Our take
Based on the ratings of 29,702 students, a sample of their written reviews and the syllabus, as the course stood in August 2026. No course pays to be reviewed.
This is a seven-hour, 85-lecture walk through the five DMAIC phases, taught by Six Sigma Academy Amsterdam, a group of Dutch university lecturers. Measure gets the most time at about two hours, then Analyze, with shorter blocks on Define, Improve and Control. Excel is the only software needed, and the White Belt course is recommended first. It has roughly 96,000 students and a Bestseller badge.
Reviewers like the plain English, the warm storytelling and the examples, and one says the quizzes help ideas stick. The complaints are consistent too. Some wanted more worked examples, especially from manufacturing and finance. Others found it too theoretical or too heavy on math, and one said the teaching assumes background knowledge instead of building a foundation. One reviewer calls it a good introduction but not enough for the exam, and another found the certification steps unclear. Still, about nine in ten of the roughly 29,700 ratings are four or five stars.
The content was refreshed in August 2026, so it feels current. The description itself admits Lean Six Sigma has no single agreed body of knowledge, so check that an SSAA certificate suits your employer before relying on it. As a fast, cheap overview that explains the tools clearly, it works well. For serious statistical depth or lots of practice questions, plan to add something else.
Pros
- Reviewers praise the warm storytelling and anecdotes that make dry tools easy to follow
- Covers all five DMAIC phases in about seven hours, with 11 quizzes to reinforce each stretch
- Optional free exam and credits through SSAA, run outside Udemy, for those who want more than a completion certificate
- Updated in August 2026, with about 90 percent of ratings at four or five stars
Cons
- Several reviewers want more worked examples, especially from manufacturing and finance
- One reviewer says it is not enough to prepare for the exam, and another found the certification process unclear
- Some students found it theory-heavy or too math-heavy, and one said it assumes prior knowledge
Great examples, warm and friendly storytelling, and thorough inputs all round
Listed for all levels, but one reviewer found it assumes background; the White Belt course is recommended first.

Course Description
CERTIFIED LEAN SIX SIGMA GREEN BELT
NOTE: At the end of this course, students will obtain a certificate of completion from Udemy. Students also have the option to apply for free, optional, extra Lean Six Sigma examination and certification + official credits. This external, free and optional examination/certification occurs outside the Udemy platform, requires registration (name, email and a link to your relevant Udemy certificate) and is offered by SSAA (Six Sigma Academy Amsterdam) which is an independent, academic-run training and certification institute with dual accreditation: (UK CPD and Dutch higher education BKO).
LEAN SIX SIGMA
Lean Six Sigma is not a new methodology. It actually has a history that goes back many decades. So what does Lean Six Sigma do? What is the aim? At this point we won’t go into too much detail, but the absolute essential goal of Lean Six Sigma is first of all to reduce waste or non-value adding activities. This saves costs. The second goal is to deliver quality goods or quality service that matches the norms as set by the organization. The aforementioned goals are goals that are relevant for every sector and for that reason we can state that Lean Six Sigma is beneficial in every single sector.
There is a hierarchy in Lean Six Sigma that is shown by belt colors. You start as a certified Lean Six Sigma white belt, then you progress to become a certified Lean Six Sigma yellow belt, after which you can continue to become a Lean Six Sigma green bet and a Lean Six Sigma black belt.
As you progress from certified Lean Six Sigma white belt to other belts, you gradually increase your Lean Six Sigma skills. These skills are very concrete and quite in demand in the job market. At this point, we do not ask you to take our word for it, but we invite you to actually do a bit of online research and find out for yourself.
Please note that unlike some other subjects, Lean Six Sigma does not have a universally agreed upon body of knowledge, or a universally agreed upon training and certification procedure. We are very open about this issue, because it should be known by every prospective Lean Six Sigma student. Make an informed decision by reviewing your (employer’s) Lean Six Sigma needs/expectations and compare that with what various Lean Six Sigma training institutes are offering in terms of training and certification and subsequently choose the training and certification that best meets those needs.

