 There are a lot of factors that are really forcing companies to make a change in their supply chains. Of course we know about the regulation that's existing around the world in different ways. There's, for example, GDPR is a privacy regulation coming out of Europe and there's similar ones in the U.S. and other places. We know there are trade wars going on, so agility and flexibility and be able to move your supply chain to different places to get lowest cost and best value, really critical. But the single biggest change that's happened is not actually technology. Everybody knows about technology and AI, machine learning, how fabulous that is now can really change the way things work. What people really need to think about is the new customer. In fact, the customer today is far different than the customer that existed five years ago. In fact, the customer today, they want something not tomorrow, but today. They expect immediate fulfillment. They want something that happens to fill their needs specifically, market of one. Five years ago we didn't have this level of competition, this level of finding things that make the customer happy. So there's a series of things that define a new customer. The new supply chain needs to manage that and a digital supply chain can make that happen.
