Obviously, we are very conscious of lessons learned associated with other systems development. The approach we've taken to develop prototypes is a way for us to ensure that before we go to the market and start procuring this solution, we will have tested it through prototypes. This will allow us to focus the scope of the system project and to a certain extent redo some of the risks associated with that. That's the approach we've taken.
I think we may have a little presentation we could send your way that will describe a little bit what we're doing.
