Jim Keller did a talk somewhere on YouTube about his experience at AMD on the zen project, and one of the things he highlighted in that process was figuring out what was going on with people that was preventing them from working well on the project. Getting at the deeper causes made it easier to try to find mutually beneficial solutions even if those were the employee moving on from the team. People problems are messy though, and you will definitely feel like the bad guy in some cases, even if you are trying to do what is best for everyone.
