In any large enterprise there will be WF&A. I saw it where I worked, tons of it, and much smaller operation. I don't think it practicably can be reduced much. I mentioned before this DOGE effort, to me, looks like a scam. Maybe they identify some wasteful spending here and there, that wouldn't be hard, but then you really need Congress to go along with cutting it, as they did recently to the tune of ... $9 billion (maybe). Great, but rounding error.
Real cuts would have to be where the major spending happens, which includes the defefense budget, and if you don't think it's replete with WF&A I can't help. We at least see consistent major cost overruns in weapons programs. Why? They basically present a best case scenario to win the contract and then run into predictable problems with delivery (F35). The Army has been trying to replace the M16 with a new weapon for years now and the proposed model is apparently failing in field testing.
The Ford class aircraft carriers are all running well over budget with delivery delays, same for every other major weapons program. Would we tactically be better off with more smaller carriers using the F-35B? Maybe.
