Quite frankly, unfortunately, I don't think it's a concept that's susceptible to a simple, singular definition. The department's approach—and we document this approach—is to look at a broad spectrum of considerations and weigh those considerations.
As I mentioned, they deal with effectiveness and relevance. They deal with whether an alternative delivery mechanism to achieve the same objective would be better. They deal with the cost. We look at gender considerations and so on. We have a whole list of considerations, some of which are going to be more relevant in certain circumstances than others, but it's a question of identifying all of the relevant considerations that go towards efficiency and bringing forward an assessment of those to determine whether it's inefficient or not inefficient.
That's a continuum. You can't do a binary assessment of that because it just requires a complex analysis of a range of considerations.
