What are the 6 sigma levels?

Training in Six Sigma helps validate professionals by demonstrating their ability to recognize risks, errors, or defects in a business process and then eliminate those issues. Six Sigma is a certification program that aims to educate individuals in the process of analyzing processes and outcomes in the pursuit of decreasing waste and eliminating defects. The program’s objective is to teach participants how to analyze procedures and results. The process of becoming certified consists of multiple stages, the lowest of which is a primary end user and the highest of which is a master Six Sigma user.

Six Sigma is a methodology that helps businesses enhance their manufacturing processes, reduce or eliminate faults, and ensure that their products are of the highest quality.

Individuals typically need a particular amount of experience under their belts in addition to being able to demonstrate their degree of expertise in order to be eligible for a Six Sigma certification as well as training. A specialist in process improvement is something you may become with the help of the certification, which will also boost your credibility.

There are several degrees of six sigma certification, including White Belt, Yellow Belt, Green Belt, Black Belt, Master Black Belt, and champion. White Belt is the lowest level, and Champion at the top.

White Belt

White Belt Professionals are those who have not participated in a formal certification program or received additional training. They are referred to as White Belts in Six Sigma. A single session that provides an overview of important methods and vocabulary for LSS demonstrates to employees at all levels of an organization how their contributions affect the business’s ability to produce results that are efficient and dependable. White Belts participate in projects and problem-solving tasks linked to quality management and waste reduction, using the foundational knowledge they have acquired. White Belts are also called Green Belts.

Yellow Belt

The attainment of the Yellow Belt certification demonstrates an understanding of Six Sigma principles that extends beyond the essentials that are covered in the White Belt program. Yellow Belts may have participated in training sessions that lasted for one or two days, gaining the knowledge necessary to be assigned to a project as fully contributing team members in the process. They might direct initiatives with a limited scope and provide assistance to managers at higher belt levels.

Green Belt

Earning a Lean Six Sigma For professionals to be eligible for Green Belt certification, they must first complete a comprehensive training program that teaches them the Six Sigma methodology for developing and improving products, services, and processes. They become skilled in the application of problem-solving frameworks such as DMAIC, which stands for define, measure, analyze, improve, and control. This cycle of improvement outlines a sequence of activities that must be completed in order to discover the issues that exist within a business process, establish helpful metrics for assessing improvements, investigate pertinent data, implement remedies, and finally maintain the outcomes over time.

Green Belt training is beneficial for individuals who work in positions such as project management, health care administration, or financial management because it provides them with an understanding of performance metrics as well as tools such as control charts and Failure Modes and Effects Analysis (FMEA). After receiving their certification, experts are then able to take responsibility for projects while also establishing linkages between LSS concepts and the objectives of their organization. They are able to put leadership skills to use, discover opportunities to cut waste and get helpful insights from data.

Black Belt

It is possible for leaders to advance their talents to the next level by obtaining Six Sigma Black Belt certification after they have finished the courses required for the Green Belt. This more advanced training involves previous knowledge of LSS techniques as professionals develop the abilities they need to plan, lead, and explain increasingly complicated and extensive projects or organizational transformations. Students who take a class at the Black Belt level have a profound comprehension of how to implement Lean concepts throughout an entire organization, conduct statistical research, and supervise the work of a group of Green Belts working on projects.

Professionals get the opportunity to demonstrate what they’ve learned and get practical experience by working on a project for either their current business or a charitable organization while taking the Black Belt level of training. Students gain the skills they need to make their businesses more efficient and boost customer satisfaction by writing down a project charter, collecting data, and applying Six Sigma technologies in a real-world environment. These activities take place in an authentic setting.

Those who have achieved the rank of Lean Six Sigma Black Belt are qualified to carry out LSS projects, manage team dynamics, and monitor results. They manage quality improvement and Lean initiatives, both of which have the potential to have a substantial impact on the overall productivity of the firm.

Master Black Belt

An experienced Black Belt who possesses great leadership and problem-solving skills has the potential to advance their training and earn the rank of Master Black Belt in LSS. This distinction shows that a professional takes a comprehensive view of strategy throughout a whole organization, coordinating teams across functional areas


A Champion is a senior-level manager who guides the development of LSS strategy and oversees its implementation. Champions are individuals who, based on the goals that are set by executive leadership, are tasked with ensuring that all measures to reduce waste and eliminate defects are brought into harmony with the requirements of a growing business. These supervisors provide guidance and feedback to the LSS implementation leaders, with the assistance of Master Black Belts, and monitor the leaders’ overall development.

Where to begin is determined by three different criteria. Let us discuss them in detail below:


Any student who plans to pursue a degree in the humanities, such as English, Art, Music, or Journalism, should begin their training at the Yellow Belt level. It concentrates mostly on the conceptual problems associated with the Lean belt. It is important to consider the when, where, why, and how. These ideas can be put into practice with the use of statistical evidence, but doing so is the responsibility of Green Belts and higher. This Yellow Belt training has been an excellent method to get started learning about the subject matter.

Graduates of liberal arts programs who also have experience in the social sciences, economics, and natural sciences are eligible for the Green Belt. Math and statistics have been introduced to a good number of people. As a result, this will make it much simpler to comprehend the core statistical principles that are presented in the Green Belt.

If you want to go ahead to the Green Belt without having to go through the Yellow Belt first, you need have a good grasp of statistics and mathematics.

Engineers that come from backgrounds that are strong in the quantitative analysis should have no issue passing the Green Belt exam. They might also think about getting the Black Belt, especially those who are exceptionally good with statistics.

If you have an education in business, you should make your way immediately to the Green. Yellow could be a good starting point for students majoring in marketing or management. It all relies on how comfortable you are dealing with statistical information.


It is advised that you pursue the Black Belt if you have experience with Lean and Quality management, a solid comprehension of statistics and mathematical reasoning, have not taken a break from formal education in a significant amount of time, and have a lot of work history.

On the other hand, a significant number of persons who switch jobs have been out of school for some time and are unfamiliar with the process.

If you feel confident working with statistical information, you should start with the Yellow Belt and maybe move on to the Green Belt later. It’s possible that the Black Belt will be too challenging and frustrating for you. It is preferable to start at a level that is manageable for you and gradually increase it rather than allow yourself to become frustrated and give up.
