The fact is, employees cannot make breakthroughs if they can't openly and honestly disagree with their peers and their leader. Indeed, great leaders don't just permit conflict; they actively try to elicit it from reluctant employees as well.

I have yet to meet members of a leadership team who I thought lacked the intelligence or the domain expertise required to be successful. I've met many, however, who failed to foster organizational health. Their companies were riddled with politics, various forms of dysfunction, and general confusion about their direction and mission.

The truth is that intelligence, knowledge, and domain expertise are vastly overrated as the driving forces behind competitive advantage and sustainable success.
