you are lucky. I enjoyed my XO time.

Have a good tracker/board or spreadsheet w/ 5Ws, most importantly when something is due, and where you check progress (IPRs). Importantly, who does what, and ensuring they understand up-front and will cash that check.

Do not let people not meet their obligations. Do not micromanage as in, if it takes them longer to complete, its their time, not yours, as long as they meet every gate/every IPR or progress-review. Some work faster than others.

List out on your board ALL the things you must do. Determine what others can do vs. what demands your personal attention. You should execute few things yourself, but manage many.
