What is the difference between green belt and black belt in six sigma?

There are different levels of proficiency that one can achieve to become certified in Six Sigma. These levels of certification demonstrate a mastery in the principles embodied by Six Sigma. Certification levels range from the White Belt to the Black Belt. They differ primarily in the level of knowledge obtained. As the experts at C Tek can explain, the level of training that you get should meet your goals and objectives. For those seeking advanced levels of Six Sigma knowledge, a Green Belt or Black Belt certification is ideal.

Sigma Belt Levels

Six Sigma certification starts with the White Belt, which is the beginner’s belt. At this level, employees have a basic knowledge of Sigma methods and their impact on the company. Next is the Yellow Belt, which teaches professionals more about project management and process mapping. The Green Belt certification develops expertise in Sigma concepts and tools. The Black Belt develops Sigma mastery and requires completion of projects and exams.

Green Belt

Individuals who obtain a Green Belt level of certification generally intend to work as part of a larger Six Sigma team. They will learn considerable amounts of information through the program and will work under the direction of individuals who are Black Belt certified. Employees who are certified at this level perform many essential functions within the company. Ultimately, they are responsible for implementing projects within a company and making sure they are completed fully and on time. Through training they learn the basic principles of Six Sigma, which includes project selection, project definitions, measuring systems, process control plans, process mapping, and reviewing projects. In order to become certified at this level, employees must typically complete a real-world project and an exam.

Black Belt

The Black Belt level of Six Sigma certification is the highest level. Individuals who receive their Black Belt are trained in a process called “define, measure, analyze, improve, and control,” or “DMAIC” for short. These steps are the five main pillars used by companies to resolve and overcome problems that arise in manufacturing and industry. Ultimately, they help a company reduce waste, become more efficient, and improve customer relations. Therefore, individuals who learn this process are usually in a management position or intend to lead a team. Another area of focus in the Black Belt program that distinguishes this level from Green Belt is business cost and finding ways to reduce unnecessary expenses.

The Black Belt is also available at the Master level. Training for a Master belt is more intensive than with the other Sigma belt levels. Candidates for the Master must pass an exam. They must also complete at least 10 projects. Most candidates must also have at least five years’ worth of experience in training before they can obtain their belt.
