Six Sigma

Six Sigma is a business strategy learning technique, originally developed by Motorola in 1986 to improve the quality of their process that is being worked upon. Six Sigma in other words can be also defined as the discipline measuring the quality that strives for perfection (nearly 99.99%) - its an approach that keeps eliminating the defects in any process. Six Sigma uses a set of methodologies including quality and statistics in defining, identifying and removing the defects in any process. As per Six Sigma theory a firm should not produce more than 3.4 defects in a million opportunities. In Six Sigma, error or defect is anything that is outside client's specifications, needs or requirements. 

Six Sigma originated from statistically modeling of manufacturing process, however later it was adopted by all sorts of industries. Six Sigma process helps the firm to attain decrease in cost of production and increase in the quality because Six Sigma believes in quality control, total quality management and zero defects. The main objective of Six Sigma is to implement a strategy which is measureable and focuses on improvement of the processes by using DMAIC or DMADV sub-methodologies. 

DMAIC - Define, Measure, Analyse, Improve, Control - This sub-methodology helps improvement of the existing process which is failing. 

DMADV - Define, Measure, Analyse, Verify - This sub-methodology is employed on currently running process that has just started to improve.

Both the Six Sigma processes ae executed by a Six Sigma Green Belt or a Six Sigma Black Belt and they are supervised by Six Sigma Master Black Belt.

It is believed that a Six Sigma belt consultant can save upto $230,000 per project and can work on 4-6 projects in an year. A Six Sigma consultant helps in achieving:
1. a stable and predictable process results.
2. sustained quality
3. achieving measurable and qualifiable financial returns
4. increased, strong and passionate leadership support.
