What is Six Sigma?

So, what is Six Sigma, and why it's so popular?

Six Sigma Logo
Six Sigma is a business management strategy that provides quality management methods, which go from business and cost-benefit analysis, thought-process mapping customer surveys, to control charts and regression analysis.

Six Sigma puts on measurements as the starting point of culture change and decision making processes, which is what makes it different from other business models.

There are four different levels of Six Sigma - Yellow Belt, Green Belt, Black Belt and Champion:

Yellow Belts have basic knowledge of Lean Six Sigma, and usually carry out performance improvements within their teams.

Green Belts are certified and trained at a more advanced level of Lean Six Sigma. They tackle change within their business in addition to their other responsibilities. 

Black Belts are trained at an even more advanced level and are fluent in the use of the Lean Six Sigma approach and tools. They deliver major performance or efficiency transformations for a business. They usually are Change Leaders for a business.

Champions are those that sponsor performance improvement projects. They are usually managers of processes and business areas that are trained to pinpoint where transformations / improvements are needed to and help remove barriers to the implementation of changes.

The Six Sigma method has had great success and is widely used by all types of organizations. Demand for Six Sigma Green Belt and Black Belt certifications has increased dramatically at Firebrand Training especially with the combination of the Green Belt and Black Belt, which will get you both the certifications in just 10 days.

George Eckes gives an effective explanation and introduction of what Six Sigma is through the video below.

He uses an interesting story called 3 blind men and an elephant to describe why Sig Sigma is so important. The story goes like this: 

Three blind men touch different parts of the elephant and draw very different conclusions. One touches the tusk and says it’s a spear; the other touches his torso and says it’s a wall, and the third blind man touches the tail and says it’s a snake.

The point of the story is that depending on your perspective and viewpoint, it can mean very different things. Six Sigma is a metric, it’s an improvement methodology, it’s a management philosophy and it creates a common language throughout the whole organisation.
