I’m in the United States Army in South Korea. If you work in the process improvement unit, you've no doubt heard of the Six Sigma Green Belt exam. Don't let this exam become an obstacle! I made it.
This examination can be completed with proper preparation. When I get out the US Army after I retire one day I see myself being a Warehouse Operations Manager.
This is a step toward my goal. Thank you Six Sigma Institute family for their service.

Great Course! Easy to follow and worth the time to take!

Great experience!

Thanks, Great Certification and Training!

Excellent

Excellent program from an exceptional institution

I usually will never leave reviews don't write reviews, unless it’s either really bad or really good. This was the really good! I had my black belt through my career path , but wanted to advance to the master level. The content provided is exceptionally geared toward success, and I found it both informative and engaging. Before this, I wasn't aware that a comprehensive book was available for studying Six Sigma, as many resources online offer only slide presentations, which can often be uninspiring and less effective for learning. This online book was a game changer, allowing me to revisit the material as needed. I am confident that, with the depth of information provided, you will successfully pass the exam as I did with the master black belt exam!!!! Thank you, Yeliz Obergfell, for making this resource available.

I must be honest, I don't usually give reviews, but this one got me in. I am a PHD student, and one of the reasons I want to take Six Sigma is because so many companies require it for leadership accountability. The content is purely for success. I enjoyed reading the content, and it has given me knowledge and insight to know more about Six Sigma. I did not even know there was a book to study for the sigma, since so many websites only provide you with their online prepared slide presentation which sometimes can be boring and unproductive to learning. This free copy online book made life so easier, I can always go back to review the book content before exam, and I am 100% sure that I will pass the exam considering the extent of information that is on the book. Thanks so much Yeliz Obergfell

Very satisfied by the certificate, I loved the fact that everything is easy to access and they even give you discounts on lot of learning packages that can be used anytime you want. Besides this certification is one the best known in the industry-

This is an excellent platform to get your Six Sigma certification. Thanks Yeliz Obergfell.

I highly recommend International Six Sigma Institute for anyone seeking a high-quality and inspiring learning experience.

You do deserve 5 Stars!

I have found this certification course is great for career ahead.

Excellent Course! Thank you.

I'am really bery happy learning from Six Sigma Institute, and which great success to everyone with the International Six Sigma Institute.

Amazing

Before commencing on my journey for a Six Sigma Black Belt Certification, I browsed through many sites, got in touch with many institutions and finally zeroed in on International Six Sigma Institute finding the first step ie an ebook on Six Sigma which everybody can download, read it and know what Six Sigma is all about. Its a detailed, more than a 500 page ebook which helps a first timer like me to understand the subject and make a decision. This book is free for all which helps people who are eager to learn but might be short of resources and....After a detailed study and in the meantime I kept on receiving regular updates and mailers in my Gmail account and the related offers. I responded to one of those mails from Yeliz Obergfell requesting for help on the pricing and immediately received a response with a link to register myself which I did and completed the assessment test with the result and the soft copy of the Certificate along with the badge which can be shared on your social media accounts.

The overall process with International Six Sigma Institute was so smooth, particularly the ebook which has its second edition now and you can read it thoroughly to understand the subject before taking the assessment and related certification.

I recommend everyone to read their ebook and make their Six Sigma Certification with the Six Sigma Institute, www.sixsigma-institute.org

Happy learning!

Excellent course!

Great information and its not rushed. You’re given your time to learn and take your exam.

Corso ben strutturato, argomenti chiari e coerenti

If you check on the internet, you will find 100s of sites offering sixsigma certification. And you wont find an option for cheap 100s & 1000s of $. The quality of training vary, but you wont be sure to invest huge capital. There is plenty of resources and videos available but certification is too expensive and you risk losing the money. The complexity of the assesment is almost the same. Another fact is that you are investing so much money with no assurance of ROI or jobs. This ISSI certificate assesment costs under $100 & their material is quite detailed to pass any BB assesment. However, dont stop at this material or this certificate, continue researching, pick projects, apply tools then you will get mileage of this value for money certificate. Internationl Six Sigma Institute is highly recommended!

Great Program

Super! I am obliged to you for your great work!

