This paper presents a method which optimizes the cost allocation in the design process of a metal curtain-wall unit using Quality Function Deployment (QFD) method. From the literature survey, it was found that previous researches have been focused on maximizing customer-satisfaction using QFD without considering the constrained budget. This paper describes how the limited budget condition is considered in the QFD process for a curtain wall design. A case study is presented to demonstrate the applicability of the method proposed by the authors. The method contributes to deliver the curtain-wall design in a way to satisfy the level of requirements of both the customer and the curtain-wall contractor by calculating a solution vector allocating limited budget to the Technical Attributes(TAs) of the curtain wall unit according to the importance weight of Customer Attributes(CAs).

This paper presents an analytic method of quality function deployment(QFD) that is to maximize customer satisfaction subject to technical and economic sides in process design.

QFD is a market driven design and development methodology for products and services to meet or exceed customer's needs and expectations, This method enables to specify clearly the customer's needs and then evaluate the product capability in terms of its impact on meeting those needs. Process of satisfying customers begins with effectively soliciting their different needs and wants which may be non-technical and imprecise in nature. Although the HoQ is a comprehensive tool for showing the relationships between attributes, it lacks the flexibility to deal with the inherent inexactness and vagueness in the voice of customer. In this paper, fuzzy theory is introduced to overcome this limitation. Qualitative customer requirements are interpreted quantitative data through fuzzy inference procedure, and then target value is determined.

Today, an effective website design has emerged as a thing of main concern for online shopping businesses and thus the companies involved in the online shopping businesses are aspiring for well-designed websites. In the past, several methods have been reported but they proved unproductive as they failed to handle the decision making involved in the process to evaluate the customer needs efficiently. Thus to cope up with the issue, the paper considers QFD approach as it a customer driven process that strongly assists in guiding the design decisions. The purpose of this paper is to explore the issues that have resulted in the decrease of satisfaction rate of users, analyze the problems with the methods used and propose effective solution through the literature review. The contribution of this paper is manifold. First, it explores QFD at length and evaluates its applicability for effective design of online shopping websites. This helps users understand the decision making capabilities of QFD. Second, it highlights the limitations of QFD approach in handling the vague and imprecise data that arise due to the inherent crisp approach and subjectivity involved in the QFD approach. Finally, the paper proposes fuzzy integration with QFD to deal with the uncertainty and vagueness involved in the QFD process for improved decision making and more precise results leading to effective design of online shopping websites. The literature review is based on information from various research papers, tools and web sources.

본 연구의 목적은 고추장 소스의 제품 개발을 위해 소비자 요구에 기반을 둔 Quality Function Deployment(QFD) 모델을 적용하고자 하였다. QFD는 고객의 요구 사항이 제품이나 서비스 개발의 각 단계에 반영될 수 있도록 하는 강력한 품질 경영 도구이다. 고추장 소스 제품 개발에 QFD 기법을 적용하기 위해 먼저 소비자로부터 요구 사항을 도출하고 소비자의 중요도, 수행도 분석을 위해 소비자 설문조사를 실시하였다. 다음으로 전문가 인터뷰를 통해 기술특성을 도출하고 품질표 및 상관관계를 정의하였다. 최종적으로 각 단계에서 수집되고 해석된 데이터를 이용하여 고추장 소스 제품 개발을 위한 품질의 집을 완성하였다. 그 결과 고객인지도 비교에서는 고추장 소스의 신선한 풍미를 가장 중요하게 생각하였으며, 음식 풍미 향상, 음식 활용도 높음의 순으로 높게 나타났다. 고추장 소스의 품질에 대한 요구도와 개선비를 모두 고려하여 우선순위로 연결해 본 결과 신선한 풍미, 음식 풍미 향상, 음식 활용도 높음, 활용 가능한 레시피 제공 등이 높게 분석되었다. 이를 통해 소비자들은 고추장 소스 제품의 외관적인 측면보다는 풍미와 관련된 제품 품질을 더 중요하게 생각하는 것으로 나타났다. 기술특성의 난이도는 구매용이성, 브랜드 개발, 현지 식재료 사용, 독특한 콘셉트가 높게 나타난 반면, 순한 매운맛, 선명하고 탁한 붉은색, 끈적끈적하게 천천히 흐르는 점도에 대해서는 난이도 점수 및 순위가 낮게 나타났다. 기술특성 값을 중심으로 실행 난이도와 기술특성 간의 상호관계를 고려하여 기술특성 우선순위를 매겨 본 결과 용도 다양화에 대한 속성이 가장 높은 우선순위를 차지하고 있는 것을 알 수 있었다. 다음으로 무료 샘플 및 시식, 독특한 콘셉트, 브랜드 개발, 고추장 소스의 입자 보이지 않음 순으로 우선순위가 높게 나타났다. 이를 통해 고추장 소스의 개발과 이의 소비 확대를 위해서는 현지 소비자가 쉽게 접할 수 있는 레시피 개발과 동반 음식을 함께 제안하는 것이 필요할 것으로 사료된다. 고추장은 매운 맛을 내는 소스 중에서 발효라는 공정을 거쳐 제조되므로 이러한 이미지를 부각시켜 기존의 매운 소스와의 차별성을 둔 현지인 맞춤형 포지셔닝 전략이 필요할 것이다. 한편으로는 제품 콘셉트 도출 단계에서부터 소비자가 직접 참여하는 프로슈머 마케팅을 잘 활용하면 그들의 요구사항을 반영한 맞춤 상품을 공급할 수 있을 것이다. 이는 고객 만족도를 높이는 것뿐만 아니라 브랜드에 대한 로열티를 높일 수 있으므로 고추장 소스 콘셉트 개발 시에도 이러한 방법을 이용한다면 소비자의 니즈를 충족시킬 수 있는 차별화된 제품을 개발할 수 있을 것이라 판단된다. 그러나 본 연구는 편의추출법에 의해 설문 대상자를 선정하였고, 미국의 뉴욕 맨해튼과 중국의 베이징이라는 지역적 제한점을 갖고 있어 미국과 중국 대부분의 소비자 니즈를 반영했다고 보기에는 어려움이 있다. 이에 따라 향후 외적 타당도의 저해 요인들을 감소시킬 수 있는 소비자 계층에 따른 샘플링, 지역적 범위를 확장시킨 조사 설계 연구가 필요할 것으로 사료된다.
