HoQ (House of Quality) provides an effective tool not only to arrange and evaluate VoC (Voice of Customers) and VoE (Voice of Engineers), but also to link and combine VoC and VoE, thereby presenting explicit directions for quality improvement. There have been, however, few researches on the HoQ framework in the IT industry. The case study discussed here serves an illustration of the applicability and usefulness of the HoQ approach to website quality improvement. The proposed HoQ framework shows great potentials since customers needs are explicitly considered in the framework, and it helps website administrators develop better web services by providing guidelines for reengineering the website operations.

Properly designed and well-executed services enable e-commerce companies to capture the unique needs and preferences of customers, help them build customer loyalty, and thereby, strengthen their competitiveness in the marketplace. An object of this study is the new open-market company and it has only 3 percent of the market share. Therefore, it is needed to raise the market share by improving the service qualities. This article presents a six sigma project for service quality improvement in the open-market company. This study was carried out based on five steps of DMAIC which is six sigma technique. First, a defect rate was defined as unsatisfaction rate. In addition, 50-people data was analyzed and it was shown that the defect level was 2.5 sigma level. In this study, in order to raise the sigma level, novel eight action items were determined based on SIPOC, FDPM, cause and effect diagram, matrix chart, Pareto chart and statistical analysis.

The complexity arises in defining the construction quality due to its perception, based on inherent market conditions and their requirements, the diversified stakeholders itself and their desired output. A quantitative survey based approach was adopted in this constructive study. A questionnaire based survey was conducted, for the assessment of construction quality perception and expectations in the context of quality improvement technique. The survey feedback of professionals, from the leading construction organizations/companies of Pakistan were analyzed. The financial capacity, organizational structure, and construction experience of the construction firms formed basis for their selection. After statistical analysis of survey feedback it was found reliable and valid for the inferential purpose to the target population of construction professionals. The quality perception was found to be project scope oriented, considered as an excess cost for a construction project and keeping the rework minimum by qualifying the required quality tests, keeping the defects minimum by ensuring the specifications of supplied material. Any quality improvement technique was expected to address the financial aspects of the construction project for the employer and contractor, by increasing the profitability through reduction in overall cost, reduction in time, reduction in defects and improving the productivity in a construction project. The study is beneficial for the construction professionals to assess the prevailing construction quality perception and the expectations from implementation of any quality improvement technique in construction projects.

Personnel engaged in the medical field have implemented continual improvement by team activities in an effort to construct a system that reduces the risks involved in medical care. Knowledge in total quality management (TQM), especially statistical quality control (SQC) developed for industry, seems to be applicable to medical care. This paper describes the application of SQC to continual improvement in medical care.

최근 국내 건설 산업은 높은 경제성장률과 신기술 도입 등으로 인하여 대형화, 초고층화, 첨단화가 되어가고 있으며, 건설 품질에 대한 사용자의 관심과 요구 수준은 더욱 높아지고 있다. 이는 과거의 양적인 성장위주에서 벗어나 시장변화에 능동적으로 대처할 수 있는 한층 더 체계적이고 수준 높은 품질관리의 필요성이 요구된다고 할 수 있다. 정부는 이러한 시대적 요구사항을 반영하여 건설공사의 시공 및 사용재료에 대한 적정성 여부와 부실시공 방지 등 품질확보를 위한 점검을 강화하고 있다. 그러나 이와 같은 점검 강화에도 불구하고 품질관리에 대한 인식 부족 및 형식적인 품질관리 운영 등으로 인하여 많은 문제점이 발생되고 있으며, 품질관리 점검 시 반복적이고 지속적으로 지적사항이 발생되고 있다. 따라서 본 연구에서는 반복적인 지적사항을 줄이고, 부적절한 품질관리와 부실시공을 방지하기 위해 서울시 품질시험소에서 2012년 3월부터 2014년 10월까지 393개 건설현장의 품질관리 적정성 확인 점검을 통해 도출한 지적사항 3,443건을 심층 분석하여 실효성 있는 현장 품질관리 개선방안을 제시하고자 한다. 본 연구에서 제안한 현장 품질관리의 개선방안을 통해 부적절한 품질관리와 부실시공의 방지, 반복적이고 지속적으로 나타나는 지적사항의 감소, 현장의 품질관리 업무향상과 같은 개선효과가 있을 것으로 기대된다.

소재 산업은 공정 기술을 활용하여 최종 제품에 적용되는 부품을 생산하며 완성품의 품질을 결정하는 중요한 기반 산업이다. 그러나 최근 시장 환경이 악화되고 3D 업종으로 인식되어 다른 소재 산업 국가에 비해 경쟁력을 잃어가고 있는 실정이다. 본 연구는 단조 기업의 특성을 분석하고 품질 비용 범위를 설정하여 해당 산업에 특화된 품질 비용 관리 체계 및 지속적 품질 개선 방안에 대한 프로세스를 개발한다. 본 연구를 통해서 단조 산업의 세 가지 특성인 설비 의존, 수주 위주, 현장 중심을 발견하고 내부 실패 비용과 외부 실패 비용을 품질 비용 범위로 설정하였다. 대형 단조업체인 A기업에 대해서 개발된 품질 비용 관리 체계와 지속적 품질 개선 프로세스를 적용하여 총 8개의 품질 과제를 발굴하였으며, 개선 활동 결과 전년 대비 약 63.3%의 품질비용 저감을 확인하여 그 실효성을 증명하였다. 본 연구는 단조 기업들이 체계적으로 품질 비용을 관리하고 분석하여 품질 경영전략 방향성을 수립할 수 있도록 도움을 줄 것으로 판단된다.

Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.

Purpose: This research aims at quality improvement of website services on the internet. Methods: SERVQUAL is redefined for web environments as sixteen statements in five dimensions to identify user requirements for websites and measure their importance ratings. Quality Function Deployment (QFD) is used to integrate user requirements into service development for websites so that management and design guidelines can be obtained for user-oriented websites. Fuzzy set theory is introduced to resolve the ambiguity and subjectivity of user requirements in the House of Quality (HOQ). Results: The priorities of design characteristics are extracted from the Fuzzy QFD for University websites. Conclusion: It is expected to provide quality services in less time with less effort, if the results of the Fuzzy QFD are used to provide services in a strategic way under limited resources.
