I might just add to what Liseanne mentioned earlier. I'd gone through a similar exercise in the private sector. One of the conclusions as we approached the end of approximately six years of very much the same type of work was that as we went through the work—we didn't know this would be the result—things became much less complex.
Today, if you think about what you had under the old regime, you had 500 data centres delivering information to people located in 3,000 places across some 62 networks, etc. There was an unbelievable complexity to try to understand and then to manage all that. When you think of it, an end-of-day model essentially says, hang on, we'll connect those 5,000 people across one global network to five data centres that are properly constructed to withstand all kinds of peril and are resilient both for security and from the perspective of being able to withstand any number of different perils. It's a much simpler place to run and operate, thereby enabling much more. It's easier to do work in a world like that.
The issue is that you have to persevere. You have to realize there are going to be bumps in the road. On top of that, unforeseen things are going to happen to you, because it is over a period of time in an area that in fact can be quite turbulent. There are always things that happen and, nine times out of ten, IT is involved. You just have to persevere and stick with it.
