IT projects past a certain size get quite complex. They have a lot of moving parts and often those parts have to be aligned correctly and at the right time to make everything work. In turn, that means you need the various people to pull together to make sure the project as a whole delivers. Sometimes the team doesn’t succeed but normally everyone is pulling in the same direction. There is no “I” in team! Etc Etc
There are exceptions. In one place I worked the IT departments were actively trying to push each other under a bus. Think ‘Game Of Thrones’ with RAID arrays.
In the IT department where I first worked, there was a Network Admin who was a bit ‘highly strung’. He’d get quite short when things got tense and he liked things done the way things were always done (he supported the physical network and Novell; this was in the time when Microsoft NT was just starting to make inroads into business).
