Digital transformation enables industry to improve operational and business performance in ways never imagined before. To take advantage of the Industrial Internet of Things (IIoT), companies must expand connectivity across their people, assets, and systems, and make full use of extracted data to improve their operations and processes. All this connectivity closes the gap between IT and OT, meaning a company’s operations are in sync with their business, enabling greater performance.
