I witnessed the outsourcing of 3000 IT in a large company in the mid 2000. The contract was great for the outsourcing company and signed off by a bunch of bozos who had no idea how IT runs.
The idea was to have tickets for everything and "golden" ones vichy cost a fortune but are super high priority.
IT was mad at being outsourced and played the game. "super important" thing coming? Ticket. "just a cable, man"? Ticket.
What the idiots in management discovered, is how THEIR company actually works. How important the human relationship is.
One of my colleagues in IT had the pleasure to tell a board member who came to be serviced right oway to fuck off (his words) and to open a ticket, if he knows what this is
Then he picked up the phone as someone was calling and turned away.
