A team is a group committed to a common purpose and goals, where members are mutually accountable. A team leader is the point of communication between the team and management and assists the team in implementing approved changes. Effective team leadership requires building trust, acting with coherence between words and deeds, having competence and surrounding oneself with competent others, fostering collaboration, driving the team towards excellence through competition, and ensuring all members contribute. Leaders must focus on the mission and inspire others, be authentic, courageous when challenged, and empathetic through open dialogue.
