It really makes me cringe when people in IT or software development refer to those outside of those departments as 'the business'. It night seem innocuous, but there are certain things that this simple phrase implies.
1) IT and software development aren't part of the business, where the real work gets done.
2) it creates an us versus them culture.
3) if you refer to yourself as separate from the business, people will treat you that way.
It's amazing how a simple phrase can pack in so many meanings. Just remember that we are all part of the business.
