In many businesses with lots of heavy machinery or other forms of OT, CIOs and IT departments will often be closely involved because of the critical role of all that technology, de facto technological convergence and integration (with the network being a first driver when many of these industrial assets started being seen as less stand alone than before) and the ways OT is being looked upon from the same view as IT in regards with, for instance, security.
Still, in some areas the distinction is clear. You won’t quickly see an IT worker repair a high-tech oil drill and, the other way around, you won’t see an engineer who takes care of the technologies to assemble cars, sit in a meeting on using predictive analytics to protect the corporate network from cyberthreats. But, as said, the lines between both do blur and the Internet of Things is no stranger to that evolution.
