The "assemble the right team" part is pretty crucial here I´d say. Without a well fitting team there´s not much to manage. I´ve had some bad experiences with that in the past. If the team members have problems amongst themselves, it is very hard to get stuff done in the first place.
Assembling the right team is important, but sharing the load is way more important, imho. I've been on teams where one person does the bulk of the work and the others take credit. If you can track what is being done and by whom, you'll be more successful.
