An authoritative leadership style, also known as autocratic or commanding, refers to a central decision maker who has authority and demands accomplishment without input from followers. A famous theorist, Milgram, proved how authority impacts normal human behavior. For psychological needs like being right or liked, humans will blindly obey leaders they trust, regardless of cultural values. Coaching is defined as equipping individuals through experience to develop careers. Challenges include time and openness, but benefits are increased knowledge, confidence, competence, excellence and commitment.
