Again, the situation in the U.K. is very different from that in the U.S., because the volume of law that Dr. Ross has referred to doesn't exist in the U.K. There is a lot of guidance and a little bit of law about procurement.
Processes are there for two reasons. One is to make sure you're buying just the right thing and the right priority with the money. The other is to make sure the behaviour of the parties involved isn't improper in any way. Those are risks that are well recognized, but what's less well recognized is that if you take these through sequentially, if you have a very measured system, you have other risks, which are that your equipment doesn't arrive in time or it's out of date with the things we're familiar with.
I would quickly observe that in many aspects of life, and certainly in defence acquisition, trust among the people who are doing the work—trust in their judgment and in their integrity—saves a lot of work and a lot of time, but it's a fairly scarce thing in government and something that public procurement officials are reluctant to rely on.
