the author Wu. Then, the proposed extensive QFD helps transform the high priority requirements into appropriate technical characteristics. According to the priorities of product characteristics, the prior engineering parameters will be identified to be the key performances to redesign.

For identifying the requirements and achieving the attractive design, we introduce the Kano model to construct the evaluation model. The proposed Kano-based evaluation procedure is mainly used in two stages of the innovative design. The flowchart of proposed innovative design procedure with psychology-based evaluation has also been developed. A case study, exercise equipment design, is adopted to explain and verify feasibility of the proposed approach. Customer satisfaction, the major concern to many leading companies, has gradually become the most important factor during the design process.

For identifying the design improvement ratio, satisfaction ratings have been widely used as the indicator of the performance of services or products in many companies. They noticed that a higher degree of customer loyalty is often resulted from higher customer satisfaction. The purpose of marketing and design strategic is to create a high level of customer satisfaction and loyalty so as to win the sustainable development and competitive advantages.

Therefore, in product design, identifying the key design attribute to gain customer satisfaction is very important. Matzler et al. As customers perceive the higher quality, the higher level their satisfaction increasing and vice versa. Kano developed the model of customer satisfaction which identified the characteristics what impact the attributes of products and services on customer satisfaction.

The two-dimensional model developed by Kano et al. Based on relationships between customer satisfaction and performance of a product or service, Berger et al.

These three different types of qualities are as follows: 1 the must-be or basic quality; 2 one-dimensional or performance quality; 3 the attractive or excitement quality. By using the Kano model, the relationship between performance criteria and customer satisfaction can be well understood so that the key performance of product design will also be identified.

For design decision making, listening to the voice of the customer VOC can gain the relevant information about matters which should be improved to increase customer satisfaction [ 5 ]. Zhang and Von Dran [ 6 ] developed a Web site quality model by applying the Kano quality model to a single type of Web site. They find that users of a Web site distinguish three types of quality factors corresponding to their quality expectations; the quality nature of the factors may change over time and the same factor may have different quality identifications in different domains.

Lai et al. Moreover, ambiguity has also been reduced by highly individualized characteristics of customers. The robust design approach focuses on bringing the mean closer to the desired target and simultaneously reducing quality variation.

Sireli et al. Garibay et al. By applying the extension method, Wu et al. For the purposes of achieving higher customer satisfaction and the effectively optimal design decision-making, this study investigates how to integrate the Kano model and extensive QFD design approach.

In this research, a mainly contribution is that a psychology-based evaluation procedure has been developed based on the Kano model. We proposed explicit and feasible intelligent innovation processes and evaluation method progressively. The feasibility will also be verified through design cases. For systematically analyzing concrete or intangible products, Cai [ 11 ] proposed and developed a powerful tool, matter-element, and extension method. The extension method was derived from the extension theory that involves the matter-element theory and extension mathematics.

Incompatible problem in the real world is the major research subject of extension theory. The applications of extension method have already extended to many field such as engineering, business, economics, sociology, management, and strategy [ 12 , 13 ].

The results of concept design research based on extension theory are described as follows: 1 The extensible expression method of concept design knowledge. In this paper, the extensive QFD developed by Wu et al.

In addition, the Kano-based evaluation method is developed to assist decision-making. Therefore, the direction of product development and market positioning can be determined. CRs should be acquired from market surveys or customer questionnaires. The acquired information can be used to calculate the relative and final importance of CRs and also identify the ECs.

The final importance of ECs will be calculated and the relationship matrix also will be established, simultaneously. Customer requirements-orientation is the main spirit of QFD. The most important creativity thinking process is to convert the functional qualities to the engineering design parameters for the customer requirements-oriented innovation design.

Then, the designer should convert the requirements into appropriate technical measures to meet the needs. The priorities of product characteristics can be determined by translating important technical measures.

The prior engineering parameters and the key requirements for redesign will be identified according to their characteristics. During the two processes, extensibility of matter-element and extension method provide effective assistance to the designer in the translation processes of product design attributes and the establishments of engineering properties.

The application of extension method can provide conceiving new products comprehensively and deeply. Extending tree, the front end rhombus thinking, is a method for matter to outward expansion to offer organizational, structural, and multiorientated thinking. The corresponding matter-elements and event-elements can be used to describe these relationships and interactions.

