New job: From CS to Growth and Scaling

Hello!

Looking for some helo from anyone with some experience in growth and scaling.

I built a CS department which is now pretty self-running and I'm being tapped for a position where I can help grow and scale the entire company. I believe this will include Marketing, Sales and Customer Success. I have a few questions for anybody who might have some experience in this:

• What would be your first order of business?
• Has anyone worked with a structure with departments where you have leaders instead of traditional manager positions (in order to keep a flatter structure?
• What learnings can you bring from CS to implement in other departments?
• If I get a formal offer, what kind of initial plans would you recommend I present to the board (initial review of all processes, request for full control of everything from marketing down to cs, budget, etc)?
• Do you know of any good resources related to growth and scaling?

Sorry of the questions are a little over the place
