Abstract
염색 가공은 소비자의 기호에 맞게 실이나 직물에 화학적 처리를 통하여 촉감, 디자인 등의 감각 특성과 방축성, 발수성, 고기능성 등의 하이터치 기능을 부여하는 기술 집약적 산업이며, 섬유제품의 고부가가치화를 위하여 가장 중요한 분야이다. 고객이 원하는 제품을 산출하기 위해서는 제품속성 중 고객이 인지하는 중요도가 높은 곳에 제품의 속성을 치중하여야만 고객 만족도가 올라갈 것이다. 이에 본 연구에서는 고객의 중요도와 만족도의 차이를 확인하기 위한 방안으로 IPA경영 기법을 사용하였다. 또한 경쟁우위를 확보하기 위해서는 제품 설계에서부터 고객의 요구사항이 반영이 된다면, 고객의 만족도는 올라갈 것이며, 고객 만족은 궁극적으로 기업의 재무성과에 영향을 미친다. 고객의 요구는 정량화 되어 있지 않으며, 대부분의 요구사항은 주관적이다. 이러한 고객의 요구사항을 계량화하여 설계에 반영하기 위하여 사용되는 경영기법은 QFD이다. 본 연구의 목적은 IPA기법을 통하여 상품이나 서비스 속성을 평가하여 염색가공 기업들의 품질과 관련한 각 항목들의 중요도와 만족도에 대한 정보를 활용하여 소비자가 인지하는 중요도는 높으나 만족도가 떨어지는 항목을 찾아내고자 한다. 이를 이용하여 염색가공 업체에서 염색가공 제품의 우수한 기능을 개발하고 설계하기 위해서 필요로 하는 기능적 요구사항들을 확정하기 위해 QFD 방법을 염색가공 제품 특성에 맞게 수정하고 이를 이용하여 기능적 요구사항을 도출하는 것이다. 본 연구는 설문조사를 통하여 고객들이 요구하는 사항을 4가지 항목으로 분류하여 조사하였다. IPA분석과 QFD분석을 통하여 제시된 결과는 다음과 같다. 우선, IPA 분석을 통한 결과로는 4가지의 사분면 중 제1사분면에 관련한 집중되어야 할 항목을 살펴보면 다음과 같다. 종업원 문제 및 불만사항 해결 프로그램이 효과적’, ‘가공공정 설정과정에 납품회사 참여’, ‘작업 현장에 공정실행도표 보유’, ‘매출액 대비 품질을 위한 투자비율이 높음’으로 나타나고 있다. 다른 영역에 비해 적은 노력으로도 큰 효과를 기대할 수 있는 부분으로 중점적으로 관리하고 개선되어야 할 중요영역이다 둘째, 상대적 비중이 가장 높은 항목은 ‘작업 현장에 공정실행도표 보유’로 중요도는 높으나 경쟁사에 비하여 만족수준은 낮아 우선적으로 이 부분의 개선이 요구된다. 두 번째로 상대적 비중이 높은 항목은 ‘매출액 대비 품질을 위한 투자비율이 높음’으로 이 역시 중요도는 높게 나타났으나 경쟁사에 비하여 만족수준이 낮은 것으로 조사되었다. 셋째, 염색가공의 품질요소 중요도와 가중치 평가 모두를 고려했을 때 가장 중요시 되어야 할 품질요소는 ‘프로세스’로 나타났다. 섬유염색 가공을 이용하는 고객들의 요구사항을 충족시키기 위해서 가장 먼저 고려해야 할 품질요소는 ‘프로세스’로 조사되었다. 본 연구의 한계점으로 첫째, 고객과 제품을 제공하는 종사원의 요구사항을 비교하지 못한 점이다. 이 두 집단의 상이한 요구사항들은 고객의 불만족을 해소시키거나, 제품의 품질을 높일 수 있는 또 다른 요소이다. 둘째, 향후 연구에서는 보다 정확하고 다양한 고객의 요구사항을 파악해야 할 필요성이 있다. 이러한 한계에도 본 연구는 IPA접근법과 QFD접근법을 동시에 활용하여 섬유의 염색가공 업체의 제품 품질을 개선시키기 위한 체계적인 틀을 마련했다는 점에서 큰 의의가 있다. |Dyeing processing is a technology-intensive industry required to be both the high touch, e.g. shrink proof, water repellency, and high level functionality, and the sensorial characteristics, e.g., tactile impression and design, through chemical finishing technology on fiber and textile use for catering to consumers’ tastes. The dyeing processing is the most important for high value textile products. For producing a product fitted to customers’ needs, products attributes would be well matched to a high level of importance that customer thought. To do this, IPA (important performance analysis) is used to analyze the difference between customer satisfaction and importance. Incidentally, customer satisfaction would increase, if customer needs is reflected in the product design stage. Reflecting customer needs to product design is a crucial because high level of customer satisfaction leads to high level of firm’s future performance. Thus, QFD (quality function deployment) is used to reflect customer needs to the stage of product's design. The purpose of this study is to find quality items that are located on both high level of customer importance and low level of customer satisfaction by using IPA. After then, QFD is used to extract engineering characteristics from the items to design and develop improved dye products. Survey is performed on both customer attributes (or called by voice of customer) and customer satisfaction with four categories. The results of this study are followings as. First, the items in concentrate phase of IPA matrix are ‘effective program to solve employees’ complaint and problems’, ‘supplier participation in process setting’, ‘using run chart in work in place’ , and ‘high level of investment for quality, compared to sales’. These items are expected to large effect on customer satisfaction with less effort than other phases in IPA matrix and have the first priority to manage. Secondly, among these items, the highest proportion of the importance is the using run chart in work in place. This item is needed to preferentially improve because importance is higher and satisfaction is lower than competitive firms. Second priority for improvement is the high level of investment/sales for quality, with a similar reason to first item. Thirdly, the most important engineering characteristic is a process in terms of considering both engineering characteristics and weighted evaluation in dyeing processing to meet customer requirements. Limitations of this study, first, could not compare to demand of employees who provide product to customers directly. The difference of demand between customers and employees is another element either to solve customers’ dissatisfaction or to improve product quality. Secondly, further researches is required to comprehend more accurate and various customer demands. Even with these limitations, this research has a contribution to make up framework for enhancing product quality in dyeing and finishing Industry by using both IPA and QFD.; Dyeing processing is a technology-intensive industry required to be both the high touch, e.g. shrink proof, water repellency, and high level functionality, and the sensorial characteristics, e.g., tactile impression and design, through chemical finishing technology on fiber and textile use for catering to consumers’ tastes.
