I’m arguing that it’s unwise to trust someone to do an evaluation who has a personal stake in the result of that evaluation. Looking at how well a team works together to advance company goals is an important factor in any evaluation system, but using that as the only factor in a manager’s evaluation is as shortsighted as evaluating a software engineer solely on how many LOC they produced. In practice, overall team performance should be a factor in IC evaluations as it’s reflective of various hard-to-quantify contributions of the team members. It should also be a somewhat larger factor in a manager’s evaluation, with the weight between IC and team performance shifting from mostly-IC at the bottom of the hierarchy to mostly-team at the C-suite level.
