It is just and idea and we hit the issue in my team currently. We want to use the PHABRICATOR to manager our development in whole, then we also want to get some performance report for each developer. I think we have below aspects
1. Code lines (Changed or added)
2. Bugs (Resolved or Opened)
3. Tasks (Resolved)
4. Inline Comments (Raised and Be Raised)
5. Time Cost (Resolved)
We want to use such report to do evaluation. but it is not a mature idea currently. not sure if u guys has such plan, and idea.
