When there is a problem with the network, time matters. We need to be able to quickly move from device to device in order to identify and rectify the problem. In order for this to occur, we have to know where to go to next, and how to get there.
Let me give you a scenario. You are having some problems on the network that are spread across several devices. You go into the log file of each device and see a bunch of messages with a mix-match of various times that mean absolutely nothing to you. In short, you have no idea what is going on with your network.
Do you have everyone that you need (or would like) to complete your mission? If you are like pretty much everyone in the Army, the answer to that question is no. Rarely does a unit have everyone assigned to it that they are authorized and even in the case that they do, you still have people pulling guard, on profile, or whatever. The short answer is that we never have enough people to take care of all of the tasks that need to be completed which is why it is critical that we effectively manage how we use our personnel.
