My company doesn't officially measure metrics for developers. One thing my boss keeps track of is how many tickets get moved from one sprint to another, but not per-person, just as a team.<p>Quantifying human labor (especially knowledge work) is extremely difficult, and I think you need to just have an organic, on-the-ground view of it. Project managers that know how to code and what kind of work goes into a problem can better understand the level of effort for a particular problem, then you can see who is pulling their weight and who isn't.
