For manufacturers, the transition to Industry 4.0 has meant the accumulation of data, massive data. Indeed, the accumulation, distribution and evaluation of data are driving virtually every decision on the manufacturing plant floor and supply chains shaping those decisions. Given the striking fact that ninety percent of the data in the world has been created over the last two years, it isnít surprising that more than 60 percent of large companies report having a Chief Data Officer. But what has opened the floodgates to this deluge of information in manufacturing? Ordinary sensors have been transformed into smart sensors with the advent of IoT technologies and are being deployed by manufacturers along every step of the supply chain. Sensors are now detecting everything from when a piece of equipment will need maintenance to controlling energy costs inside factories.
