I'll just speak to the first part of your question.
Some of the changes—indeed, all contract task authorizations—come through a senior executive committee now to conduct a challenge function, and we've centralized all procurement into one branch. What I saw was a breakdown of roles and responsibilities. I saw engagements with contractors without seeing the presence of procurement officials. Procurement officials play an important role beyond signing documents.
Based on what I saw, I felt there was a breakdown and a lack of controls, and that's what I've put in place.
There will be more recommendations to come. We'll calibrate. Perhaps I'll be found to have overreacted and slowed things down, but right now, given what I've seen, that's what I've put in place. At the same time, I'm trying to use fewer contractors.
