The purpose of this study was to empirically examine the customer oriented quality creation by considering quality elements required by customers in the product design process. The study tried to extract attractive quality elements by using Kano's model. After identifying the elements HOQ(the house of quality) of QFD(quality function deployment) was used to identify the trend of quality elements evaluation. Test for equal means (t-test) was applied to verify the attractive quality elements of adult shoes. It made us find the customer oriented quality elements from the customer needs and latent dissatisfaction. We collected the opinions of experts on shoes and complete the cause and effect diagram and affinity diagram (KJ method). The data of the questionnaire was put to the QFD and the contents of quality elements was identified by brain storming method. We calculated indexes which were the multiplication of weight and marks of quality elements in the cross table of the HOQ by QFD. Then we tested for the equality of means between the indexes and the sum of attractive quality elements. The results for equal means were statistically significant. To create the customer quality the product design should be differentiated between the age groups over attractive quality elements.

QFD(Quality Function Deployment) is a very important tool to improve market share by reducing the gap between the voice of customer and the product's performance. But QFD is not a problem solving tool, although it is very useful in identifying what has to be solved or improved in order to meet the customer's desires. TRIZ has proved to be a very strong tool to solve the difficult problems that requires inventive thinking. QFD integrated with TRIZ becomes hot research recently. But merely linking between HOQ(House of Quality) in QFD and the contradiction matrix in TRIZ can not provide designers with a concrete method to solve the technical problem in the design process. Practically, the contradiction matrix and 40 inventive principles are not helpful for solving the technical problem. To solve the technical problem using TRIZ, a search for the tool and the object involved in the problem is made, from which the wanted result should be derived. A practical method to integrate QFD and TRIZ is proposed in this paper.

본 논문은 QFD(Quality Function Development)기법을 활용하여 소비자의 요구사항을 반영한 음식물 처리기의 핵심 품질 요소를 도출하는데 목적을 두었다. 일반 소비자와 관련업계 종사자를 대상으로 설문조사와 FGI를 실시하여 VOC(voice of customer)를 도출하였고, 전문가 그룹을 통해 EC를 도출하여 VOC와 EC(Engineering Characteristic)간의 상관관계를 도표화 하여 HOQ(House Of Quality)를 작성하였다. HOQ 차트를 통해 분쇄건조식 음식물 처리기에 있어 우선시 되는 것은 음식물 분쇄기능, 건조기능 외에 냄새 배출기능, 외관 색상 등의 요소가 중요한 품질요인이라는 결과을 도출하였다. 부품별 요인으로는 분쇄 탈수와 관련 된 모터와 냄새 제거와 관련한 팬모터가 가장 핵심 부품으로 고려되어야 한다는 결과를 도출하였다.

Recently the market of the food waste disposer has increased. Therefore, many companies in the development of food garbage disposer has been increasing interest. In this study, we used QFD (Quality Function Development) to find out the quality factors for the development of the food waste disposer reflecting the consumer needs. HOQ (House Of Quality) showing the correlation between consumer characteristic and engineering characteristic was written by investigating the consumer needs based on the consumer complaints and survey. In addition, we generated the CTQ (Critical To Quality) reflecting the weighting of the importance of the parts. As the research result, the important quality factors for the food garbage disposer were the grinding capability, drying, and odor emission features. The crushing motor associated with grinding and dehydration appeared as the most important quality factors among the parts. Second thing was the fan motor associated with odor. The findings will be able to contribute to the development of the food waste disposer reflecting the consumer needs.

컨테이너항만은 산업구조와 차별화된 고객의 요구에 따라서 점점 변화하고 있다. 이에 따라서 항만이 경쟁력을 가지기 위해서는 서비스 차별화 전략이 필요하다고 본다. 고객들의 요구사항을 객관적으로 평가하기 위하여 품질기능전개(QFD)를 사용하였으며 컨테이너항만의 서비스 프로세스와 서비스품질 척도를 연계하여 분석하였다. 본 연구에서는 부산항의 서비스 프로세스를 분석하고 동북아의 대표항만인 상해항과 도쿄항의 서비스품질성과를 비교하였다. 또한 서비스 품질 향상을 위하여 컨테이너항만의 서비스 품질 척도와 프로세스간의 관계를 나타내고 서비스 프로세스의 중요도 및 우선순위를 도출하여 품질의 집(HOQ)을 최종적으로 제시하였다.

Obtaining the accurate final importance of each customer attribute (CA) is very important in the house of quality(HOQ), because it is deployed to the quality of the final product or service through the quality function deployment(QFD). The final importance is often calculated by the multiplication of the relative importance rate and the competitive priority rate. Traditionally, the sample mean is used for estimating two rates but the dispersion is ignored. This paper proposes a new approach that incorporates statistical significance to consider the dispersion of rates in determining the final importance of CA. The approach is illustrated with a design of car door for each case of crisp and fuzzy numbers.

The research and development stage can improve the goal level of the project through systematic operation and management of systems engineering. The test evaluation tasks in the R&D process have a lot of connections with the system engineering in terms of requirement management, and the methodology for deriving the requirements when establishing the test evaluation items has been consistently required. In this paper, we propose the process of effectively establishing and using QFD (Quality Function Deployment), a tool to manage customer requirement, and drawing up HOQ (House of Quality) in the search and exploratory development stage of the self - propelled mortar project.

Although consumer needs for better products force manufactures to put emphasis on design, often development of a product has been done without the formal process to consider consumer needs. In order to identify the implicit needs of customers and the areas of potential demand on a product, several analysis scheme such as QFD (Quality Function Deployment) has been developed. QFD, also known as the House of Quality, is the efficient tool ever created to tie product and service design decisions directly to customer wants and needs, i.e. VoC (Voice of Customer) To utilize this tool on a product design, first of all, the consumers attributes and the engineering characteristics must be exactly investigated. However there were only few studies about them on shoe design. Hence in this paper we developed an innovative framework for shoes design based on QFD. As a result, we uncovered 29 dominant human satisfaction dimensions as the consumers attributes for customer-oriented quality evaluation of a comfortable shoes. Here, 29 human satisfaction dimensions for a shoe design were identified as the dimensions that represent the human sensitivity and psychological feeling on comfortable shoes. Also, we proposed 60 human interface elements as the engineering characteristics. The relationships between human satisfaction dimensions and human interface elements were investigated. This study will help the designers and manufacturers clarify the conceptual and abstract aspect of the design evaluation by proposing a more systematic and process-oriented method.
