Sure. That's an excellent question.
Our analysis, as you saw from our report, took into consideration three factors. One was strategic fit to requirement: what is the requirement of the Government of Canada? That is well documented. As well, what are the risks to implementing this and to sustaining the future state, as well as the costs and benefits of doing it? We took all three of those into consideration when analyzing the different service delivery options, which included status quo, complete outsourcing, or doing it all in-house--moving it all into complete shared services--as well as a couple of options that are combinations of internal service delivery and external service delivery or private sector delivery.
The reasons we landed on what we call the centralized moderate scenario, and why we think that's better than a complete internal service delivery or complete external service delivery, are twofold. One is that there are many aspects of infrastructure delivery in the Government of Canada today that are best in class. We believe some functions are being run very well. An example--and it's a point-in-time analysis, but in the mainframe area--is that the Government of Canada is ranked very well against our benchmark data, so we believe this kind of function should remain in-house but should potentially be centralized, because if one department is doing that well, the actual knowledge and expertise should be spread to other departments that are potentially smaller and can reap the benefits of it.
Conversely, there are many functions the private sector does well, which are, as I mentioned earlier, functions that are being commoditized in the marketplace today. Doing so is becoming almost a utility. As a result, we think that blending of best-in-class internal capability with private sector external capabilities in a moderate fashion is a very sanguine approach to this process.
The other thing is that from a risk perspective, moving to a complete in-source or complete outsource scenario presents the highest risk to transition. I think a moderate approach--i.e., a blended approach--has a lower risk for implementation.
