Have stayed out of this thread so far and this post may be a mistake, but here goes ...
I have had anywhere from 25 - 200 people reporting to me on technical programs over the course of the last 10 years. I am directed/required by my management team to provide weekly activity reports on what my team is doing. This is three separate management chains, two are internal and one is a required input by my Government Customer. They all get the essentially the same report but it is formatted differently for each as they use different tools/practices to extract the items they want to pass on to their higher ups. I ask everyone of my team to provide me a bulleted list of what they did that week and what the upcoming major activities/events they are focusing on for the next week (if it applies). I can usually generate 60-70% of what my team provides me without their input but there is no way I can know everything they do on top of doing my own work. There are always items that they highlight that I am unaware or only vaguely aware of. Is it tedious at times? Yes. Is it efficient? Wrong question. The goal is not to confirm they are doing something useful or valuable, it is to track their status against their contributions to planned deliverables that I am responsible for and if they are falling behind, I can step in and help them directly or find resources for them to help themselves. And yes, it can identify where someone is not performing where I need them to be. The USG Customer wanted to track every dollar against each task/deliverable as well as using the info to actually understand the work being done. On top of the weeklies, I had to prepare monthly and quarterly reports to the same USG customer. Those are redundant and inefficient but were contractual deliverables. I won't speculate on the why relative to DOGE/Musk, but bitching about spending 5 - 10 minutes a week (0.2-0.4% of a normal work week) to highlight work completed is lame.
Just my experience in the private sector working with a USG customer. Value it as you will.
