If you are factory line worker, yes.
If you are a developer or a manager (a "knowledge worker") -- what you could be observed to be doing has usually little correlation with result for the company.
I know people who are busy producing total crap, managers completing tons of projects achieving bad results, very energetically with huge fanfare. And I know admins that have everything so well automated and working reliably that they are watching youtube whole day, their managers none the wiser about what could have been. Or people who do nothing and have one brilliant idea a year that saves the company tons of expenses. And every other type inbetween.
In a lot of teams it is usual for senior developers to produce relatively little code compared to juniors, when looking at the value they are creating. Maybe because they spent most of their time doing other things like helping juniors, doing code reviews, designing new solutions, talking to clients. Or maybe because they are getting the most complex problems.
If you can measure this you would deserve Nobel Prize. A more likely explanation, though, is that you have no idea how complex the problem is.
In those cases I like to remind people of this famous little story: https://www.folklore.org/StoryView.py?story=Negative_2000_Li...
In my experience working many decades, in most teams there are few individuals who are making things go and frequently not even their direct managers understand how people are exactly contributing to productivity.
