The UK government doesn't care about shit IT.
Shit IT brings more bums on seats.
If we made 20,000 NHS jobs redundant tomorrow due to some super software, the government wouldn't implement it, because that's 20,000 people unemployed, and voting against them. As can be seen by the unemployment whining since Cleggaron got in, (more women than men in the public sector unemployed,) it goes out of its way to generate sort of non jobs for single mothers, women with arts degrees, and so on. This is its job. If it didn't do this, and the boiler failed, would you call a diversity officer? No. So they have to make jobs for people who can't do anything.
It would rather waste 10 Billion on a five year job which fails, one day after re-election, than make four major league techies, millionaires for delivering it for one hundredth of the price, in 6 weeks.
Politicians win popularity contests. They don't win IQ tests, honesty competitions, the Miriam Stoppard award for niceness etc. Popularity contests are won by making large numbers of people happy, and large numbers of those large numbers are happy when they're deluded into thinking their job is worthwhile, so finding ways to actually sack them is the quickest way of getting unelected. The Cabinet Office spends way, way, way more time thinking about what people will think of what they're doing, than whether what they're doing will work.
