After the Vietnam war, in the 1970s, there was a big RIF (reduction in force) at places like the NSA.
These agencies have not had a reduction since then and are oversized and wrongly sized.
The same issue faced the US Army prior to WWII. Roosevelt's solution was to find a young general (he found Marshal) and have him get rid of the dead wood because it was expected we'd be in a war in a couple of years.
Marshal created the "plucking commission" and got rid of a lot of dead wood. This put the US in a much better position to fight a war.
