That's exactly it, Madam Chair.
There is a natural tension. Obviously, due to the age of the fleets, there is pressure to get ships sooner, and we all know why that is. We also want schedules that are credible. When finding that balance in the early days, the yards and the government, frankly—officials—were overly optimistic in terms of timelines.
As we now have a few ships under our belts, we are in a position to be more real in our challenge to the schedules. We're demanding more detail from the yards in terms of the schedules, so that we can assess if they're credible.
I have mentioned the earned value management approach that we plan on adding in, and we have started that. As the yards mature, we'll have a better sense of what they can deliver when, and we can change their schedules accordingly.
