My alternative suggestion would be to worry less about individuals and more worry about if the organization is producing something of value. After that, you can start to pick and prod at the individual contributions if you want, but expect that any team will likely have a step function that is their effectiveness. As such, you may remove the least functioning member of a team, and then find that you dropped the entire team to nothing. It is almost certainly true that there can be drags on the morale of a team. People that are causing things to go slower in detrimental ways. It is also almost certainly true that sometimes having someone around that is just fun to talk to for the rest of the team is enough to keep the entire team functioning.
