In keeping with the parable style, Lencioni (The Five Temptations of a CEO) begins by telling the fable of a woman who, as CEO of a struggling Silicon Valley firm, took control of a dysfunctional executive committee and helped its members succeed as a team. Story time over, Lencioni offers explicit instructions for overcoming the human behavioral tendencies that he says corrupt teams (absence of trust, fear of conflict, lack of commitment, avoidance of accountability and inattention to results). Succinct yet sympathetic, this guide will be a boon for those struggling with the inherent difficulties of leading a group. 100,000 first printing. (Apr.)
