Not a great fan of IDS or the administrations he was part of or the Universal Credit system as it exists, but I don't think he's wrong about the project - finding experts and paying them what they are worth, fostering collaboration, and using phased releases to evaluate how the tools work in practice is the best way to go about work at this scale.
Is it obvious? Absolutely. It should be the least anyone does, but it seems like they've come out ahead of many large scale projects by doing the basics. I hope other departments do learn from it.
