I can't remember the GAO ever doing investigations on government inefficiency. Mostly I see reports from them on where projects are blowing out budgets or instances where the government isn't properly reporting to the public. They don't identify solutions to problems usually, just point out the problems.

The same as the difference between the Department of Redundancy Department and the Bureau of Standard Acronyms
