Pardon my cynicism, but this doesn't really change anything. These companies are still evaluating their employees, just informally. They are still promoting and firing people. There are still teams who are doing well and teams that are not. There are teams that picked the right goals and met them, and teams that failed to deliver on their promises for yet another quarter. There are still teams with happy stakeholders and teams that infuriate everyone whom they interact with. It doesn't matter how you measure it or try to ignore it, the buck still stops with the manager of each team.
