Industry 4.0 is the confluence of disruptive digital technologies that together carry the potential to change the manufacturing sector beyond recognition. The movement has gained critical momentum as a number of factors have come together: an astonishing rise in data volume, computing power, and connectivity; the emergence of advanced data-analytics and business-intelligence capabilities; new forms of human-machine interaction, such as touch interfaces and augmented-reality systems; and improvements in how digital outcomes are transferred to the physical world—for instance, through advanced robotics and 3-D printing.
