What does the unit do well? Don’t take those things for granted and keep your focus on them.
Could they be better? As per JoT, just a small tweak could make a big difference.
What does the unit not do at all or is its greatest weakness? Pick one, plan with your staff how it could be fixed.
Have an open discussion with your staff, set expectations of each other, find out what responsibilities they have and are happy with, is there anything that could be shuffled with agreement, how can you best facilitate their success, is there anything they want to or could develop personally…?
Don’t forget that your fellow CFAV need attention too.
Give them the bones of your vision (doesn’t have to be grand - my eg above would be “maintain performance in x, build on the success of y, introduce/improve z”) and plan with them how to achieve it, or even if they think it’s possible.
Delegate! You don’t have to keep all of your old jobs, especially if they will take time away from doing your new ones.
There’s no need to rush - if one project takes off or takes longer, don’t start another. Don’t do it day one (we’ve got enough new to handle atm anyway).
Get to know your committee and their plans/ideas, they need to know yours too. Do any want to do more? They’re invaluable when alongside you, but can derail more than you might think.
Be honest, open minded, and collaborative at all stages.
That’s my short, vague response, having been through similar in recent history myself.
