> So how do you deal with bad developers?

The same way we deal with good developers? With managers, of course. That's the whole point of their role. Every developer productivity metric I've seen speaks to some disparity between engineering and the C-suite. I don't understand where these products originate that seek to do the manager's job for them but worse. I've been in management roles before, the numbers don't and can't always tell you the full story, no matter the size of the team or the quality of the data.

As always, good people are hard to find.
