Development of Quality Management – Six Sigma. The development of quality management as a science is not such a long history. Back in the early twentieth century American analyst Walter Shewhart brought to his superior technique statistical analysis of the production process and the identification of marriage in the workplace, which were later called Shewhart card. The chief did not understand, and Walter Shewhart was left with nothing, and later he went to Europe, where it method was received with understanding and started implementing Shewhart charts in production, and only then was invited back to the United States so he could implement his own method. In the mid-twentieth century, Japanese companies began to implement the methodology of Deming, and quite successfully, if we consider that the defeated postwar Japan, which has no resources left on the cutting edge of world production. Thus, quality management, as a science has a history of no more than a century now, the latest trends in this theory is the method of six sigma. Sigma – is the mean square of the statistical sample. That is, the system catches the change with statistical analysis.

The theory of six sigma is based on six items that were encountered in previous methods. The first – a manifestation of genuine interest to the client, it does not appear that when we go in with you store, you run to the manager and shouted "help you", not a sincere attitude to the customer – is monitoring and analysis of what the client needs, not what we do, and then the client will buy. The second – control is based on the data and facts, not based on assumptions that may happen with a certain probability. The third – focus on the process, a constant process control, process improvement, process improvement. The whole cycle production can be divided into processes, allocate and manage the process – it is based on the process approach to management.
