The best testimonial was when I was the new VP Quality, Device Engineering (2012) for a medical device manufacturer and we had a surprise inspection from the US FDA. This company was in a real regulatory pickle. The investigator started claiming that we had a serious issue with a particular component. The production people were completely flummoxed. While sitting in the front room while this rant was occurring I downloaded the hard production data and, real time, I analyzed the data to show that there was, in fact, a bi-modal distribution, not a fault condition as described by the FDA. Paid for itself and many additional licenses right away.
