Again, our analysis had two aspects. There's a transformational part and a transitional part. In both cases, we believe that it's best practice to leverage the best expertise wherever it may be, whether in the private sector or in the public sector, to undertake those two transformational or transitional journeys.
With respect to the 54%, we actually looked at what we call towers or service bundles, and that's well documented in our report. They include things like mainframe operations or server operations, common infrastructure server operations, data centre facilities, and so forth. When we did the analysis of those requirements against the private sector capabilities, we found that the areas that the private sector can deliver well are being commoditized as a utility in the marketplace. When we did that analysis, we came to this 54% as being the amount of effort or the amount of work being done in this space that can be done by the private sector in the most efficient manner.
