“质量功能展开”简称 QFD,是质量管理的辅助工具之一。日本新标准 JIS Q 9025对 TQM 活动中普遍应用的质量功能展开方法作出了统一规定。日本标准协会在公布该标准时以附件发表了一篇《解说》,对该标准的有关情况作了全面说明,在此摘其要点作一介绍。本文首先简要说明了 JIS Q 9025等辅助工具类标准的制定宗旨和编写方针,然后重点介绍了“质量功能展开指南”的要点,包括 JIS Q 9025的主要用途、适用范围、内容结构和术语定义原则等概要情况、从“需求质量重要度和需求质量权重”到“机理展开表和分系统展开表”等11条术语的解释、以及关于“展开和变换”、“展开表和一览表”、“质量功能展开的整体构想图”等起草过程中重点讨论的问题。文章最后指出了质量功能展开同 JIS Q 9001和 JIS Q 1 4001等现有管理体系的绩效改进之间的关系,以此进一步强调 QFD 在质量管理中值得期待的辅助作用。
“Quality Function Deployment ” QFD is one of the auxiliary tools for quality management. The new Japanese standard JIS Q 9025 provides a unified approach to the general application of quality functions in TQM activities. The Japan Standards Institute published a “commentary” as an annex when the standard was published, giving a full account of the relevant circumstances of the standard and giving an introduction of the key points of the standard. This paper begins with a brief description of the objectives and guidelines for the development of standards for assistive tools such as JIS Q 9025 and highlights the main points of the “Quality Function Deployment Guide”, including the main purpose, scope, content structure and terminology of JIS Q 9025 Definition of principles and other summary situation, from the “quality of the importance of the demand and quality of the weight ” to “mechanism to expand the table and sub-system to expand table ” and other 11 terms of the explanation, as well as on the “expansion and transformation ”Expand Table and List “, ”Overall Concept of Quality Function Deployment " and other issues focused on the drafting process. Finally, the paper points out the relationship between the expansion of quality functions and the performance improvement of the existing management systems such as JIS Q 9001 and JIS Q 1 4001 to further emphasize the QFD’s worth supporting role in quality management.
