The Six Sigma program works to standardize a company’s problem-solving approach and shape the way it ideates process solutions. To accomplish this goal, the methodology follows five data-driven stages — Define, Measure, Analyze, Improve, and Control (DMAIC). To complete a Six Sigma certification program, a professional must master each of these concepts, whether pursuing a Yellow Belt, Green Belt, or Black Belt certification level.

Similar to how the Lean Six Sigma manufacturing philosophy can help industry leaders improve processes by minimizing unplanned downtime and maximizing equipment output, Six Sigma belt levels apply structured techniques to further assist manufacturers by reducing labor costs, decreasing product defects, enhancing the customer experience, and developing strong leaders.

To help you learn more about how Six Sigma certification belts could benefit your company, this article will explain the background of Six Sigma, the different belt colors and certification levels, the Six Sigma belt order, and the impact this methodology can have on manufacturing. Keep reading to explore the career certification paths within Six Sigma quality management and how these methods can help your operation minimize inefficiencies and defects.

Why Is the Concept Called Six Sigma?

The name 6 Sigma comes from the bell curve used in statistics, in which one sigma symbolizes one standard deviation from the mean. When a process exhibits six sigmas — three below the mean and three above it — the defect rate is extremely low. Because this approach uses statistics to measure the capability of a process, referring to the concept as 6 Sigma methodology suits its purposes.

The 6 Sigma process was developed in the early 1980s by Bill Smith at Motorola to help measure the company’s defects and improve overall quality. Since its inception, Six Sigma process improvement has been successfully implemented by General Electric (GE) to save money by reducing waste and enhancing product quality.

Due to the success GE enjoyed with 6 Sigma implementation, the methodology has become widely popular with other organizations. Numerous companies worldwide now rely on this approach to improve their operations and drive positive changes in the workplace.

What Are the Six Sigma Belt Levels?

Below is a general description of each certification level a professional can achieve within the Six Sigma program:

1. White belt: If a worker has not completed any formal Six Sigma belt training or certification program, they are considered a Six Sigma White Belt. Although they have yet to receive official instruction, white belts generally have a basic understanding of core Six Sigma principles.
2. Yellow belt: A Six Sigma Yellow Belt certification has been exposed to Six Sigma concepts that go a bit deeper than the fundamentals. A yellow belt may have gone to one- or two-day training sessions to develop the knowledge needed to work on projects as a fully contributing team member, guide smaller projects or directly assist managers of higher belt levels.
3. Green belt: To earn the green belt status, professionals must attend a complete course that outlines the Six Sigma methods of developing and improving processes, services and products. Through a Six Sigma green belt course, workers learn to apply problem-solving frameworks like DMAIC methodology become better prepared for more involved roles within company projects.
4. Black belt: A Six Sigma Black Belt certification takes professionals to the next level by supplying them with advanced training on the skills needed to plan, explain and lead more complex projects or expansive organizational adaptations. Six Sigma black belt training goes over how to implement Lean Six Sigma principles and supervise projects effectively. Once students have gained hands-on experience and demonstrated they can oversee a large project and manage a team in a real-world context to improve productivity, they will earn their black belt.
5. Master black belt: After becoming a seasoned black belt, leaders can advance further by becoming a master black belt. A Six Sigma Master Black Belt certification. has proved themselves to be an expert in taking a broad view of strategy across the company and coordinating teams for larger projects.
6. Champion: As an upper-level manager, a Six Sigma champion has a fuller grasp on the inner workings of Six Sigma processes and can lead LEAN strategy and deployment.

What Are the Roles of the Six Sigma Belts?

These are the various ways the Six Sigma belts interact with and support each other:

1. White belt: As the starting Six Sigma certification levels, white belts can begin learning more about the process by participating in company projects and problem-solving tasks at a basic level of quality management and waste reduction.
2. Yellow belt: A Lean Six Sigma Yellow belts participate in projects as a team member and increase their skills by reviewing potential process improvements alongside higher belt levels.
3. Green belt: After achieving their lean six sigma green belt training, professionals are ready to lead others and find more ways of using data to eliminate company waste. A green belt six sigma can lead teams of fellow green belts and assist black belt projects with data collection and process analysis.
4. Black belt: In addition to leading larger problem-solving projects, a black belt six sigma trains and coaches project teams.
5. Master black belt: A master black belt six sigma certification helps develop key metrics to shape their company’s strategic direction by acting as an internal consultant and technologist. Master black belts can also help train black belts and green belts.
6. Champion: Typically assisted by master black belts, six sigma champions focus on the organizational side of projects by tracking the progress of LEAN practice implementation and intervening when necessary. Executives can depend on Six Sigma champions to oversee processes in a way that removes defects, lowers waste and enables the company to succeed.

Can You Skip Belts in Six Sigma?

The Six Sigma belt levels are structured to indicate a professional’s understanding of the depth and scope of LEAN Six Sigma tools and their applications. If a worker demonstrates advanced knowledge of Six Sigma techniques and can successfully implement the solutions with applications on industry case studies, they may be approved to skip a level.

How Long Does It Take to Learn Six Sigma?

Because the Six Sigma career certification paths are self-paced, the timing of the program may vary. In general, earning a Six Sigma black belt certification takes a few months. However, those with previous Six Sigma experience may complete the program faster than others. Certification is based on a professional’s fundamental knowledge of Six Sigma procedures and is awarded whenever they pass the certification test.

Does Six Sigma Certification Increase Salary?

A Six Sigma certification demonstrates increased management skills, data understanding and leadership abilities, which ultimately qualifies professionals for a higher salary. Six Sigma black belts get paid an average of $127,000, which is nearly 34% more than Six Sigma green belts.

What’s the Difference Between LEAN and Six Sigma?

Although LEAN and Six Sigma share the same goal of instituting efficient processes and eliminating waste, they take different approaches to accomplishing it. LEAN concentrates on analyzing workflow to find ways of reducing cycle time and eliminating waste, while Six Sigma focuses on achieving consistent results. LEAN and Six Sigma can be combined to create LEAN Six Sigma levels, which take the best of both programs to improve a company’s processes from multiple angles.

Which Six Sigma Certification Is Most Recognized?

The most notable names in Six Sigma certification are the American Society for Quality (ASQ) and the International Association for Six Sigma Certification (IASSC). In general, the body of knowledge taught by both courses is nearly the same material. The main difference between the two programs is that the ASQ exam concludes with an open-book test, while IASSC administers a closed-book exam.

Although ASQ and IASSC are well-known national Six Sigma providers, many companies may benefit more from using a locally based Six Sigma program, such as MANTEC, which can tailor courses to manufacturing operations specific to the area.
