활용 중심의 기록관리 환경에서 효율적인 기록정보서비스를 제공하는 것은 매우 중요해졌으며 더 나아가 제공하는 서비스의 품질에 대한 중요성도 증가하였다. 본 연구는 품질관리기법인 품질기능전개(QFD)를 국가기록원 기록정보서비스에 적용하여 그 개선방안을 제안하기 위한 사전 연구로, 국가기록원에서 제공하고 있는 기록정보서비스의 품질 차원을 분석, 구체적인 이용자 요구사항 항목을 도출하였다. 이를 통해 국가기록원 기록정보서비스 특성이 반영된 이용자 요구사항 설문지를 개발하였으며, QFD를 적용한 선행연구를 토대로 QFD 적용모형을 설계하였다. 본 연구에서 제안한 QFD 적용모형을 기반으로 QFD를 단계적으로 수행함에 따라 도출되는 결과는 HoQ로 표현될 수 있으며 이는 서비스 설계 시 기초자료로 활용할 수 있다.

Obtaining and fully understanding the true requirements of customers is hard task. However, successful use of quality function deployment(QFD) depends on capturing customers' requirements and reflecting them during the design of a product. One of common mistakes in QFD is to perform analysis using an inconsistent house of quality(HoQ) chart. This article presents a model for prioritizing customer attributes and design characteristics in order to make a product more attractive to customers. The proposed model modifies the analytic hierarchical process(AHP) with simple pairwise comparison. Our exploration using of QFD identifies how practitioners maintain consistency, whist quantifying HoQ speedily from the customer's perspectives. This paper also identifies and justifies an alternative position on QFD that is supported by statistical examples.

이 연구는 입지선정에 있어서 사용자의 의견을 반영하고 객관성 있는 입지를 선정하기 위해 품질기능전개방법을 적용하였다. 먼저 품질기능전개의 개념과 적용단계를 고찰하고 해군 전투실험센터 입지선정에 이를 적용할 수 있는 모형을 설정하였다. 전투실험센터 입지선정에 적용하기 위하여 해군과 국방과학연구소의 실무자에게 설문을 실시하여 의견을 수렴하였으며, 그 결과를 분석하여 입지선정시 기술적인 조건들과 함께 품질기능전개 방법론을 적용하였다. 해군과 국방과학연구소의 의견을 반영하여 품질기능전개의 절차에 따라 분석한 결과 진해가 전투실험센터의 최적 입지로 선정됨을 확인하였다.

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.

Viewed as a more systematic approach of creating high quality products and bringing them into market at a lower cost and in significantly less time, it attracts the attention of quality designers to quality function deployment (QFD) approach. In attempt to reduce the design cycle, the industry has responded with concurrent design effort. In a sense, concurrent engineering refers to the integration of various activities within the broad scope of the product life cycle ［17］. Over the last ten years, much has been written about QFD but little has been available in terms of the underlying guide methodology. The methodology of QFD is quite simple and many will say that they have done it in the past but just have not formalized it into the form that this discipline requires. QFD ties the product, user, value, and manufacturing viewpoints together in a continuous process of defining the product design and manufacturing requirements. The value viewpoint recognizes the cost to obtain certain functionality, and the manufacturing viewpoint addresses conformance to requirements, but in a broader sense, the variability in production. In this paper, the QFD system acquisitions are described, and two heuristic approaches solving for the complex design process, especially the size reduction of design process and precedence-constrained relationship in QFD are proposed, and the empirical example is illustrated.

Purpose: To derive key requirements and key technologies for weapon system acquisition business by using Qualify Function Deployment (QFD), and to reduce business cost by setting the target performance and key expense of weapon system. Methods: We propose a QFD methodology that can induce rational decision-making by translating analyst's subjective opinions into quantitative values when analyzing requirements at the initial stage of weapon system development project. Based on QFD methodology, QFD application model combining house of quality, value engineering, and analogy cost estimating technique is presented. Results: It was possible to analyze the specific requirements necessary for the development of the weapon system, to solve the communication problem of the participants, to set clear development direction and target. Conclusion: By applying the QFD application model at the early stage of the weapon system acquisition project, it is possible to reduce the business cost by establishing clear development direction and goal through the procedural analysis process.

This paper presents a tool called Quality-Cost optimization system (QCOS), which integrates Multi-Objective Genetic Algorithm (MOGA) and Quality Function Deployment (QFD), for tradeoff between quality and cost of the unitized metal curtain-wall unit. A construction owner as the external customer pursues to maximize the quality of the curtain-wall unit. However, the contractor as the internal customer pursues to minimize the cost involved in designing, manufacturing and installing the curtain-wall unit. It is crucial for project manager to find the tradeoff point which satisfies the conflicting interests pursued by the both parties. The system would be beneficial to establish a quality plan satisfying the both parties. Survey questionnaires were administered to the construction owner who has an experience of curtain-wall project, the architects who are the independent assessor, and the contractors who were involved in curtain-wall design and installation. The Customer Requirements (CRs) and their importance weights, the relationship between CRs and Technical Attributes (TAs) consisting of a curtain-wall unit, and the cost ratios of each components consisting curtain-wall unit are obtained from the three groups mentioned previously. The data obtained from the surveys were used as the QFD input to compute the Owner Satisfaction (OS) and Contractor Satisfaction (CS). MOGA is applied to optimize resource allocation under limited budget when multi-objectives, OS and CS, are pursued at the same time. The deterministic multi-objective optimization method using MOGA and QFD is extended to stochastic model to better deal with the uncertainties of QFD input and the variability of QFD output. A case study demonstrates the system and verifies the system conformance.

Purpose: The primary purpose of this study is to integrate text mining and Quality Function Deployment (QFD) to automatically extract valuable information from customer reviews, thereby establishing a QFD frame- work to confirm genuine customer needs for New Product Development (NPD). Methods: Our approach combines text mining and QFD through topic modeling and sentiment analysis on a large data set of 56,873 customer reviews from Zappos.com, spanning five running shoe brands. This process objectively identifies customer requirements, establishes priorities, and assesses competitive strengths. Results: Through the analysis of customer reviews, the study successfully extracts customer requirements and translates customer experience insights and emotions into quantifiable indicators of competitiveness. Conclusion: The findings obtained from this research offer essential design guidance for new product develop- ment endeavors. Importantly, the significance of these results extends beyond the running shoe industry, presenting broad and promising applications across diverse sectors.
