摘要

六標準差管理為突破品質改善之創新手法，以減少變異。製程能力分析乃分析變異對製程影響的方法之一。平均值偏離目標值與變異數可對應於在六標準差管理中之標準差水準，予以衡量製程能力指數。在本研究中，當目標值不在規格內之中心值時，六標準差管理中之標準差水準可連結於製程能力指數。管理者可藉此衡量六標準差管理之管理績效。

Six sigma management is an innovative approach of breakthrough quality management in order to reduce the variation. The process capability analysis is one of the methods to analyze the effect of variation on the process. The deviation of the mean from the target value and the variance for specific sigma level in six sigma management can be used to measure the process capability indices. In this paper, the level of six sigma management will be linked with the process capability indices when the target value is not on the center within the specification. The managers can measure managerial performance of six sigma management.
