The Improve Phase of DMAIC Process: Making Change that Lasts
If you want to make lasting changes, you need to know how to use the Improve Phase of the Six Sigma DMAIC Process. The DMAIC Improve Phase is when the rubber meets the road, so to speak.
The History of Six Sigma
Originally developed by Bill Smith at Motorola in 1986, the Six Sigma Training program was created using some of the most innovative quality improvement methods from the preceding six decades. The term “Six Sigma” is derived from a field of statistics known as process capability. The term 6 Sigma refers to the ability of manufacturing processes to produce a very high proportion of output within specification. Processes that operate with “six sigma quality” over the short term are assumed to produce long-term defect levels below 3.4 defects per million opportunities. Six Sigma’s goal is to improve overall processes to that level of quality or better.
