Excellent course work. Instructor in the video is great - great examples, extemporaneous, authentic - really, really good. The entire set up is fantastic so you can work at your own pace based on your background knowledge and (for Black Belt primarily) math and statistics aptitude. The real life, timely examples were the best. I am applying it on the job already. I highly recommend these courses and format. I learned a lot and already have new products and services in mind that I know I can create in our consulting firm.
