Six Sigma is an objective that specializes on the variability needed in the process of specifying the products so that the reliability and the quality meets or even exceeds the requirements of the clients. Six Sigma was designed for the growth and the performance of manufacturing business. It was developed as a way of quality control specifically for companies manufacturing products in large scale. The major reason for this quality controller system was to eliminate the number of defects along with improving the manufacturing procedure. The approach of six sigma was later extended to different other types of companies globally regardless of the size.


Six Sigma concept was developed by Motorola in 1986 as general techniques and tools to advance the processes. Jack Welch used this concept in 1995 as the first concept of industry policy of General Electric, and it is now used by a large number of sectors nowadays.

Six Sigma recognizes and eliminates the imperfections causing features, and also reduces the changeability in business and the process of manufacturing to improve output quality of a manufacturing process. This methodology uses an excellent management method to create a special structure of individuals who can use these procedures like experts within an organization. The organization observes defined steps to enumerate the targeted worth of the project although using each plan of six sigma. An example is where the organization can minimize the time of processing, reduce pollution and production cost while increasing the level of satisfaction to the clients and profits.

How Six Sigma Works in Manufacturing

A sigma ranking can define the development of a manufacturing procedure by specifying its fraction of defect-free produces manufactured or its income. The products that are manufactured through the process of Six Sigma are statistically anticipated to be 100% defect free even if their defect level is equivalent to 4.5. Basically, according to Six sigma doctrine, the accomplishment of a company depends extremely upon continuous determinations and efforts for accomplishing stable manufacturing procedure. These processes factories are supposed to be calculated statistically to be improved by evaluating them. The senior managers of the organization are supposed to be committed to any improvement since the system of Six Sigma is based highly on efforts of the team.

Six sigma Features

The Six sigma key features for development in manufacturing company includes; a perfect focus on measuring and quantifying the financial earnings of the project and the manager’s passionate support and commitment about their guidance in the creation of infrastructure. These features define the role and obligation of every person within the group in improving the process of manufacturing in an organization.

Six Sigma Goals

The main aim of the methodology of Six Sigma is to ensure minimum defects in the process of manufacturing. This ultimate system goal is to have 3.4 defects occurrence per million ventures. Although it appears as an unattainable task, most of the industries that manufacture products accomplish these ultimate goals by embracing this method of manufacturing quality products.
