It is very interesting reading about pre-internet-times. My first memories regarding computers date back to the early Nineties when my father bought our first PC, an IBM.....and at school, we had a voluntary weekly lesson in informatics where we learned to write small programms in Turbo Pascal....

Lavinia, I am also old enough to remember those days. In fact, I worked on one such network, General Electric Information Sercices (GEIS). Back then they were called service bureaus. They also had their own world wide packet switching networks.
The question I have is when will the balance tip, as it did for service bureaus. The real reasons they existed, by the way, was the expense of the computing platform (the mainframe). They died off (mostly) when computing could be bought in smaller units (the minicomputer and workstation).
On the network side, many companies had their own worldwide networks, often based in DECnet (remember DEC?). Given the issues with the NSA and hackers, it will be interesting to see how that aspect evolves.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
While people may talk about the procurement process, the procurement discipline actually encompasses a number of different processes. They include spend analysis, supplier relationship management, and contract management, just to name a few.
