Patrick Lencioni’s The Five Dysfunctions of a Team came out in 2002. It is a business fable. The book reached the best-seller lists of The New York Times, BusinessWeek, The Wall Street Journal and USA Today.
Lencioni names five problems: absence of trust, fear of conflict, lack of commitment, avoidance of accountability, and inattention to team results. In the last one, members focus on “personal success, status and ego before team success.”
