Abstract

This paper CTQ(Critical to Quality) to draw, aim to derive a key quality factor reflects the customer's requirements by utilizing the QFD technique for sparkling water purifier device that combines the new module. Tasting participants, consumers and New Module device intended for developers who develop and conduct a survey and FGI (Focus Group Interview) VOC(Voice of Customer) to draw, drawn by the EC through the developer VOC and EC (Engineering Characteristic) and charts the relationship between the phases was prepared HOQ(House of Quality). Sparkling water purifier through the HOQ chart certain taste, sound, running water, CO2 cylinder replacement cycle, we obtain results that element is an important quality factors such as ease of use. These factors are closely related to each component regulators and Module device (mixing) associated with the taste of water, booster pumps, and deliver results that the solenoid is considered the most critical part.

본 논문은 New Module장치를 융합한 탄산수 정수기에 대한 CTQ(Critical to Quality)를 도출, QFD기법을 활용하여 소비자의 요구사항을 반영한 핵심 품질요소를 도출하는데 목적이 있다. 시음 대상자, 일반소비자와 New Module장치를 개발한 개발자를 대상으로 설문조사와 FGI(Focus Group Interview)를 실시하여 VOC(Voice of Customer)를 도출, 개발자를 통해 EC를 도출하여 VOC와 EC(Engineering Characteristic)간의 상간관계를 도표화하여 HOQ(House of Quality)를 작성하였다. HOQ 차트를 통해 탄산수 정수기는 일정한 맛, 소음, 출수량, CO2 실린더 교체주기, 사용 편리성 등의 요소가 중요한 품질요인이라는 결과를 도출 하였다. 부품별 요인으로는 물의 맛과 관련된 Module 장치 (혼합조)와 이와 밀접한 레귤레이터, 부스터펌프, 솔레노이드가 가장 핵심부품으로 고려해야 한다는 결과를 도출 하였다.
