“Congratulations! We are pleased to inform you that you have passed the ASQ SSGB examination.”
…but I’m relieved it did. 😀
For the uninitiated, Six Sigma is a business management strategy originally developed by Motorola in 1986, and is now widely used in many sectors of industry.
Six Sigma seeks to improve the quality of processes by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes using a set of quality management tools, including statistical methods. This is accomplished in a defined sequence of steps with quantified financial targets (cost reduction and/or profit increase).
The term Six Sigma originated from terminology associated with manufacturing, specifically terms associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield, or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defects per million opportunities). Motorola set a goal of “six sigma” for all of its manufacturing operations, and this goal became a byword for the management and engineering practices used to achieve it.
