Research has been done on the theory and correlation of emotional intelligence (EI) related to organizational success and long-term sustainability of a manager/leader in his or her career. Many leadership/management experts argue that successful manager/leaders demonstrate a sophistication of EI that differs vastly from those managers/leaders who eventually fall and fail their organizations. Some of the key factors of EI include self-awareness, impulse control, persistence, confidence, self-motivation, empathy, social deftness, trustworthiness, adaptability, and a talent for collaboration. Effective managers/leaders are very successful at articulating their missions and visions for their organizations and know how to bring everyone on board to accomplish them. Compare and contrast the "transformational" manager/leader with the "transactional" manager/leader. Who do you think can better take the pulse of a group, understand its unspoken currents of thought and concerns, and communicate with people in terms they can understand and embrace?
