Managerial skills refer to the abilities needed by managers to be effective. According to Professor Robert Katz, there are three core managerial skills: conceptual skills, human relations skills, and technical skills. Conceptual skills involve seeing the big picture and creative problem solving. Human relations skills center around interacting with and motivating people. Technical skills pertain to specialized knowledge and operations. While all managers need these skills, the balance required varies by management level, with top managers needing more conceptual skills and lower managers requiring greater technical expertise. Communication, leadership, problem solving, administrative, and decision making abilities are also important managerial competencies.
