This paper demonstrates the application of a Quality Function Deployment (QFD) and Zero-One Goal Programming model for selecting interdependent information system project selection, there are a few research for interdependent IS project selection. Effective project evaluation necessities incorporating the many conflicting objectives of decision maker(s) into decision models. Among the many proposed methodologies of multi-criteria decision making (MCDM), Goal Programming (GP) is the most popular and widely used. The model departs from an earlier GP formulation of the problem that suggested QFD method for selection of priorities among the considered attributes or criteria. The application of the proposed methodology illustrated through an example.

Logistics companies want to be competitive companies in fierce logistics market and are worrying about securing of differentiated competitiveness for it. The standards judging if logistics industry maintains the competitiveness are based on the satisfaction of users due to the well-established service system that can response not only economic feasibility of logistics costs such as transportation costs, storage costs, unloading charges, information costs, etc. but also diversity and upgradability of logistics needs. Therefore, this study focuses on seeking of service quality improvements with VBSD(Value Based Service Design) model focusing on customer value factors based on Kano model and QFD based service design approach from angles of customer value improvement and service costs reduction.

In this study, the multi-criteria decision-making model based on Quality Function Deployment Method is proposed. Multicriteria decision-making is an attempt to link QFD method with the TOPSIS. By this effort, a model that makes client's decision-making more rational and objective in design phase is suggested. The multi-criteria decisionmaking model confirming to the Owner's requirements will improve the productivity of the construction industry and the satisfaction of the customer. Further study extending the range of the requirements, not only the Owner's requirement will be necessary to cover the various factors as much as possible. And then, finally as a flexible platform to achieve a sustainable quality management, web-based multi-criteria decision-making model can be utilized by the relevant stakeholders simultaneously with the feed-back and sharing the necessary informations.

Nowadays, new product development (NPD) is one of the most crucial factors for business success. The manufacturing firms cannot afford the resources in the long development cycle and the costly redesigns. Good product planning is crucial to ensure the success of NPD, while the Quality Function deployment (QFD) is an effective tool to help the decision makers to determine appropriate product specifications in the product planning stage. Traditionally, in the QFD, the product specifications are determined by a rather subjective evaluation, which is based on the knowledge and experience of the decision makers. In this paper, the traditional QFD methodology is firstly reviewed. An improved Hybrid Quality Function Deployment (HQFD) [MSOfficel] then presented to tackle the shortcomings of traditional QFD methodologies in determining the engineering characteristics. A structured questionnaire to collect and analyze the customer requirements, a methodology to establish a QFD record base and effective case retrieval, and a model to more objectively determine the target values of engineering characteristics are also described.

This research is for developing a usability evaluation model based on customer sensation using Quality Function Deployment, which evaluates the relationship between consumer sensation and usability among the physical design factors of dishwashers. Four aspects of the evaluation model; overall sensation factors, detail sensation factors, usability evaluation factors and physical design factors of products were analyzed in three sequential processes of QFD. The sensation evaluation factors and the usability evaluation factors were created from regression analysis of the results of the sensation and usability test. Moreover, thirty-one physical design factors selected through group discussion of ergonomist and manufacturers. Among them, 19 physical design factors according to priority were applied to evaluation model using QFD. With the evaluation model using four aspects, physical design factors influencing user sensation were generated. These factors were 'alarm sound', 'dishwasher size', 'button size' and 'display size'. Consequently, the degree of influences was tested. Design guidelines for dishwashers were derived from finally generated physical design factors.

This study aims to apply QFD model to improve and evaluate library service quality using user needs priorities. The library of the D University is presented as a case study. QFD is a powerful quality management method in which customer needs are translated into appropriate technical requirements for each stage of product/service development. To apply QFD in the field of library services, first library user needs and their AHP, satisfaction and importance degrees were examined via focus group interview. Second, the service improvement engineering characteristics for satisfying the user needs and their relationship/correlations matrices were defined by interviewing library practitioners and experts. Finally, the data collected was entered using CUPID solution, and then HOQ to improve library service quality of the D University was constructed. This study focused on QFD method and its application as a tool for improving the quality of library service.

Modern management considers customer satisfaction as a baseline standard of performance and a possible standard of excellence for any business organization including the college. Quality function deployment(QFD) is a structured approach to seek out voice of customers, understanding their needs, and ensure that their needs are met. The strategy value proposed by Chien et al. combines importance, satisfaction, performance, and ability to enhance decision making effectiveness. But in their model, the correlation among the strategic alternatives isn't considered the decision chain and is therefore eliminated. This paper proposes how to calculate the new weight of columns to consider various strength levels of correlations matrix, representing the correlation among the strategic alternatives, using normalization procedure. The aim of this paper is to present and original customer satisfaction survey conducted in the college. Thus, this paper presents an original customer satisfaction survey in the college and provides to demonstrate the practical usage of the design model to compare this model with Chien's model.

SEI(Software Engineering Institute)의 CMM(Capability Maturity Model)은 소프트웨어 개발 공정 및 조직의 성숙도를 5개의 계층적인 단계로 분류, 평가하며, 성숙도 측정의 기준으로 계량적인 메저먼트를 각 단계별로 제시하고 있다. 본 연구에서는 CMM에 의해 제시된 메저먼트에 근거하여 정의되고 사용된 척도의 선정에 정보시스템 개발 및 품질 관리 기법인 QFD(Quality Function Deployment)를 적용하였다. 척도 사용자 그룹으로부터 CMM의 관심 영역, 사용 척도, 척도 계산에 필요한 측정치, 소프트웨어 개발 생명주기에 이르는 과정을 단계적인 흐름으로 파악하여 적절한 척도를 선택하는 데 본 연구의 목적이 있다.

In this paper, the QFD(quality function deployment) technique is used to acquire the quality requirements of package software which is sold in a commercial software shop. To select the principal quality characteristics of package software, an user survey was conducted for a quality model developed based on the international standards and the previous research. The software user is divided into three groups：the general user, the expert, and the developer. The method of QFD is applied to choose the software quality attributes which have strong correlation with the selected quality characteristics.

Recently, companies are trying to gain a competitive advantage in the market to meet the voice of customer. For this purpose, QFD has been used as product development technology in many areas to include the customer' requirements. Also, Kano model has been used to understand the customer' requirements for an effective way. Therefore integration of Kano model and QFD can more efficiently reflect the customer' requirements when designing a new service. This paper proposes PI index by taking into account the current satisfaction position of our company and competitors while IR (Improvement Ratio) value was set uniformity. This study suggests a more accurate index to predict potential improvements and calculates the final importance or priority. Through case studies targeted at elevator maintenance companies, we can have a general idea how much to improve in the near future and estimate the final importance of customer requirements.
