While consumers are aware of how technology is delivering the world to their fingertips in a very literal way by bringing news, communication, and shopping options directly to their phones, they aren’t always aware of the ways in which technology is changing the way the products they use are made.The possibilities inherent in linking the capabilities of digitalization to the physical aspects of industry by capitalizing on the growing abilities of the Internet of Things (IoT) and other technologies has earned a name of its own, Industry 4.