SIX SIGMA ACADEMY AMSTERDAM
Six Sigma academy Amsterdam (SSAA) is an initiative of an international group of university lecturers from Holland who have supervised projects at some of the largest organizations in and outside Holland. The aim was to teach what we already taught offline to university students and make that training more affordable, more accessible, more convenient, whilst making sure that it was practical, fun and easy to grasp. You do not need a particular set of mathematics or statistics skills to keep up. This Lean Six Sigma training is going to be very accessible for people from various educational backgrounds.
The Dutch BKO accreditation is an academic grade type of accreditation which differs from an accreditation that commercial parties offer to training institutes. This type of accreditation can only be obtained by academics. Although it is a Dutch accreditation, our experience shows that it is extremely well received outside Holland as well because of the academic nature.
SIX SIGMA, LEAN SIX SIGMA AND LEAN
Sometimes you hear six sigma, sometimes lean six sigma and sometimes lean. What's the story? Lean and Six Sigma are separate. Lean is primarily about reducing waste. Six Sigma is primarily about reducing defects. Lean Six Sigma is Six Sigma with Lean techniques and Lean tools incorporated in it. Lean Six Sigma does not incorporate the whole Lean philosophy in itself. Lean Six Sigma only borrows from Lean pragmatically. So Six Sigma is the pure Six Sigma methodology without Lean elements. Lean is a separate management philosophy and Lean Six Sigma borrows some Lean tools and techniques. Lean has no belts. Six Sigma and Lean Six Sigma do have belts to indicate level of mastery.

By Noushein Djavaheri on 7/10/2026
Overall, it is a good course. I would have liked to see more real-world examples from investment and financial companies. Additionally, it would be helpful if the course provided more in-depth explanations of the underlying theories, concepts, and formulas covered in the material.
By Vinayak Ashok Nikam on 7/7/2026
The Lean Six Sigma Green Belt course was clear, practical, and easy to follow. The instructor explained concepts well with useful examples, and the quizzes helped reinforce learning. Overall, it gave me confidence to apply Lean Six Sigma tools in real situations.
By Jerry Berkel on 7/2/2026
Very comfortable presentation and pronounciations of the material, short video's pointwise providing terminalogy with clear examples! And a good sense of humor to which makes it easy to follow!
By 湘薐 王 on 5/23/2026
I like the instructor's teaching style. Through the courses, I can have a good overview of how Lean Six Sigma works, and also how to apply it in real-life cases. It's also a good way to review the knowledge if you've learnt it in uni a while ago. Personally, it would be even better if you could provide more recent company cases. Thanks!
By Antonio Logan on 5/13/2026
Lots of good analytical information in the course. I know facts transcend time, but some of the data in the course seems dated. I'd update the videos with recent information for relevancy so students do not think they are receiving outdated instruction.
By Akula Ramanjaneyulu on 5/13/2026
This course is very well structured and easy to understand. The concepts of Lean six sigma are explained clearly with practical examples, making it suitable for both beginners and experienced professionals. The instructor's teaching style is engaging and informative. I gained valuable knowledge and confidence in applying Six Sigma methodologies in real- world scenarios. Highly recommended for anyone looking to improve and quality management skills.

As a Security Operations Manager (SOM), earning a Six Sigma Green Belt is a strategic power move. In high-stakes security environments, quality isn't just about aesthetics (like the Red Bull cans)—it's about reducing the probability
By Faisal Mami on 4/5/2026
Video quality and clarity are good. Shouldn't need to be said but the certification here means nothing. Sometimes takes too long to get to the meat and potatoes of the topic. Jump between complexity of Green belt to Black belt is pretty high so I would've liked to go into more details in the Green belt class. Explanations are clear but again could go more into the statistics. The lean topics covered are pretty minimal.
By James Aso on 2/24/2026
This course was very indepth and the lecturers are really industry professional with very skillful teaching skills that motivates you to believe you can be the best LSSGB professional you can be. I also wish Minitab will be included but the course was aptly taught.
By Yuri Marques dos Santos on 11/15/2020
