Arash provided a thorough and comprehensive introduction to the principles, ideologies and methodologies used in Lean Six Sigma. He was knowledgeable, engaged and showed patience in explaining these principles to the group. The course was a great introduction into Lean Six Sigma and has enticed me to further my learning for this subject. I would highly recommend Arash as a teacher of this subject with his skill, passion and knowledge for this subject being world class. I look forward to developing my skills to higher levels of Six Sigma in the future with Arash.

We contracted CBIS to assist us with design and implementation of our quality, safety and environmental management systems in compliance with ISO 9001:2015, ISO 14001:2015, AS 4801:2001 and applicable legal, statutory and contractual obligations.

As a first-timer I entered the process with some trepidation, but Arash and his associates were both thoroughly professional, and friendly and accommodating. What I expected to be a painful process was ultimately quite straightforward and very effective.

I am appreciative of the efforts of CBIS and would have no hesitation recommending their services to any company seeking compliance auditing or similar services.

With kind regards

General Manager- Emotivate Pty Ltd

We appointed Dr. Arash Niavarani of Comprehensive Business Improvement Solutions (CBIS) in June 2013. We retained the services of Arash for a 12 month business improvement project during which he trained and coached 20 of our internal managers as Lean Six Sigma Black Belts. From the very outset, we were hopeful that the CBIS investment would provide spin off benefits in addition to the training program. We have not been disappointed.

As a result of the CBIS training and coaching package, several business improvement projects have been identified within my business unit and my team is practically applying their newly gained knowledge under the supervision of Arash. The supervisory aspect of the engagement has enabled us to unlock greater value than simply a return on the base cost of the project. The guidance provided by him has not only improved my team’s skills and knowledge, but we have also managed to positively influence multiple coworkers in each project which has led to a significant number of people being more effective, efficient and productive.

We were extremely impressed by Arash’s professional, yet friendly and flexible manner. He explained the different topics in simple, easy to understand language and his practical approach has helped us to apply the tools and methodologies easily.

In summary, I would like to thank CBIS and Arash for their professional approach to our learning situation and would not hesitate to recommend their expertise to any business who is serious about improving their internal processes.

We are satisfied with CBS service and do not hesitate to suggest them for professional training services on quality tools such as MSA,SPC, FMEA, APQP, PPAP, DOE, Process audit (VDA 6.3),Product audit (VDA 6.5), ISO/TS 16949 and Lean six sigma.

I met Arash, director of CBIS, in May 2013 when he was contracted to conduct an environmental triennial audit and a safety surveillance audit for Donhad Pty Ltd.

Arash is a well presented professional who is highly knowledgeable in continuous improvement, six sigma, root cause analysis, problem solving, “Quality, Safety and Environmental Management Systems” and systems auditing.
It was a pleasure working with Arash and his team at CBIS. I recommend CBIS services for any of the doctrines listed above. Do not hesitate to contact me if you have any further questions.

Arash is a highly talented trainer, mentor and coach in the areas of Lean Six Sigma, Quality Management & Certifications. His expertise and command on the subject is second to none. I have been highly privileged to attend a black belt course in Lean Six Sigma as his student. Our entire group have been highly impressed with the seamless delivery of training. He goes over and beyond to ensure that his students not only understand the concepts but also practice in work places. Very confidently, I can say that he is one of the best trainer ever seen by me. I would be pleased to recommend him as a trainer to any organisation who would like to gain knowledge in the areas of Quality Management, Process Management & Continuous Improvement.

Its an honour to provide a written recommendation for Arash, the director of CBIS. In this instance, the quality and detailed knowledge of the Lean and Six Sigma from him was exemplary – what impressed me most of all, he was able to simplify and explain very complex statistical methods in away that elementary students such as myself could understand. He was always enthusiastic and willing to transfer his knowledge and go over material again until we had understood the concept.

I would like to thank Arash for his efforts and have no hesitation in recommending him for any Lean Six Sigma training and also his ability to provide guidance and leadership as a Master Black Belt Project Manager.

Laurie Kennedy

As the Six Sigma Master Black Belt, Arash has certainly provided the direction and motivation to continue and complete my training. Arash has an understanding of each participant’s projects and respects that each of them have varying degrees of experience and time availability. I have no hesitation in recommending Arash for leading and facilitating any Lean Six Sigma project

Arash is an extremely knowledgeable process control specialist. His practical application of Lean 6 Sigma doctrine has made a substantial and substantive difference to our operations, improving flow and productivity. I look forward to any opportunity to work with him again in the future.
