There have been a number of changes. I think the largest one has been to move to a statement of requirements as opposed to a statement of work, which is basically defining the outcome the government is seeking as opposed to defining exactly how the work is done.
That has two benefits. The first one is that we allow the industry to find different ways of providing the work. It allows an organization that has a different way of performing the services to still meet our requirement without changing their business practices, and typically, in a request for proposal process, this would result in greater value for taxpayers.
