Six Sigma is an effective, sought after management strategy, usually applied by large and successful companies that improve the quality of processes by identifying errors in the system or flow of work. Simply put, improving the company’s process + eliminating errors = higher quality and cost savings.
In the past, companies thought that increasing the quality of output may cause the business more money, but in truth, Six Sigma shows that doing so cuts a big amount of expenses because of savings in repairs, damages, and customer complaints. Naturally, all of these register a positive growth index for the company.
Six Sigma improves customer satisfaction and increases return of investments through a set of quality management methods while creating facilitators termed as Champions, Black Belts, and so forth, to implement the strategies. It creates a hierarchy, like a special infrastructure made of people to carry out the specific and identified projects of the organization following a smooth, sequence of steps, each with its own goal to meet like increasing customer satisfaction, decreasing costs of production, or increasing profits.

Emphasize on Quality Management

It uses quality management as its main tool, coupled with statistical methods to reach these goals. Originally, Six Sigma means a maturity of a manufacturing process that follows a statistical model described as sigma ratings which indicates the quality of outputs produced. To be technical about it, one Six Sigma process includes products which are manufactured to be 99.99966% free of errors – almost with the perfect standard.
All of these reflect how distinct Six Sigma is and why every company can benefit from it. For one, it is based on a systematic and scientific process that creates goals which are both measurable and quantifiable, which makes decisions and evaluations strong and reliable because they are based on verifiable data rather than assumptions.
Furthermore, Six Sigma is based on the following principles:

Any type of organization can certainly use some fixes to improve the way they implement their work to achieve higher goals and minimize errors. With Six Sigma, the goals that the company has postulated will sure be met because clear strategies and methodologies, implementation roles, and firm commitment are drawn to realize them all.
