DMAIC模型的应用是一个循环过程 DMAIC模型作为实施6σ的操作方法，它的运作程序与6σ项目的周期及工作阶段紧密结合。
DMAIC模型从界定到控制不是一次性的直线过程，在运用当中有些技术与方法被反复使用。
DMAIC模型的应用是实现6σ水准的一个循环过程。
只有不满足现状，勇于创新，不断改进，才能在6σ管理中取得卓越成就。 DMAIC适用范畴
6西格玛改进方法DMAIC适用于那些已经存在但是不能满足顾客或不能有效运行的流程或产品。
The DMAIC methodology should be used when aproduct or process is in existance at your company but is not meetingcustomer specification or is not performing adequately. For DMAICmilestone reviews, there are certain deliverables, checkpoints,questions and concerns that the Black Belt and improvement team shouldbe aware of prior to a tollgate/milestone review.

The Six Sigma methodology is widely used in many top corporations in the United States and around the world. It is normally defined as a set of practices that improve efficiency and eliminate defects.
Six Sigma has been around for more than 20 years and heavily influenced by TQM (total quality management) and Zero Defect principles. In its methodology, it asserts that in order to achieve high quality manufacturing and business processes, continued efforts must be m.ade to reduce variations.
The Six Sigma system strives to reduce these variations in both business and manufacturing and in order to do so; these processes must be measured, analyzed, controlled and improved upon. In order to improve upon these processes, the Six Sigma system requires sustained commitment from an entire organization - especially from the top echelons to help guide lower rung workers and policies.
It should be noted that the Six Sigma system derives its name from the high quality output that it strives to achieve. Six Sigma refers to a defect level of lower than 3.4 defects per million opportunities. This methodology has saved businesses around the world billions in dollars due to its low defect output. For instance, since 1986, Motorola has stated that the Six Sigma system has saved them $17 billion dollars. Six Sigma is a registered trademark of Motorola Corp.
For those that use the Six Sigma system there are two major methodologies. They include DMAIC and DMADV. In this article DMAIC will be covered. DMAIC was developed by Edwards Deming and is useful in improving an existing business process to reduce defects. The DMAIC methodology includes five steps including; Define, Measure, Analyze, Improve and Control. Here is some information regarding each step.
Define: Define is the first step in the process. In this step, it is important to define specific goals in achieving outcomes that are consistent with both your customer's demands and your own business's strategy. In essence, you are laying down a road map for accomplishment.
Measure: In order to determine whether or not defects have been reduced, you need a base measurement. In this step, accurate measurements must be ma.de and relevant data must be collected so that future comparisons can be measured to determine whether or not defects have been reduced.
Analyze: Analysis is extremely important to determine relationships and the factors of causality. If you are trying to understand how to fix a problem, cause and effect is extremely necessary and must be considered.
Improve: Making improvements or optimizing your processes based on measurements and analysis can ensure that defects are lowered and processes are streamlined.
Control: This is the last step in the DMAIC methodology. Control ensures that any variances stand out and are corrected before they can influence a process negatively causing defects. Controls can be in the form of pilot runs to determine if the processes are capable and then once data is collected, a process can transition into standard production. However, continued measurement and analysis must ensue to keep processes on track and free of defects below the Six Sigma limit.作者: yywilly 时间: 2008-11-28 17:22
