I'm thinking about only surfacing data when there is a huge gap between someone's performance and the average/median in a team.

I'd like to have metrics that would keep managers in check. I was thinking about adding team metrics, and attributing drops to the managers. Espetially now that I have data coming several teams from different companies, I can safely attribute that to managers when it deviates too much from the "global average".

Let me know if that makes sense.
