Earlier quoted context omitted.
"output" only matters if your company is paid by "results" and isn't based on billable hours, otherwise ... "output" doesn't matter. Law firms would love every case to be solved in 2 hours if they still got the same $ value from a case that dragged on for 6 months.
Keep moving those goalposts.
You literally said "output" the most speculative / vague definition of "work" available.
I appreciate programmers / "creatives" "output" is much harder to measure, but there are alot of jobs where "mouse moving", "words per second" is a very reliable indicator of "output".
