The schedule that is referred to was a very early schedule that we put together: How are we going to actually deploy this new solution?
We put an initial schedule together. That was almost two years ago. As we've worked through some of the risks and looked at the processes, we've continued to adjust the schedule, and we will continue to do so. If we learn after our initial few departments that we're going to need maybe a bit more time and that maybe we need to adjust the next wave of departments, we will do so.
Again, as Vidya was mentioning, it's a bit of an agile approach. I don't necessarily like using the word “agile”, but it's thinking of this as really iterative. As we learn, we will continue to adjust. I call the plan an evergreen plan. If something needs to change, we will make the changes. Maybe we can go faster. That's another alternative if things go well.
