How to improve product quality and organization of production? How to increase the efficiency of enterprise management? How to improve the quality of scientific research? All these problems are eternal. They were solved a hundred years ago, fifty years, a decade ago, and even now. But all the solutions were done in different ways. In recent decades, new combinations of words and concepts attack the heads and specialists of all areas. Each time there is something new and something long known. The main thing in innovations is a different approach to old problems and methods.
And then there was another new concept – the system of Six Sigma. What is behind these words that remind you of statistical methods?
In the 21st century, the focus of researchers and managers is transferred from the individual development of mathematical study methods to the system of implementation of such methods in the practical activity of enterprises and organizations.
Sigma is a term used in statistics to represent the root mean square (also called standard) deviation degree, deviation indicator of series of measurements or results of the process.
Six Sigma is a statistical concept, based on which the process is measured by the parameters of the failure: at the highest level in Six Sigma number of defects is 3.4 per million of the possible ones. Six Sigma is also a management philosophy, which focuses on the elimination of the failure due to the use of such methods, when the emphasis is on the analysis of the measurements and process improvement.
One sigma corresponds to 691 462.5 cases of failure per million, which corresponds to the release of production without defects only in 30.854%. Of course, these figures are considered to be very poor. If we are seeking to ensure that the processes are operated at three sigma, it means that 66 807.2 possible errors per million are allowed, or we have the release of great products in 93.319% of cases.
Six Sigma is a more intelligent way to manage the entire company or its separate organizational unit. The concept of Six Sigma puts the consumer goods and services in the first place. According to its developers, it helps to find the best solutions, based on facts and data. Six Sigma focuses on three main objectives:
The introduction of Six Sigma has a significant economic impact. Executive Officer of General Electric, Jack Welch, announced in the annual report that in just three years the system Six Sigma has saved the company more than $2 billion.