Thanks so much for give this opportunity to people like me !! Very easy way to get certified , very useful materials to get it done !! The way is presented is the best kept it up! I am going for my next step now Green Belt !!

Well written, informative, and easy to understand curriculum. I would definitely recommend to others trying to learn about the world of six sigma and to get certified.

I appreciate the fact that reading material was provided that can tremendously help you with your studies and you will always have access to it to refresh your memory. Great course!

This is a great organization that helped me invest in my career and future. It is very affordable, flexible and convenient! I definitely recommend them.

Excellent course for building your career with extensive knowledge.

Thanks to International Six Sigma Institute and Yeliz Obergfell for providing such an excellent course to be now capable enough to transit to industries/companies (Ph.D.'s/researchers like me). The course was excellent and able to learn a lot of ability to drive process thinking to identify and fix opportunities, define critical performance measures, and improve overall performance. I think I am now ready to swiftly shift/transit to industries.

I would like to say Thanks to six sigma institute for providing free training materials really helped me to pass the exam and learn new knowledge and update my skills

Excellent Training material and easy steps to complete the registration process and examination.

The entire plan, framework, superb training and certification program worth getting five stars.

Hi I am Akhter, Bangladeshi. I have been working in Vietnam as Engineering Manager for more than 3.5 years with renowned MNC. CSSBB makes me confident to apply DMAIC which is a step by step systematic mathematical approach. The practical problem converted to statistical problem, then apply DMAIC right tool(s) to analyze or Hypothesis test to decide reject or fail to reject H0, and finally statistical problem convert to practical solution. The book is helpfull, besides this Six Sigma Institute has a big panel from where can be get help while implementing Six Sigma approach to the workplace. I recommend the personnel who are especially related to manufacturing, can obtain the certificate and start add value to your organization.

Thank you!

The course material is great and I'm sure I'll refer to the text for future guidance as the need arises. The price was good compared to alternatives. The real value stems from the material, price and exam.

Great option for those seeking Six Sigma certification. I looked at different sites and companies for certification. This site offered an affordable route without the extreme sales pitch.

One of the best investments I've ever made is through signing up with this International Six Sigma & Scrum Institute! They are very professional, transparent, honest, knowledgeable and very helpful. As a working professional trying to advance in my career and equip myself with professional certifications that would position me in a competitive light, it was a pleasure working with Yeliz. The study materials, mentoring and 24/7 support made this experience very rewarding for me. I was able to pace myself through my studies, but have all my questions answered during the process making it easy and preparing me for exam time. Then the opportunity to take the exam up to 10 ten times was a big comforter & a great differentiator of these programs. I'm now a Certified Scrum Master & Certified Six Sigma Black Belt. Thank You !!!

Feeling proud...with International Six Sigma Institute

Six Sigma Institute offer excellent communication and support with Mrs. Yeliz Obergfell!

Great Programs!

I definitely recommend International Six Sigma Institute. I have 15 years working experience and some of them directly involved in quality and process improvement areas so I decided to formalize a certification by an examination of a worldwide-recognized organization so I choosed Six Sigma Institute. The study material is both extense and concrete at the same time. It was a quite hard study-time to get all the concepts reviewed and well conceptualized before taking the exams. Result was positive and I have to insist that effort always gives you a worthy recompense.

My experience with my CSSMBB program was top notch. The exam was very thought provoking and made me think throughly many of the questions on the exam. Having 15 years of Six Sigma experience, I appreciated the information provided to prepare me for my Certified Six Sigma Master Black Belt (CSSMBB) certification exam. To put the icing on the cake, the customer service I received from the staff was excellent as well! Highly recommended!

Six Sigma Institute is a very competent, helpful and proactive training and certification provider compared to other Educational Provider I have worked with so far.
I highly recommend them to anybody who seek to learn Six Sigma methodologies. The Study Guide is an excellent masterpiece and the book makes it easy to understand such a complex subject like Six Sigma.

Great experience, The material was very easy to understand and very well organized. I recommend you to get encouraged to do it. Many thanks and great work!

Six Sigma Institute shows the world how Six sigma training must be done! Thank you!

