It's a very big thing. Personally I have concerns about some of the socio-economic benefits that are put into some of these projects. My past experience with CF-18 procurement made me wonder. It is a good idea if it is exercised correctly, but you have to be very cautious that it isn't abused—in other words, if you have a socio-economic benefit, the price goes up and you don't get any benefit.
But openness is good.
I don't really have a lot of experience in big contracts of this sort. My typical contracts are in the range of $5,000 to $400,000.
