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).

If you could get all the people in an organization rowing in the same direction, you could dominate any industry, in any market, against any competition, at any time.

. . . his biggest problem was his need for a problem.

Great teams do not hold back with one another. They are unafraid to air their dirty laundry. They admit their mistakes, their weaknesses, and their concerns without fear of reprisal.

Not finance. Not strategy. Not technology. It is teamwork that remains the ultimate competitive advantage, both because it is so powerful and so rare.

Choose your companions before you choose your road.

Really great people rarely leave a healthy organization.
