Is bigger really better?

Conventional wisdom tells us that when facing a really big task or project we need to recruit a big team in order to tackle it effectively. However, I have read two different things over the past two days (Deuteronomy Chapter 20 and Seth Godin’s book Tribes) that suggest that what is more important than the size of your team is the commitment and focus of your team. A small group of committed and focused people is going to accomplish far more than a large group who are just showing up for a pay check, out of obligation, or for any other reason other than because they are committed to your purpose.
