Well I pretty much see which team members are slacking and which are working hard.

But I do code myself, I write requirements so I do know which ones are trivial and which ones are not. I also see when there are complex migrations.

If you work in a group of people you will also get feedback - doesn't have to be snitching but still you get the feel who is a slacker in the group.

It is hard to quantify the output if you want to be removed from the group "give me a number" manager. If you actually do the work of a manager so you get the feel of the group like who is "Hermione Granger" nagging that others are slacking and disregard their opinion, you see who is the "silent doer" or you see who is "we should do it properly" bullshitter you can make a lot of meaningful adjustments.
