Lean Six Sigma Green Belt on a Limited Budget
I used Lean Six Sigma Training Ltd to obtain the Lean Six Sigma Green Belt via their online programme. The online programme is excellent in terms of resources/learning materials backed up with great customer service from John and his team with very quick response to any queries that I had in relation to the online programme.
If like me you’re looking to get your LSSGB on a limited budget then Lean Six Sigma Training Ltd is the company you should contact in the first instance.
Looking forward to doing the Lean Six Sigma Black Belt later this year with Lean Six Sigma Training Ltd.
Knowledge is power
Knowledge is power. To acquire knowledge, one must study, but to acquire wisdom, one must observe.” My observations on how I bagged the agreen belt certificate through the IASSC Institute experts, was just amazing. The download and the breakdown of the subject matters were very simple, correct, and interesting.
If one has knowledge, let others light their candles in it, The IASSC Institute have allowed me, and so many other hardworking students, to bag their well deserved and rewarding green belt certificates, and allowing, so many to fly in colours. From the modern teaching infracstructures, conducive Environment, to the qualified experts lectures, was such remarkable. My great experience with the IASSC Institute in Zurich can not be eradicated from my medula by any known Arabian perfume. It is beyond a doubt that all our knowledge begins with experience. My experience with the IASSC Institute in zurich was very amazing, and I hereby commend.
Knowledge rests not upon truth alone, but upon error also, but this error is what I could not for now think of.
Quality course materials
Quality course materials - very easy to follow and great support from the Lean Six Sigma Training Team.
I really enjoyed the sessions
I really enjoyed the sessions, simplified the complexities and made me focus and formulate my thoughts to the right developments.
One thing was limiting is other candidate perceptions and competitiveness, it worked both ways +ve and -ve, but the glass is half full and I have to work on it.
Overall I really recommend this course and trainers inputs and they made it look easy yet professional.
I highly recommend John Dennies and Adam Bowden as trainers also recommend the certification IASSC and Lean Six Sigma Training Ltd.
As self-funded BB Trainee, this training had the right balance in comparison to competitors, it makes individuals work for their certification yet not to be intimidated by the skill demand. The training Simple Made Perfect
John was really great
John was really great. Nothing to say more here. A mentor and teacher like him is really good and having the right focus on the course is even better. I passed the Black Belt because of his focus
Green Belt Training
An excellent introduction to Six Sigma. John used excellent training techniques in the classes and explained the principals of Six Sigma in clear understandable English.
I will now be able confidently put in to practice what was taught.
