The name is derived from the Greek symbol “sigma” or “σ” which is a statistical term used to identity process derivation from the process mean or target. Six Sigma is a set of tools and techniques used by companies to enhance production process and eliminate defects. It is a popular ...
Figure 1: Six-Sigma Process with +1.5s Shift vs. Centered Three-Sigma Process How Six Sigma works Let's take a closer look at the difference between three-sigma and six-sigma processes under the assumption of normality, which is critical to the calculations that follow. (The assumption of ...
The concept of Lean Six Sigma is a combination of both the Lean and Six Sigma. The aim of this review paper is to define the meaning and basic principles of Process Improvement Techniques. For this purpose, Process Improvement Techniques focuses on Lean, Six Sigma and combined approach as ...

Six Sigma methodologies The above principles can be applied with one of two improvement methodologies: Six Sigma DMAIC and Six Sigma DMADV. Each term's name is derived from the major steps in its process, but each has its own use.
The term six sigma is derived from a field of statistics known as process capability studies and comes from the idea that if there are six standard deviations between the average and the nearest defect, there will be practically no errors. Originally, it referred to the ability of manufactu...

Lean Six Sigma is derived from a combination of Lean and Six Sigma principles. Lean focuses on removing waste of physical and personnel resources by identifying the causes of defects, overproduction, waiting, non-utilized talent, transportation waste, inventory waste, waste of motion, and extra pr...
