Six Sigma Quality - Essay Example Wide spread of this concept has led to unreasonable growth of supervising personnel. Up to 40 and more percent of strength of workers involved in manufacture, that in its turn has caused irrational increase of expenses for quality management and, hence, has lowered efficiency of production. As a result in 20th the attention of managers has moved from rejection of production in the process of its yield to quality control in the process of manufacture. The most significant role of this stage was played by Mr. Shuhart, Western Electric company's employee, who suggested to apply statistical methods (known now as Shuhart control charts), which allowed to increase qualitative products yield in the process of production. However improvement of separately taken process has been often restrained by inefficiency of other fields of companies' activity. This problem has been solved owing to activity of Japan manufacturers who, having collided with a strong competition from the side of foreign pr oducts, have decided to take steps for improvement of quality at simultaneous decrease of net cost. They have invited American experts Deming and Juran, who worked the program consisted of 14 items, and based on improvement of entire company's management system, on direct participation of management in all quality issues of company, and on stimulation of personnel to qualitative labor activity. It appeared a 'Zero Defect' concept. New approaches have led to growth of quality produced goods and decrease of expenses for their manufacturing. However the qualitative product still was understood as production being congruent with norms, established by the manufacturer, instead of by consumers. In this connection the high-quality goods sometimes did not go through. From the middle of 60th of twentieth century manufacturers were focused on better satisfaction of consumers' demands. At this stage appeared the theory of reliability and system of the automated designing of works. As a result of analysis of industrial systems it was found out, that the reason of a better part of defects (about 80 %) is insufficient quality of design works. That is why before testing of samples in real conditions they began to conduct mathematical modeling of products and processes of manufacture properties. It has considerably raised efficiency of developmental works.Six Sigma Today companies use various technologies for decrease of costs, satisfaction of requirements of clients, reduction of terms of development and yield of production to the market. In order to transform consumers' demands into technical requirements to products and their manufacture, it is often conducted the functional-cost analysis (the analysis of expenses for manufacture of a product with the purpose to decrease its cost price); the analysis of opportunities of occurrence and influence of defects of a developed product on consumers; the is functional-physical analysis (the analysis of quality of technology projects, principles of product and its components working). At this stage the quantity of concepts of quality management grows. Despite of otherness of names and used tools, they have been based on the same principles. Quality can be presented in the form of a five-pointed star, in the basis of which lays documented, the formalized organizational system of quality manage
