A fascinating story of transforming a group of talented people into a winning team. A story told in the form of a business novel. A new leader comes to a technology company that is on the verge of decline and begins to establish the work of a management team, or rather, create a team anew. Patrick Lencioni describes five "vices" of any collective: mutual distrust, undemanding, irresponsibility, fear of conflict and indifference to results. Following the heroes, the reader finds out how to diagnose, eliminate and achieve the coordinated work of the team, taking into account the properties of human nature.
