“The quality performance” is the foundation stone of all types of industries. The growth of an industry depends on its performance quality. So checking out of the performance quality of an industry is something which is inevitable. “SIX SIGMA” – The statistical representation, is a process of quality measurement, which helps the organization in the improvement of their quality.

Six Sigma is a systematical process of “quality improvement through the disciplined data-analyzing approach, and by improving the organizational process by eliminating the defects or the obstacles which prevents the organizations to reach the perfection”.

Six sigma points out the total number of the defects that has come across in an organizational performance. Any type of defects, apart from the customer specification, is considered as the defect, according to Six Sigma. With the help of the statistical representation of the Six Sigma, it is easy to find out how a process is performing on quantitatively aspects. A Defect according to Six Sigma is nonconformity of the product or the service of an organization.

Since the fundamental aim of the Six Sigma is the application of the improvement on the specified process, through a measurement-based strategy, Six Sigma is considered as a registered service mark or the trade mark. Six Sigma has its own rules and methodologies to be applied. In order to achieve this service mark, the process should not produce defects more than 3.4. These numbers of defects are considered as “the rate of the defects in a process should not exceed beyond the rate 3.4 per million opportunities”. Through the Six Sigma calculation the number of defects can be calculated. For this there is a sigma calculator, which helps in the calculation.

In order to attain the fundamental objectives of Six Sigma, there are Six Sigma methodologies to be implemented. This is done through the application of Six Sigma improvement projects, which is accomplished through the two Six Sigma sub-methodologies. Under the improvement projects came the identification, selection and ranking things according to the importance. The major two sub-divisions of the improvement projects are the Six Sigma DMAIC and the Six Sigma DMADV. These sub-divisions are considered as the processes and the execution of these processes are done through three certifications. The three types of certifications used for the execution of the Six Sigma DMAIC and Six sigma DMADV are:

“Six Sigma Green Belts and Six Sigma Black Belts, which is overseen by Six Sigma Master Black Belts”.

The Six Sigma ensures the quality control, total quality management and zero defects. Through the implementation of the Six Sigma it is made sure that the goals are set on the improvement of all processes to reach the level of better quality. “The Six Sigma” shows the organization’s ability of highly capable processing in producing the outputs within the limited specifications. There fore it can be said that the processes that operates with the Six Sigma quality, is able to produce a quality products at a low rate of defects.

When a process attains the certification of Six Sigma quality, it is clear that the organization has attained the standard deviations form the means of the production till the specific limitations, and so can make sure that there is no room for the items to fail to meet the specifications. Altogether we can consider the Six Sigma as the professionalizing of the quality management functions
