六西格瑪管理的執行步驟內容摘要：
The Origins of SixSigma
　　It originated in the 1980's as Motorola responded to the threat of Japanese competition 　　which had far lower defective rates. The approach spread to AlliedSignal and to General 　　Electric, whose Chief Executive Officer, Jack Welch, has been the most passionate advocate of SixSigma. Since introducing it worldwide in 1996, GE has made over $1 billion of cost savings.
Motorola公司認為數據是滿足顧客的關鍵，他 們常說：
　　1.如無法用數據表示我們所知的,那麼我們對它 所知不多
　　 (If we cannot express what we know in numbers, we don't know much about it)
　　2.如果對它所知不多，就無法控製它 (If we don't know much about it, we cannot control it)
　　3.如果我們不能控製它，那隻有靠運氣了 (If we cannot control it, we are at the mercy of chance)
質量改善的流程：
　　1. 定義產品或服務
　　2. 鑒定顧客及其需求
　　3. 列出滿足顧客需求所需之條件
　　4. 定義(規劃)流程
　　5. 防範流程錯誤並消除浪費
　　6. 確保持續改善
