Ok, so this one I actually kind of agree with. Too many times I was in a position where a bunch of decisions were made about software or hardware, and then IT was brought in at the last minute to try and get it all to work in an unreasonable time frame. And then IT was asked it integrate it in impossible ways.
If another department brings IT in early, different story. I got in to IT to use technology to make people's lives easier, not to play with whatever the latest fad bullshit is or develop an inflated sense of self-worth. If some random nobody's software is going to do that at the cost of a minor annoyance to me, that's fine.
