After 20 years of focus on teaming in industry, teamwork effectiveness in IT projects remains hit or miss. While some teams are highly effective and others highly ineffective, most are of middling effectiveness. Statistics on IT project success support this observation all too well.

Why does this condition persist? Is this the way it has to be? If not, what will increase team effectiveness across the board?
