I know that any group of people can become a team if they do the right things, but I came to realize over time that if you acquire or develop the right kind of people, that process of building a team is going to be much more effective and easier.

The kind of people that all teams need are people who are humble, hungry, and smart: humble being little ego, focusing more on their teammates than on themselves. Hungry, meaning they have a strong work ethic, are determined to get things done, and contribute any way they can. Smart, meaning not intellectually smart but inner personally smart.

Team members have to be focused on the collective good of the team. Too often, they focus their attention on their department, their budget, their career aspirations, their egos.

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).

Clients don't expect perfection from the service providers they hire, but they do expect honesty and transparency. There is no better way to demonstrate this than by acknowledging when a mistake has been made and humbly apologizing for it.

Your focus should be on creating an environment where growth can occur and then letting nature take its course.
