Too right! Having a good XO (2i/c) can make a huge difference, whether it's a PM or an executive assistant. My old boss was able to hand off a lot of the "figure out the budget and manage our spend" tasks to his right-hand PM and it made a HUGE difference. Not only was he a lot more relaxed knowing that was in good hands, we were all suddenly a lot happier knowing the budget was getting someone's regular, undivided attention!
