I think it's something we want to work on with our staff on to make sure they have the tools to perform that challenge function.
Also, one of the initiatives we're continuing to implement is e-procurement solutions. In the past, what was happening was that you could have all sorts of documents being filed in different ways. You could have CDs, hard copies of documents or emails. Over the last few years, we've been deploying a new e-procurement solution that will basically document all of the interactions that contracting may have with suppliers and clients. That will go a long way toward addressing some of the issues of the variations in terms of the lack of records.
The documentation of all the questions being asked as part of the same electronic platform is something that we're pushing. I have to say that in close to $6 billion of contracts, we're basically using that platform. We've made great progress over the last few years on that front.
