It depends on the situation:

What you inherited was a mess, and if you want to be a hardliner and change the current situation, just talk about the poor performance, possible reasons, and previous Don't carry your bad performance into future jobs or anything like that. Let’s work together to change the status quo in the future.

What I took over was a good situation: thank you for your previous efforts, but there is still room for improvement. Let’s work together to do better, and everyone will get lots of bonuses and so on.

Haha, my personal opinion is that now that you are a supervisor, you will have some ideas.
