Rating system needed
Since the government is very fond of rating systems, such as those used to rate schools. How about if they implemented the same thing for the outsourcing companies that they use across all government programmes. Then they could try and work out which ones are no good, so that they don't keep making the same mistake.
The trick is that they need to consider cost, risk and time. Just because it was cheapest, doesn't mean that they will get it right.
You would also assume that with a win on a £239M cointract, they could afford at least a handful of competent people to drive it forwards properly
Given the number of things that have been reported to be visible and wrong, you can be fairly confident that the same sort of level of quality will exist all through the platform.
