That's an excellent question in the sense that we have had to really take a step back and look at it from a project management perspective. We've spoken here about the requirements and the timing. You made reference, earlier, to the U.S. investments and our own investments of $5 billion, so we really have to take a risk-based approach to what we can do to accelerate it, to reduce the complexity of the business requirements and to streamline the various procurement negotiation steps that are there.
Perhaps from there Mr. Page can give some examples.
