What is Six Sigma?

Six Sigma is a system and methodology for process improvement that focuses on eliminating problems and defects in product or service quality. Process changes are based on the results of data analysis and seek to achieve measurable quality and financial improvements.

Six Sigma provides professionals with a structured problem-solving framework, statistical tools, and techniques to drive continuous improvement in organizations. Certification levels use martial arts terminology, and each has a defined role within an organization. For example, Six Sigma Yellow Belt Certification indicates that someone is new to the world of Six Sigma and has a minimal role, interest, or need to develop foundational knowledge, while Six Sigma Black Belt Certification indicates that someone is qualified to lead individual Six Sigma project execution.

How to get started in Six Sigma

1. Familiarize yourself with the Six Sigma framework

The Six Sigma framework uses a core paradigm known as the DMAIC process. This acronym stands for define, measure, analyze, improve, and control. It forms the basis of the Six Sigma quality management system.

Begin by exploring the Define, Measure, Analyze, Improve, and Control (DMAIC) process and its underlying principles. A Six Sigma course is the ideal way to get started, but you can also pursue self-guided learning.

2. Target an initial Six Sigma certification

Six Sigma certifications operate across multiple levels, beginning with the White Belt credential. A Six Sigma White Belt is the ideal certification to target as a beginner.

To earn your White Belt, you'll need to pass a series of shorter tests or a single comprehensive examination. Both paths require a strong working knowledge of foundational Six Sigma concepts, which you can gain through structured programs or independent study.

3. Apply your Six Sigma skills

Next, apply your developing Six Sigma insights in professional contexts.

If your current employer or position doesn't require employees to develop Six Sigma skills, take the initiative on your own. Talk to your supervisors about the value of Six Sigma processes, how they might help, and how you could implement them in your organization.

4. Upgrade your knowledge

The Six Sigma methodology is designed to promote continuous learning and ongoing professional development. Build on your existing knowledge by taking increasingly advanced Six Sigma courses or structured learning programs, or by following a self-guided curriculum.

The Council for Six Sigma Certification offers an extensive library of free training resources.

5. Pursue higher-level certifications

Beyond your Six Sigma White Belt, you can also earn Yellow, Green, Black, and Master Black Belts. If it serves your interests and professional goals, you can repeat this process at each successive level until you reach the highest level of achievement you want.

How long does it take to master Six Sigma

To master Six Sigma, you'll need to reach at least the Green Belt level. Green Belts qualify for leadership roles on Six Sigma teams and have a direct path to expert credentials at the Black Belt and master Black Belt levels.

There's no firm timeline for how long this will take, but some training programs for upper levels of Six Sigma certification require multiple years of relevant experience. For example, the American Society for Quality requires Black Belt candidates to have three years of professional experience in a role that applies the Six Sigma framework.