Relationship-element, a -dimensional matrix, is formed by relationship name , characteristics , and corresponding measured values. Divergence, expansibility, relevance, and implication are the extensible properties of matter-element, event-element, and relationship-element. By interactive application of the extensive properties, the solution will not be limited by standard solutions [ 12 , 14 , 15 ].

The revised sub-matter-elements can be obtained by transforming the matter-element with shortcomings to a better one. Corresponding to the elements of , a sequence of new products will occur. Analysis and understanding the matter from the material, systemic, dynamic, and oppositional properties, the structure of matter can be described comprehensively and the nature of development and change of matters can be revealed deeper.

Thus, the new product possesses the required potential function that will be designed. The concepts will be modified by transformation operation to reduce adverse effects.

Finally, designers will get a variety of new product ideas by using basic transformations of matter-element as the following operations:. Many concept design solutions can be obtained by processing the extensive innovation procedure.

Rhombus thinking has two procedures, first stage is divergent thinking process which performs creative thinking and second stage is convergence stage, which is design evaluation stage. These possible solutions obtained in the divergent thinking stage should be evaluated to determine the optimal solutions.

The convergent part of Rhombus thinking model is the procedure of evaluation for decision making. In this paper, an evaluation method has been developed based on Kano model. The Kano model, developed by Noriaki Kano, is a theory of product development and customer satisfaction. As shown in Figure 1 , Kano model classifies customer preferences into five categories, that is, attractive, one-dimensional, must-be, indifferent, and reverse quality. Attractive quality defined as the attributes of product, not normally expected, provides satisfaction while being achieved fully but does not cause dissatisfaction while not fulfilled.

These attributes, which are classified as one-dimensional quality, result in satisfaction while fulfilled and dissatisfaction while not fulfilled. The attributes, which are taken for granted while fulfilled but result in dissatisfaction while not fulfilled, are categorized as must-be quality. Indifferent quality means that these attributes refer to aspects that are neither good nor bad, and they do not result in either customer satisfaction or customer dissatisfaction.

These attributes for reverse quality refer to a high degree of achievement resulting in dissatisfaction for some customer groups. Quality engineering which focuses on the physical level has prevailed so far. However, the aspect of quality proposed by Kano focuses on psychology. In this research, the proposed Kano-based evaluation procedure was mainly used in two stages of the innovative design. Tan and Pawitra [ 17 ] suggested that the designer should pay more attention to attractive attributes first and then the one-dimensional and finally the must-be attributes.

It is necessary to discover the real and sufficient information about matters which satisfies customers so as to establish the priorities in a proper way based on the sufficient analysis.

How to reprioritize customer requirements in QFD by using Kano model is the important issue in this approach. It is very exciting for designers while the attractive factors are identified. Noriaki Kano was the first person to develop a method to identify user requirement and expectation through a preference classification technique [ 3 ].

Three categories of requirements influence user satisfaction in different ways see [ 2 ] : i Must-be user expects the basic qualities and will be dissatisfied if they are not fulfilled. In the extensive innovation stage, that is, the concepts expansion stage, an evaluation characteristic will be defined in 2 and 3 ; that is, , , refers to , , and , separately.

The corresponding values of evaluation characteristics will be obtained based on the Kano model. Attractive, one-dimensional, and must-be requirements as well as product requirements towards which the customer is indifferent or reverse can be classified by means of a questionnaire. For each product feature a pair of questions is formulated to which the customer can answer in one of five different ways [ 18 ].

The first question concerns the reaction of the customer if the product has that feature functional form of the question and the second concerns his reaction if the product does not have that feature dysfunctional form of the question Tables 1 and 2 [ 16 ].

The questionnaire is evaluated as follows: 1 After having combined the answers to the functional and dysfunctional question in the evaluation table, the results of the individual product criteria are listed in the table of results which shows the overall distribution of the requirement categories. Berger et al. To calculate the Better value, we added the attractive and one-dimensional columns and divided by the total number of attractive, one-dimensional, must-be, and indifferent responses.

