In 1955 Prof. Robert Katz developed the three managerial skill model.
According to Katz, there are three managerial skills that every manager needs.
- Technical Skills - the ability to perform the given job. The lower-level managers require more technical skills.
- Human Relations (Interpersonal) Skills - the ability to understand, communicate and work with people. Human relations skills are required by all managers at all levels of management. The reason for that is all managers have to interact and work with people.
- Conceptual Skills - the ability to see the big picture, to visualise the organisation as a whole. It includes analytical, creative, problem-solving skills. The top-level managers require more conceptual skills and less technical skills.
Managers working at different levels of management require different levels of skills. The level of importance of each skill set is directly correlated with the management level that the person has in the organization. As managers moves up in the organization, they need more conceptual skills and less technical skills.
