Companies hire IT departments to manage their IT infrastructure correctly. Maybe some companies just want some cheap kid who can activate a cell phone or plug wires into a tower, but those aren't the companies who NEED to care about IT. You go to your doctor and pay him good money so he can tell you how to properly take care of your body. If your doctor tells you that you have diabetes and you continue eating sugar, you will die. If your IT department tells you something is a bad idea there's a reason for it. You don't have to understand his logic, and he doesn't have to explain it to you. Your company pays him to understand all of that so you don't have too. Enterprise infrastructure is extremely complex and enterprise applications are often extremely fragile. If the company could exist without their contributions I'm sure there would be no IT department.