Reverse and questionable responses were ignored. For Worse, we added the must-be and one-dimensional columns, divided by the same normalizing factor, and put a minus sign in front of the result to get the number. The positive Better numbers are indicative that customer satisfaction will be increased by providing these attractive and one-dimensional elements and the negative Worse numbers are indicative that customer satisfaction will be decreased if these one-dimensional and must-be elements are not included.

From a slightly different point of view, Better indicates how much customer satisfaction is increased by us providing a feature i. These formulas can be described as follows:. Therefore, designers can identify the qualities whether they will fulfill user satisfaction or prevent the user from dissatisfaction.

According to the extended options proposed by Chaudha et al. Tontini [ 21 ] proposed the adjustment factor which is determined by Kano model and can be used directly in the QFD matrix.

Attractive Quality and Must-be Quality from the Viewpoint of Environmental Lifestyle in Japan

Notice of renewal procedure of Institution authentication service. Through the study on quality theory in the literatures of philosophy, quality control, the study of merchandise and so on, we made clear that there are two aspects of quality such as subjective and objective ones and that it is necessary to investigate the correspondence of these two aspects. Then, for this purpose, we propose that two dimensional recognition should replace one-dimensional one which has been so far prevailing, and that this recognition of the correspondence is utilized for categorizing quality elements of a product into attractive, nust-be, one-dimensional quality ones and so on. Then the practical validity of this theory is examined through the questionnaire survey about the TV set and the table clock to consumers and it is investigated how each quality element of these items is evaluated under the theory. Moreover, an example of new clock planning with applying this theory is discussed in order to show the practical effetiveness of this theory. The Japanese Society for Quality Control. References 4.

The Kano model is a theory for product development and customer satisfaction developed in the s by Professor Noriaki Kano , which classifies customer preferences into five categories. One of the main points of assessment in the Kano model is the threshold attributes. These are basically the features that the product must have in order to meet customer demands. If this attribute is overlooked, the product is simply incomplete. If a new product is not examined using the threshold aspects, it may not be possible to enter the market. This is the first and most important characteristic of the Kano model. Threshold attributes are simple components to a product.

Она почувствовала, как по спине у нее пробежал холодок. Лицо коммандера выражало торжественную серьезность. Видимо, в его действиях было нечто такое, что ей знать не полагалось. Сьюзан опустилась на стул.

 - А как же принцип Бергофского. О принципе Бергофского Сьюзан узнала еще в самом начале своей карьеры. Это был краеугольный камень метода грубой силы. Именно этим принципом вдохновлялся Стратмор, приступая к созданию ТРАНСТЕКСТА.

Все данные, свидетельствующие о том, кто чем владел, должны были исчезнуть навсегда. Поскольку для одновременного подрыва устройств была необходима точнейшая координация действий, все эти изделия были связаны между собой телефонными линиями через Интернет. Двое суток встроенные часы устройств обменивались бесконечными потоками зашифрованной синхронизирующейся информации. АНБ, перехватывая эти информационные импульсы, игнорировало их, считая аномалией сети, безобидной тарабарщиной. Но когда ТРАНСТЕКСТ расшифровал эти потоки информации, аналитики тут же увидели в них синхронизированный через Интернет отсчет времени. Устройства были обнаружены и удалены за целых три часа до намеченного срока взрыва. Сьюзан знала, что без ТРАНСТЕКСТА агентство беспомощно перед современным электронным терроризмом.

Ты никогда не смог бы проникнуть в почту коммандера. - Ты ничего не понимаешь! - кричал Хейл.  - На его компьютере уже стоял жучок! - Он говорил, стараясь, чтобы его слова были слышны между сигналами.  - Этот жучок вмонтировал кто-то другой, и я подозреваю, что по распоряжению директора Фонтейна. Я просто попал на все готовое.

 Этот полицейский… - Клушар рассердился.  - Он уронил меня с мотоцикла, бросил на улице, залитого кровью, как зарезанную свинью. Я еле добрел .

Он смотрел на девушку, понимая, что его поиски подошли к концу. Она вымыла голову и переоделась - быть может, считая, что так легче будет продать кольцо, - но в Нью-Йорк не улетела. Беккер с трудом сдерживал волнение. Его безумная поездка вот-вот закончится.

 Я попросил его не звонить мне, пока он не найдет кольцо. - Почему? - удивилась Сьюзан.  - А если ему нужна помощь.
