I wholeheartedly endorse the RawSignal team’s take on performance reviews:

A great performance review is not an evaluation conversation, it’s an alignment conversation. It shouldn’t be a conversation about which things happened, it should be a conversation about which things matter. It’s an opportunity for you and your person to get onto the same page about where you’re seeing the work differently, because that is informative in terms of how the next year is going to feel.
