I worked in the NHS during the initial £9bn "National Program for IT" (NPfIT) and the "Connecting for Health" and "SPINE" roll outs. I can tell you from my personal experience that very little of the money actually made it as far as engineers implementing and rolling out the systems. It vanished into management companies, agencies and well-connected people's pockets. Like water running through a series of leaky pipes. A hosepipe went in one end and a trickle came out of the other. I have never seen such corruption in my life as the Department of Health.
