IT is becoming irrelevant as the workers increasingly rely on their own 'devices' and bring cloud services with them.
Business units specify and implement moves to cloud systems without involving IT, "who just get in the way and slow things down".
Sales gets Sales force, legal, HR, operations, finance all go to SAP, often as separate teams.
Developers code and deploy against AWS as IT cannot provide stable systems.
Legacy kit was virtualised and moved into the DC or a cloud provider years ago as IT could not
support the equipment.
End users all know their OS of choice and the applications they need to do their jobs, IT no longer
need to help out with Excel etc, the users are more expert nowadays.
IT may have to help out with HD swap outs and windows re-installs but thats getting to be the limit
of their involvement. Senior staff expense new high-end laptop purchases, IT only get
to specify laptops/desktops for low end staff, though often the finance team has the account
with a preferred supplier and just orders more of the same with hardly a thought about required use.
Phone systems are becoming virtualised and call routed to mobiles, no need for managing a phone switch and patching.
IT only need to provide network pipes/wifi, access to printers, service account creation (office365 etc).
