On the least expensive opportunity assessments, yes, basically you want to look for the value and not the cost of the audit. In the cheapest audit you cannot find new opportunities. You can only recommend what you've always recommended before. You can't measure anything.
You actually want to buy that value, because that gives you the right answer later on. When you do that, your average payback is under one year. You want to design the programs...and it's any of them, whether it be food or water. We do them all at the same time, because it's much more efficient. We're in the plant. It's minute by minute. We measure everything. We get the opportunities. You want to have that step of what you should do versus how to get this done. When you get to how it's done, if it's the right thing, then you don't even need help to do it. If it's the wrong thing, you need a lot of expensive help to put that in.
