I have been involved in Lean and Six Sigma processes and tools in many different projects and positions but had never gotten certified. A Black Belt suggested your website for formal training and certification. I found the training to be well designed, thorough and easy to follow and understand. A good many Six Sigma training programs almost seem to try to confuse in order to impress. Your training used real world exercises, problems and solutions to easily understand the principles and tools available. Great job! I highly recommend your website and training process.
