  • New product development is a complex managerial process which involves multiple functional groups, each with a different perspective. Quality function deployment (QFD) is a new product development process which stresses cross-functional integration. QFD provides a specific approach for ensuring quality through each stage of the product development and production process. This paper provides an overview of QFD including its concepts and methods, and then proposes an integrated approach to formulating and solving the QFD process. This paper also discusses issues associated with the prescriptive modeling of QFD.

  • The primary goal of the requirement analysis phase during information system development is to identify and document what is really needed, in a form that clearly communicates to the user and to development team members. Presented in this paper is a QFD(Quality Function Deployment)-based requirement analysis method and procedure for developing a large-scale enterprise information system. For the purpose of elicitation of software functional requirements, this paper adopts the method of HOQ(House Of Quality) and proposes a simplified HOQ which is more suitable for the software requirement analysis. As a result of this paper, it suggests desired functionalities for an integrated design &manufacturing information system.

  • The purpose of this study was to develop a design process for a functional and sensible brassiere for muddle - aged women. As a methodology, an engineering design process QFD (Quality Function Deployment) was adopted to translate the consumer's needs into product design parameters. the customer needs for the wear comfort of brassieres were extracted from a survey of 100 women aged 30 - 40. To select which items were critical and which could be traded off for other attributed or benefits. the importance ratings for the customer needs were determined. Customer needs were translated into technical language by various physical test methods and wear tests. The customer competitive assessment was generated by wear tests of 10 commercial brassieres under controlled environmental conditions of 28${\pm}$1$^{\circ}C$, 65${\pm}$3% RH. The relationship matrix between the customer needs and the means of delivering the needs was developed. Using the QFD methodology, design elements for developing a brassiere for middle-aged women could be analyzed and organized efficiently.

  • A design needs various experience and design knowledge through a whole design process. Despite of all efforts and time, it is not easy to introduce a product that meets all customer's needs and expectation in time. To achieve the product goal, designers need a set of sequential process to find appropriate design parameters and ensure customers' needs and requirements. In this research we propose a design methodology for the initial design of an excavator front group with existing QFD(Quality Function Deployment) and Axiomatic Design to satisfy customer's requirements. It turns out that the proposed methodology can support designers more effectively, objectively, and systematically.

  • The purpose of this study is to develop functional and sensible brassiere for middle-aged women. As a methodology, engineering design process, especially, QFD(Quality Function Deployment) was adopted to translate consumer's needs into product design parameters. Wearing tests of commercial brassiere were performed for the development o subjective measurement scale. The environmental condition was controlled at 28$\pm$1$^{\circ}C$, 65$\pm$3%RH. As results, subjective measurement scale and dimension for the evaluation of sensible brassiere were extracted from factor analysis. Four factors were fitting, aesthetic property, pressure sensation, displacement of brassiere due to movement. Regression equations with the subjective evaluation descriptors were developed for the prediction of wearing comfort of brassiere. (R2=.82) The most critical design parameter was wire-related property and second one was stretchability of main material of brassiere. Also, wearing comfort of brassiere was affected by the interaction of initial stretchability of wing and support of strap.

  • These days mobile phone which were used mainly by grown-up persons are now widely used among children as well due to new social demands. Despite this trend, existing mobile phones are still being designed and produced according to the taste of people in their 20s and 30s, even the elderly, not satisfying physical, emotional and cognitive characteristics raised by children. This study aimed to extract the design factors of mobile phones for children by reflecting functional factors requested by children and parents in QFD's customer demands. First, functional and design factors requested in mobile phones for children were extracted from existing products and documentary records and some functional factors were selected through a process of integration and omission. The survey research was conducted on children and parents, based on the selected functional factors. Based on the survey research, functional factors were analyzed using AHP, and key functional factors considered by children and parents in mobile phones for children were investigated. Finally, in order to reflect the results in QFD, the correlation between functional factors and design factors was constructed as HOQ through experts' evaluation. The results showed that both children and parents recognized the basic functions such as telephoning, text messaging and phone directory as high priority functional factors, even though the relative importance was different between children and parents. Therefore, it is likely to satisfy the desires of both children and parents by designing mobile phones for children in consideration of design factors such as menu depth, button independence and button arrangement. It is expected that this study will promote experiments on design factors and propose basic data for and guidelines to mobile phone design for children.

  • 본 연구는 대기업, 중견기업에서 주로 사용되어온 QFD (Quality Function Deployment)를 창업기업에 접목하여 초기성장기의 창업 기업들의 성장 도태, 매출 정체에 대한 해결 방안으로 QFD 교육 훈련 프로그램에 참여하였던 창업 벤처기업들을 그 연구 대상으로 하였다. QFD 교육 훈련과정에서 임직원들이 배웠던 내용을 현업에 실제로 접목하고자 하였는지 즉 교육 훈련 성과가 있는지에 관하여 연구하는 과정에서 학습전이 의도 영향 요인과 그 경로 구조에 학습자의 개인적 특성이 조절 기능을 하는 지에 대해 실증적으로 규명하고자 하였다. 실증분석의 결과는 학습자준비상태와 훈련내용의 타당성인지가 자기 효능감을 통해 학습전이의도에 영향을 미치는 관계에서 학습자의 인구통계학적 특성의 조절효과는 성별이 부분 조절효과, 직급이 조절효과가 있는 것으로 나타났고, 연령과 학력수준, 창업경력은 통계적으로 유의한 결과가 나타나지 않았다. 본 연구의 시사점은 현실에 접목하기 쉽게 실천중심으로 설계된 훈련 프로그램을 진행할 때 프로그램 결과가 그 기업에 직접적으로 성과를 달성하도록 하기 위해서는 창업기업의 의사결정에 큰 영향력을 미치는 대표이사가 참석하도록 의무화하는 것이 훈련 프로그램의 성과를 높이는데 큰 효과가 있다는 것을 실증적으로 규명한 것이다. 이를 통해 창업기업대상 교육 훈련 프로그램을 진행하는 집행 기관의 교육 기획 단계에서 정책적 시사점을 제공하는 것을 목적으로 하였다.

  • We develop the evaluation method of functional requirements for excavator design. The functional requirement of the product can be deduced from voice of customer. QFD method is used in order to convert customer requirement to functional requirement. The measure of information index is used to evaluate quantitatively the product quality characteristics. The correlation score between customer requirements and functional requirements and benchmarking score of competitors are basic data for the measure of information.

  • This work describes a derivation process of JIC(Joint Integrating Concept) based JFC(Joint Functional Concept) analysis of an Aegis BMD(Ballistic Missile Defense). JIC is developed through JOC(Joint Operating Concept) and JFC based on capstone strategy and concept. Aegis BMD is a sea-based ballistic missile defense to detect ballistic missile threat, increase engagement battlespace and enable multiple engagement based on Aegis ships. Aegis BMD is a good case of JIC due to performing an Joint operations based on System of Systems under highly complicated NCW environment. This work analyses JFC using QFD(Quality Function Deployment) and UJTL(Universal Joint Task List). From this analysis the JIC of Aegis Korean BMD is derived using a CASE tool.
