CTQCritical to Quality Characteristic a characteristic of a product, service or information which is important to the customer. CTQs must be measurable in either a ‘continuous scale’ manner (. , etc.) or descriptive manner (correct/incorrect, etc.) 關鍵的品質特征 產(chǎn)品,服務或信息的特征對于顧客而言是非常重要的。56Six Sigma Terms and Definitions (cont)3. Opportunity 機會An event which generates an output (product, service or information). 產(chǎn)生一個輸出的事件(產(chǎn)品,服務或信息)4. UnitA discrete item (lamp, invoice, etc.) which possesses one or more CTQ(Note: ‘Units’ must be considered with regard with the specific CTQ(s) of concern by a customer and/or for a specific process) 分立項目(來源,貨物,等)擁有一個或多個 CTQ ?。?知悉:顧客必須考慮到 “UNITS” 有關特殊的 CTQ或特殊的程序) 5.