I liked the way International Six Sigma Institute welcomes and takes care of all persons who want to learn and grow in their careers!
In addition to that, Six Sigma Institute provides a very good price compared to other certification providers which even doesn’t offer a quarter of the value the Six Sigma Institute offers.
Great job and hats off for Six Sigma Institute!

Very informative and useful . Can't wait to apply my new knowledge I learned from Six Sigma Institute!

Fair and reasonable! Really enjoyed the class - our instructor provided common sense applications to some challenging coursework materials (statistics). Nice blend of theory and practical application!
About the right content for the class duration. Fabulous tools with Minitab and Companion.

Very well structure approach for SIX-SIGMA Green belt Methodologies. I recommend any researcher who has concerns about adopting TQM in his field, to go through Sigma Institute certifications.

Great website, great programs!

Thank you very much. I’m glad to get certification from Six Sigma Institute.

My experience with everyone from the Six Sigma Institute has been delightful. The excellent customer service set a foundation for a highly positive end user experience.

Thank you so much for enabling and empowering me to continue reaching forward to my dreams and goals.

SSI (International Six Sigma Institute) provides an effective and rewarding way of continuing professional development.

I took this course at MicroTrain, who partnered with the International Six Sigma Institute and used the institutes book "Six Sigma Revealed”.
Everything you need to know to learn and understand Six Sigma is indeed contained in this book.
It is clear, concise, and well thought out. I highly recommend it.

Very excited and happy that I had completed my Six sigma green belt from International Six Sigma Institute.
It’s been a year I had been planning to write the test. I cleared the exam in first attempt with 48/50 points. I really did not expect this would come out.
Thanks you so much once again for teaching me Six Sigma so well!

Hi there, I received enough material to obtain the yellow belt certification, a very good customer service and a complicated exam but it was a very good challenge, now I go ahead for the green belt.

Great Programs! Before attending exam, please make sure you have enough knowledge. Any certifications will have value only when you know how to apply in the industries.

Excellent

A little over a year ago, I was given a link by a United States Army colleague for the Six Sigma Institute. This link was sent to many of us in hopes that we would take advantage of the opportunity. I looked into the programs and found them extremely user-friendly and very practical.

As a result, I decided to start with the Certified Six Sigma Yellow Belt (CSSYB) and Certified Six Sigma Green Belt (CSSGB) certification programs. From there, I eventually completed the other certifications as well.

Several months ago, while attending a military course at Fort Knox, one of the main instructors took about 20 minutes to explain these programs to the students in the class. He had also achieved Six Sigma certifications.

The main instructor explained to the class that: After he completed his Certified Six Sigma Black Belt certification program from Six Sigma Institute, he received numerous job offers that include a prestigious position at Amazon Incorporation.

It is no secret that the United States Army utilizes Six Sigma Certification Programs from International Six Sigma Institute™ on a regular basis.

It is cost-effective and gets straight to the point. I often tout this program to peers, and I will continue to do so.

My experience with International Six sigma institute was the best when it came to get myself certified in master black belt and championship. Exams were conviniently placed considering participants at the centre, sufficient time was given as well as the ease of answering the options was exercised. Certification also was processed quite fast (immediately) thereby giving the participant full satisfaction.
Overall a very nice experience. I wish ISSI, Yeliz and her amazing team good luck ahead.

I learnt how to use all the process and quality improvement tools in a very clear and simple way. Your guidance brought significant efficiency increase to my business. Thanks to International Six Sigma Institute, by using all these tools I was able to create a much more motivating project environment for my team. Although my team members knew more or less about the tools before their study with Six Sigma Institute, they were not able to properly identify when to use which tool with clear roles and duties defined for the entire team.
Your outstanding Six Sigma training content helped myself and my team, and you gave us continuous support to understand Six Sigma Methodology. Most of my associates became certified for green belt and black belt, and some showed their passion for statistics and we began in-depth training sessions to empower them with knowledge.
Your program gave us a lot of self confidence and a noticeable pulse to start our new Six Sigma projects.

First of all I want to thank for your site that I learnt quite a lot. I think, your content is very complete and gave us enough support to comprehend Six Sigma Methodology. Nowadays I am implementing Six Sigma Methodology in my project, and thanks to your training program I quickly realized where I am doing good, where I can further improve. Your program contributed huge benefit to my knowhow and experience.

