The document discusses Patrick Lencioni's four disciplines model for building a cohesive leadership team. The four disciplines are: creating clarity by answering six questions; overcommunicating clarity; reinforcing clarity through recruiting, performance reviews, recognition, and firing; and building trust and commitment among team members by engaging in productive conflict. An effective leadership team is small, trusts one another, engages in unfiltered discussions, makes clear decisions, and holds each other accountable to commitments and behaviors.
