Sigma culture can provide strategic methods and corresponding tools for enterprises, and eliminate the defects in all processes from production to sales and from products to services through rigorous, systematic and data-based solutions and methods, thus improving the profits of enterprises.

What is six sigma? In statistics, it is a Greek character, which stands for standard deviation and is used to measure variation. For any enterprise, process variation is one of their biggest enemies, because too many process variations will lead to products and services that cannot meet customer requirements and bring losses to enterprises. The operation process of most enterprises is maintained at the level of 3-4 horses, that is to say, there are 6,200-68,000 defects out of 1 10,000 opportunities that cause defects. Relatively speaking, there are less than 3.4 defects among the 6,543,800+0,000 opportunities for enterprises to maintain 6-horse operation.

6. The basic goal of horse-fitness system method is to establish and implement a measurement-based strategy, and improve the process and reduce variation by implementing six horse-fitness improvement projects. This goal should be achieved by two sets of six sigma system methods: DMAIC and DMADV.

I don't know what that is. I'll help you find it. The following station is more specific. See for yourself!

6 Sigma DMAIC processes (D- definition, M- measurement, A- analysis, I- improvement, C- control) mainly aim at the processes that can't meet the requirements, and make breakthrough improvements. 6 sigma DMADV process (D- definition, M- measurement, A- analysis, D- design and V- verification) is mainly aimed at the development of new products and new processes, so that the performance of new products and new processes can reach 6 sigma level. The above two processes are carried out by six green belts and black belts in Sima, and supervised by six black belt instructors in Sima.
