참여자 의사결정 성향을 고려한 요구성능 기반의 QFD 평가방법 및 설계변경 프로세스

It is a essential element of decision-making problem on design quality management and change process. Domestic design quality management has a major problem such as Methods/Materials/Systems selection error, insufficient design features caused by inadequate design review, and qualitative decision making process. It is due to lacks of comprehensive review of method in design solutions, insufficient of understanding of stakeholder requirements, and rely on technicians' empirical experience. Therefore, this study is fucus on change management that is to determine type of decision-making model with the ranking importance of the needs of project stakeholder. In addition, a decision-making method is proposed to evaluate function, performance based on required performance criteria. The QFD-RPC(Quality Function Deployment based on the Required Performance Criteria) can be shared information of function features between participants and check its importance. And also, it is to evaluate the importance ranking of the function, and then to analysis corresponding its performance and required performance criteria, finally to review the suitability whether the defined quality satisfy product' performance compared to the required criteria. Design project can be reduced unnecessary change through the QFD-RPC assessment with a quantitative measurement for design quality.
