I'll tell you how you do it. In this modern world of computers, you have a category for everything right down to replacing the screw that came loose on that hinge. In today's modern technology, sir, it is possible, and if you have a category where you cannot define it, you have the category called “undefined”. You put it in that category, and you ask the person who's executing to describe what it is they did, because they cannot find a category for it.
I'm illustrating for you the fact that in a modern database tracking system, a cost tracking system.... We're not talking here about estimating what the costs will be. We're not talking about that.