Wanted to thank your organization for providing this service!

As a consultancy & training enterprise, we have chosen International Six Sigma Institute to reinforce our own Six Sigma training programs. The strategy, of having such an excellent international partner like International Six Sigma Institute, has been proved as being the correct one to win more accounts and increase our customer satisfaction.

Overall, this is my best online certification experience so far!
The lifetime valid Six sigma Certifications from your Institute is really simple, easy and worth to its online registration, reading material and the test. The text and diagrams explain all aspects of Six Sigma very clearly leaving no room for doubts.
I got a thorough overview of the concepts which I'm rather sure of retaining (for lifetime!) and could relate to the real-projects well. As Consultants we have been doing projects along similar lines. The concepts tie these activities and roles into a Six Sigma Methodology that is more appreciated by the industry.
I wish International Six Sigma Institute many more such achievements in the future. Everything exceeded my expectations. I would definitely recommend International Six Sigma Institute to others who want to either complement their experience with certification or begin Six Sigma projects after certification.

Six Sigma is a highly efficient methodology to keep the teams always focused on the overall quality objectives and quality of project deliverables, and to drive the everyday tasks of quality management processes in line with the business objectives. International Six Sigma Institute assured us to have right and certified talents in our Six Sigma teams.

Thanks for such a great online Certification Program at a reasonable price! It wasn't easy to find a tailored Six Sigma Certification Program which lets me prove my professional experience and personal education in Six Sigma era.

Acquiring Certified Six Sigma Yellow Belt Certification has met and exceeded my expectations. I would have no hesitation to recommend International Six Sigma Institute’s Six Sigma Certification Programs to any other company or individual.

Although we called it "Six Sigma", our old process has been heavily customized for the working habits of my project leaders and subject matter experts. After having hired our new Six Sigma Experts certified from International Six Sigma Institute, we had an outstanding capacity to first start using Six Sigma methodology as it is and then iteratively customize and adapt it to our own business goals and needs.

I'm a finance and management professional with over 12 years work experience, based in Lagos, Nigeria. My career used to be plateaued in the last couple of years, so I decided to give it a boost by going to business school (which was a like "marathon") and then I needed a "sprint" - a qualification to give my career a quick boost - so I opted for the six sigma certification, and went in search of an online provider.
The value proposition of the International Six Sigma Institute is the most impressive among industry, so my wife has also taken the exam too. Registering for my exam was seamlessly easy, and the Six Sigma Revealed text has been very helpful. Overall this was an outstanding education and certification experience with Six Sigma Institute.

First of all I want to thank your organization for your efforts to provide a clear, understandable and yet free of charge book. And many thanks for your outstanding, quick and competent customer service department which enabled for me a delightful student journey with you guys.
During these days Six Sigma knowledge carries heavy credits in my professional achievements and thank you International Six Sigma Institute for teaching me key tools and techniques to accomplish my Six Sigma projects. Well done!

I completed my Six Sigma Master Black Belt certification. It was a great learning experience with Six Sigma Institute. It is a simple process to take admission, trustworthy brand, good and clear study material and most importantly the most cost effective certification in the entire Six Sigma Education market. I am happy with the entire process, which helped me achieve my career goals and also enhance my hands-on skills and knowhow.

I have taken the Scrum Master and Product Owner, Six-Sigma certification courses, and more recently the Project Management certification. I passed all the exams the first time, thanks to the awesome instructions and organized materials. I believe the quality of the course outline, greatly helped me to prepare for the type of questions on the exam. Certifications are a very good way of ensuring everyone reaches a common level of understanding. At the end of the day, it basically comes down to certifications being an internationally recognized credential. If you can put that on your resume, you'll have a competitive edge over another individual who doesn't have it. Thank you for preparing me for these exams and for your encouragement and support to succeed! I highly recommend taking your certification courses to anyone wishing to advance in the corporate ladder!

International Scrum Institute assisted me to gain valuable certifications in Agile Scrum. Their Project Management and Six Sigma offerings are also great. I also find their Testing Institute's curriculum to be valuable to my employees.
Scrum Institute and their affiliated entities really puts you in a different league.
