★★★★★ Written by Sgt Brenton M. Kirk on October 8th, 2024

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.

★★★★★ Written by Mike Radcliffe on August 22nd, 2024

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.

★★★★★ Written by Roseline on August 14th, 2024

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

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!

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!

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.

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.

Its awesome finding out the International Six Sigma Institute and their outstanding support team who are always there to point you to your directions to a quick and easy road to achieving success as a Six Sigma professional.
More awesome is the Institute's free e-book, 'Six Sigma Revealed', an easy and simple to follow guide for all to passing the certification exams in few hours.
Nothing can be more exciting when you get maximum value and satisfaction for your money. With the Six Sigma Institute bottom rock fees and follow ups, I was able to earn my Green and Black belt Certifications in less than 72 hours. I have also just learnt something very important that: 'Specifications have their place, and only their place'
Remarkably, this is one of my best on-line certification experiences that is worth sharing with other professional colleagues and friends.

I want to thank you for your wonderful web portal. I’m very happy with the clarity and simplicity of your certification process. Your portal is user friendly with concrete and actionable information.
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.

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.

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.

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!
