CTQ是什么意思
CTQ(Critical-To-Quality)的意思是品质关键点。该概念常在six sigma (六西格玛)管理中被提到。
在Six Sigma (六西格玛)中,通常用Y来表示。很多公司都是把其作为一个输出的衡量性指标(Outcome Indicator)。
举个例子来说,麦当劳顾客减少,此时的关键指标就是平均每天顾客人数(person/day)不同的项目有不同的指标的。

六西格玛(Six Sigma)又称:6σ,6Sigma,不能使用大写的Σ,西格玛(σ)是希腊文的字母,在统计学中称为标准差,用来表示数据的分散程度。
其含义引申后是指:一般企业的瑕疵率大约是3到4个西格玛,以4西格玛而言,相当于每一百万个机会里,有6210次误差。如果企业不断追求品质改进,达到6西格玛的程度,绩效就几近于完美地达成顾客要求,在一百万个机会里,只找得出3.4个瑕疪。
六西格玛是摩托罗拉公司发明的术语,用来描述在实现质量改进突破时采用的目标和过程。西格玛(σ)是统计员使用的希腊字母,指标准偏差。术语六西格玛指换算为百万分之3.4的错误/缺陷率的流程变化(六个标准偏差)的尺度。

英文释义
CTQs (Critical to Quality) are the key measurable characteristics of a product or process whose performance standards or specification limits must be met in order to satisfy the customer. They align improvement or design efforts with customer requirements. CTQs represent the product or service characteristics that are defined by the customer (internal or external). They may include the upper and lower specification limits or any other factors related to the product or service. A CTQ usually must be interpreted from a qualitative customer statement to an actionable, quantitative business specification. To put it in layman's terms, CTQs are what the customer expects of a product... the spoken needs of the customer. The customer may often express this in plain English, but it is up to us to convert them to measurable terms using tools such as DFMEA, etc.
