Is it a change or not? I can see both sides of the argument. After thirty minutes of arguing, it's still not clear that we know the definition of what a "change" should be. Was rebooting a server a change? Yes, because we don't want anyone rebooting servers willy-nilly, especially if it's running a critical service. How about turning off a server? Yes, for the same reason. How about turning on a server? No, we all thought. That is, until someone came up with the example of turning on a duplicate dhcp server, which screwed up the entire enterprise network for twenty-four hours. A half hour later, we finally write on the whiteboard: "a 'change' is any activity that is physical, logical, or virtual to applications, databases, operating systems, networks, or hardware that could impact services being delivered."
