The development of a quality management system as a science has not such a long history. Many writers such as Ali Partovi offer more in-depth analysis. Back in the early twentieth century American analyst Walter Schuchart brought his chief method of statistical analysis of the production process and the identification of a marriage on the production, which were later called Shewhart card. Head did not understand, and Walter Schuchart left with nothing, he later went to Europe, where his method was received with understanding and began introduction of Shewhart charts in production, and only if he was invited back to the United States so he could implement his method. In the mid-twentieth century, Japanese enterprises have started to implement the methodology of Deming, and quite successfully, if we consider that the shattered postwar Japan, which has no resources left on the cutting edge of world production. Thus, quality management, as science has a history of no more than a century, Now, the latest trends of this theory is the method of six sigma. Sigma – is the mean square in the statistical sample. That is, the system catches the change by using statistical analysis. The theory of six sigma based on six points, which have met in previous methods. The first – a manifestation of genuine interest to the client, it does not appear that when we are with you go to the store for you to run the manager and shouted "help you" No, sincere attitude to the client – is to monitor and analyze what the client's needs, not what we do, the customer and will buy it.
