Achieving vulnerability-based trust (where team members have overcome their need for invulnerability) is difficult because in the course of career advancement and education, most successful people learn to be competitive with their peers, and protective of their reputations. It is a challenge for them to turn those instincts off for the good of the team, but that is exactly what is required.

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.

The impact of organizational health goes far beyond the walls of a company, extending to customers and vendors, even to spouses and children. It sends people to work in the morning with clarity, hope, and anticipation and brings them home at night with a greater sense of accomplishment, contribution, and self-esteem. The impact of this is as important as it is impossible to measure.

There is just no escaping the fact that the single biggest factor determining whether an organization is going to get healthier - or not - is the genuine commitment and active involvement of the person in charge.

Building a strong team is both possible and remarkably simple. But is painfully difficult.

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).

Success is not a matter of mastering subtle, sophisticated theory but rather of embracing common sense with uncommon levels of discipline and persistence.
