质量功能展开(QFD)方法与故障模式及影响分析(FMEA)技术以不同的思维方式指导产品的质量设计.通过对QFD方法与FMEA技术优缺点的分析,将二者进行技术整合,借助于QFD分析判断,挑选出对产品的用户需求至关重要的质量特性,确定其重要程度;而通过与QFD技术结合,FMEA对选出的关键部件进行故障模式及影响分析,确定其潜在影响,鉴别设计上的薄弱环节,从而将FMEA中的信息透过基于故障模式的需求重要度直接地反馈至质量层中,获得了新的、更合理的用户需求重要度排序.具体实例详细验证了该整合框架模型的有效性和优越性,说明了两者的整合应用可以充分发挥各自的优点,弥补各自的不足.

Based on the basic introduction of Quality function deployment (QFD) and Failure Mode and Effects Analysis (FMEA), the virtues and limitations of QFD and FMEA are analyzed. According to the complementarity of QFD and FMEA, the frame model which measures consumers' requirements based on combination of QFD and FMEA is developed. The important quality characteristics for consumers' requirements can be selected by QFD, the failure mode and the effect of key parts can be analyzed by FMEA. Thus the Consumer's Requirements Importance based on FMEA is directly fed back to the House of Quality, and a more reasonable sequence of Consumer's Requirements Importance is acquired. Finally, the usability and advantage of the frame mode are verified through a calculation example.
