Open, frank communication is the lynchpin to teamwork. A fractured team is like a fractured bone; fixing it is always painful and sometimes you have to re-break it to heal it fully - and the re-break always hurts more because it is intentional.

If the CEO's behavior is 95 per cent healthy while the rest of the organization is only 50 per cent sound, it is more effective to focus on that crucial and leveraged 5 per cent that makes up the reminder of the CEO's behavior.

A core value is something you're willing to get punished for.

Remember teamwork begins by building trust. And the only way to do that is to overcome our need for invulnerability.

It's as simple as this. When people don't unload their opinions and feel like they've been listened to, they won't really get on board.

Teamwork remains a sustainable competitive advantage that has been largely untapped because it is hard to measure (teamwork impacts the outcome of an organization in such comprehensive and invasive ways that it's virtually impossible to isolate it as a single variable) and because it is extremely hard to achieve (it requires levels of courage and discipline that few executives possess) - ironically, building a strong team is very simple (it doesn't require masterful insights or tactics).

Really great people rarely leave a healthy organization.
