Of course, when a patient registers with a practice I'm sure there's a nice central IT system that deregisters them with the previous practice, ensuring that only one of them gets paid.
.... ah! no, that was all too difficult, wasn't it? Sill, that was only £11bn down the pan. 
The procurement system is designed to be vetted by pen-pushers, who don't know what they buying and their guidelines tell them to accept the lowest bid. Companies therefore compete to put in the lowest possible plausible bid to get the contract. To keep hardware costs down they will specify inadequate hardware and too small a budget to develop the software and support systems. Hey Ho that doesn't matter they have got the contract, they have suckered the Government into
their system.

The contract goes ahead and the system is inadequate but that doesn't matter as they then go back to the Government, we have under estimated the hardware requirements, infrastructure costs, development complexity and costs blah, blah blah. Don't worry we have a solution (out comes proper plan what they know was really what was needed but would not be the cheapest to win the contact

) and they then tell the Government are you going to write off £11bn, or spend the further £4bn which they knew was required in the first place.

That is how the Government IT procurement system works, which is why virtually all public IT systems are not up to the job or fail. It is an absolute scandal.

The MOD has never been great at procurement, but it has got an order or two worse on the wasting of money since they privatized the MOD Procurement Executive as Quintiq as they no longer have in-house experts to vet proposals.
