Basically, I think it's when they can pass the test of a value-for-money audit. If it shows that there are significant savings over doing this in-house or through the public service, then I think they should be considered.
As I said, it's also if they don't contravene any of the areas that I specified earlier. In particular, if it's sole-sourced, under no circumstances should we ever get into that again. That's your job, and that's where councillors come in, and the provinces have to regulate these things. We know they need a degree of commercial confidentiality, but there has to be good governance around them or the public won't accept them.
