An example of something created to keep the Pentagon from wasting money is DAWIA, sounds great to train people in how to get better contracts and to track the performance of acquisitions, but it turned into an empire that has to cost a ton of money. Also the people, those high up with experience that actually make decisions, were exempted from taking all the classes. It takes many classes to become DAWIA certified now, the DAU (defense acquisition university) has a fancy building in Wildwood and many employees itself.
The idea is that this will be different. Not the bullshit money grab it's been in the past where they contract a group to study something that they already know is a problem and have people who are supposed to be taking care of it. "Oh no, this is a group to oversee the group that's there....."
Bureaucrats don't want to solve a problem, they just want to make it look like they're solving a problem while they piss around and surf for internet porn. Instead of doing their job, they hire a bunch of someones to do their job, which never gets done and the someones keep coming back for more money because "the job is bigger than we thought it was..."
Then they have to train everyone to be able to do their job, that they're supposed to already know how to do, which involves as you said more money for buildings and materials and staff.
The most recent personal example of this on a smaller scale was with Soulless Inc where they brought on a contract team to teach a member of each location to do basically desktop publishing. I explained to my 2-steps up boss that I was already proficient in this, was extensively familiar with the software, and would be happy to skip the training and teach my team, or give up my space to one of my co-workers. He appreciated my gesture but no, everyone tapped must attend.
So I attended - it was a Zoom series - and found that pretty much everyone in the class already knew this stuff, in fact we were more familiar with it than the instructor. So it cost them a piss ton of money to teach people things they already knew how to do.
Large entities don't like to use what they have, they want to buy more. That's some of what DOGE is targeting.
