The best way to be in charge of something is to embrace the mess.
Of course, you should be committed and you should deeply care. You should bring your A-game and make sure that everybody involved can bring their own too. You should plan and execute and iterate and educate and plan some more.
And then, when chaos strikes, as it certainly will, you should be ready to throw everything in the air and play with the mess of the new setting.
It might not only be the best way, but also the only one.
