Robert Katz identified three leadership skills called - technical skills, human skills, and conceptual skills as the basic personal skills essential for leadership. Leaders must possess these three skills that assist them in optimizing a leader's performance. Technical skills are related to the field, human skills are related to communicating with people and conceptual skills related to setting the vision.
According to the three-skill approach of Katz, the individual's leadership abilities vary depending on where leaders are in a management hierarchy. The practical implication of skills approach to leadership is that leaders can improve their capabilities in leadership skills through training and experience.
