Loved the new direct first day interview podcast.  My question is - does this discussion work on MY first day?

I have my first day in a new management position with a new team in a couple of days.  I've had some turnover time, so I've met all my directs already with my predecessor.

I'm already planning to have an initial staff meeting to give the "I'm not that smart and you're not that dumb" speech from the "fit in" podcast.  I'm considering including this new direct discussion about integrity, kindness, and results into that meeting.  Alternatively, I'm wondering if I should do it one on one with each direct instead as a way to kick-off O3's.
