I think, perhaps, what I want to start with is just the why life-cycle costing, for example, is important. When you're dealing with this type of equipment, and we've heard about the complexity, we've heard about how much the equipment costs, how long the equipment's going to last, how many people are needed to support it, how many people are needed to operate it, all of the costs, fuel and other things that go into operating it, maintaining inventories, it's extremely complex. So whenever a significant piece of equipment is being purchased, that significant piece of equipment can have a significant impact on the budget of the department for many years to come.
The idea about life-cycle costing isn't about trying to tell departments they need to be able to figure out how much a replacement bolt is going to cost 25 years from now. It's about telling departments that they need to make sure they're doing a good job of understanding, when they buy a piece of equipment, what the impact of that will be going forward.
I think here, one of the things that we particularly identified—and I think this is a common issue in other large projects—goes back to the assumptions. One of the assumptions that we highlighted and has been talked about today a number of times is the assumption that the cost to maintain and support the new equipment would be no more than the cost to maintain and support the old equipment.
At the time, and I think one of the things that bothers me a bit about today is that the people who made the decisions and the people who made the responses to us in 2011 are not the people who are here today who are having to try to defend why the department said they would get some of these things fixed by now and they haven't gotten them fixed.
When you go back to some of these decisions, that the support cost for new equipment would be the same or less than the previous equipment—and I think I said it in my opening statement—that just was not a realistic assumption. It's important for these assumptions to be realistic so that the departments understand, when they're buying a significantly complex piece of equipment, that it may significantly change how many people you have supporting it, how many technicians there need to be, what the operations are even in terms of military personnel for the new pieces of equipment, because it's going to be different. Starting with an assumption, for example, that it's not going to be different, quite frankly, isn't a realistic assumption.
I think two things to draw from this are the importance of life-cycle costing, not down to the nuts-and-bolts issue but from the point of view of how it will impact long term, and in what pattern, the budget of the department; and the importance of having good planning assumptions that are realistic, to help you understand what that impact is going to be.
