The fundamentals of Six Sigma are intended to improve the performance of manufacturing industry. It was initially established as a kind of quality control especially for large scale manufacturing companies. The main aim of this quality control system was to improve the manufacturing processes along with reducing the number of defects found in them. Later on, the methodology of Six Sigma was extended to various other types of industries irrespective of their size all over the world. The role of six sigma is better to understand by going through its concepts.
Working of Six Sigma:
The terms linked with manufacturing industry linked with statistical exhibiting of manufacturing processes invented the term Six Sigma. A sigma rating can describe the development of a manufacturing process by indicating its ratio of defect-free products created or its profit. Nearly 100% products manufactured through Six Sigma process are statistically expected to be defect free even of the level of their defect is equal to 4.5. The goal of Six Sigma was set by Motorola for all of its manufacturing processes, and to bring quality in the manufacturing process and all of its engineering and management practices take this goal by-word for its achievement.
