He sets the vision and drives the team.

Reminds me of a recent story about the most recent rocket engines from SpaceX. Elon pushed his team for scaling up an efficient design of rockets, which till then was only done with lower powered engines. Elon took a look at the tech, came to a decision that scaling up is a reasonable risk/reward trade-off and demanded his team go ahead with it. His team balked, but made it happen.

I remember the leader of the team specifically thanking Elon, saying that without his push, they would not have done it.

It takes a lot of guts, knowledge and confidence in yourself and your team to make such decisions. edit : https://news.ycombinator.com/item?id=19153953
