What is Lean Six Sigma?

Lean Six Sigma is a methodology that creates projects or team efforts to improve performance and decrease defects, costs and waste. It’s the combination of lean manufacturing (quality control by reducing waste and continuous improvement) and Six Sigma (set of techniques and tools for process improvement).

Lean Six Sigma Belts

The Six Sigma Belts follow an order of responsibility to the project and how much knowledge they have:

  • Six Sigma White Belt is the most basic certification. They engage with local teams that assist projects and are not directly involved.
  • Six Sigma Yellow Belt holders are specialists that support project teams on problem-solving tasks in the project.
  • Six Sigma Green Belt holders understand advanced analysis and can resolve problems that affect quality. They lead projects and assist black belts with data collection and analysis.
  • Six Sigma Black Belts are experts and agents of change. They provide training and lead projects.
  • Six Sigma Master Black Belt is the highest level. They will shape strategy, develop key metrics, act as a consultant, and coach black and green belts.

According to Salary.com an average income for a Six Sigma Green Belt holder is $110,800 in the United States.

Lean Six Sigma Professional Certification vs University Certification

In order to receive a professional certification, you need to take an exam from a recognized institution. There are purely professional certifications from independent entities and there are university level certifications; they are both valid options for most of the industries. However, you should always check with your employer and peers what is the most adequate certification for your needs. The most internationally recognized certifications are provided by ASQ and IASSC. Therefore, when studying Lean Six Sigma courses, always focus on picking courses that align with those exams. Also, different certifications will have different requirements, for example: ASQ Green Belt Certification requires 3 years of professional experience in a Six Sigma project while IASSC doesn’t require any previous experience to take the exam.

Best Courses Guides Methodology

I built this ranking following the now tried-and-tested methodology used in previous Best Courses Guides (you can find them all here). It involves a three-step process:

  1. Research: I started by leveraging Class Central’s database with 100K online courses and 200K+ reviews. Then, I made a preliminary selection of Six Sigma courses by rating, reviews, and bookmarks.
  2. Evaluate: I read through reviews on Class Central, Reddit, and course providers to understand what other learners thought about each course and combined it with my own experience as a learner.
  3. Select: Well-made courses were picked if they presented valuable and engaging content and they have to fit in a set of criteria and be ranked accordingly: comprehensive curriculum, affordability, release date, ratings and enrollments.

Course Ranking Statistics

Here are some aggregate stats about the ranking:

  • All courses accrue over 1.8M students.
  • Three courses offer free Six Sigma White Belt Certification.
  • 6 courses are free or free-to-audit, 4 courses are paid.
  • 4.8K students follow Class Central’s Six Sigma topic.
