Six Sigma Case Studies, Examples, and Training Material

Following the definition of Six Sigma below are articles on Six Sigma below show examples, applications, and a comprehensive definitions and application of its tools.

What is Six Sigma?

Six Sigma originated as a set of practices designed to improve manufacturing processes and eliminate defects, but its application was subsequently extended to other types of business processes as well. In Six Sigma, a defect is defined as any process output that does not meet customer specifications, or that could lead to creating an output that does not meet customer specifications.

Bill Smith first formulated the particulars of the methodology at Motorola in 1986. Six Sigma was heavily inspired by six preceding decades of quality improvement methodologies such as quality control, TQM, and Zero Defects, based on the work of pioneers such as Shewhart, Deming, Juran, Ishikawa, Taguchi and others.

The term “Six Sigma” comes from a field of statistics known as process capability studies. Originally, it referred 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 (DPMO). Six Sigma’s implicit goal is to improve all processes to that level of quality or better.

In recent years, some practitioners have combined Six Sigma ideas with lean manufacturing to yield a methodology named Lean Six Sigma.

how to pay lower taxes

What motivates an individual and an organization is sometimes not aligned with the rewards system we put in place to encourage a higher level of performance. We see this dynamic in the cigarette sin tax situation where a higher sin tax does not lead to less smoking. Thinking about the specific Lean Deployment or Six [...]

The second phase in the Six Sigma Define-Measure-Analyze-Improve-Control (DMAIC) methodology is Measure. In a previous post, we discussed the Define Phase in the Six Sigma DMAIC Methodology. During the Measure phase, the focus shifts from “do we agree that X is a problem” to “what’s the phenomena that is happening such that it is a [...]
