All they did was to add another layer of bureaucracy over the top of existing departments, as I understand it. Ideally, they would eliminate redundancies post-merger, but this is government we're talking about.

If we coded the way the government governs, we'd never be able to remove bad code, we'd have to continually add more and more complicated code to fix the existing bugs and source control would also be an anathema, in particular because of the 'blame' command.
