“I have worked with VRI for over five years, beginning with training, which eventually led to my Black Belt in Lean Six Sigma. The work that VRI does adds value, as they help us to better understand how to utilize LSS within aspects of the oil business, human resources, and education. They truly provide a practical approach to LSS with great customer service and council. I highly recommend them!”

“VRI has supported our Lean Sigma program through on-site training and mentoring since we started our first program in 2000. They understand oil field processes and are able to effectively integrate examples from our company into their training material.”

“The Lean Six Sigma training I received from VRI exceeded my expectations. The instructors are extremely knowledgeable and connect well with the class. I particularly enjoyed the real-life examples from the instructor’s own consulting experiences. The training is a total immersion in Lean Six Sigma methodology and is a fast-paced and interesting learning process. Thanks to VRI’s highly effective training, I mastered all the tools and techniques of a Black Belt at the program’s end. More importantly, I believe that I speak for all the other class participants, as they too achieved a similar level of knowledge and training excellence.”

“The ease with which the complex concepts are explained makes the application very easy and has resulted in numerous benefits in our manufacturing and transactional processes. The practical examples in the instructions not only help introduce new ideas for making improvements in the business but also illustrate the do’s and don’ts of the application.”

“VRI’s Lean Sigma training uses the right combination of good textbooks and training materials, great instructors, and fun learning sessions. In addition, the instructor, having an in-depth knowledge of their industry (e.g., Oil and Gas), provides regular mentoring sessions with class participants to deliver projects, improving a company’s bottom line significantly.”

“VRI has helped provide Dreyer’s with top-tier street fighting knowledge, which we have been able to apply immediately toward variance reduction in our systems and processes. I have yet to find a chartered activity for which we could utilize the tools. Not only did VRI’s training teach us how to work through a project from beginning to end, but we also learned how to choose the right tool for the job!”
