Can anyone here look at "
identify a change which improved employee efficiency by $125 annually" and think it isn't going to be complete bullshit? That's in the region of 50c/day. "I told employees to reuse paperclips which I predict will save the company $1M per year"[1] PR/marketing/self-promotion - surely nobody believes it?. And that saving 50 cents per day is supposed to come from a manager who can influence all 8000 employees, but who doesn't think to axe the useless reporting department to save $1M/year in one go? And then the company which keeps a $1M department just to sound good is going to identify $1M in piecemeal efficiency improvements year on year, every year?
Who believes this?
Although I don't completely disagree, see[2][3] "Another reason to have in-house expertise in various areas is that they easily pay for themselves, which is a special case of the generic argument that large companies should be larger than most people expect because tiny percentage gains are worth a large amount in absolute dollars. If, in the lifetime of the specialist team like the kernel team, a single person found something that persistently reduced TCO by 0.5%, that would pay for the team in perpetuity, and Twitter’s kernel team has found many such changes."
But then again, at the bottom of [4] "At multiple companies that I've worked for, if you tally up the claimed revenue or user growth wins [of people claiming they improved things X amount per year] and compare them to actual revenue or user growth, you can see that there's some funny business going on since the total claimed wins are much larger than the observed total." which is pretty much my criticism of your comment; people will embellish their claims, especially when nobody can easily prove or disprove a claimed 50cent/day efficiency improvement over 8000 employees.
> "usually a hyperfocus on really insignificant numbers as evidence of their point."
$1M is roughly an average UK household income, after tax, for a lifetime. This just reads like dismissive boasting rather than a useful part of your comment. If it's "really insignificant" why do you then argue that the company will be motivated to save it in a more difficult piecemeal fashion, year after year five times over, if they aren't motivated to save it once in a big lump?
