However, while the functions that Fayol considered the most important elements of managerial work are not what can be observed in the daily activities of managers, Mintzberg created some problems in his method of study to discover the nature of management. Furthermore, while Fayol failed to paint a picture of managerial work in reality, Mintzberg failed to give an idea of ​​what managers should do to be successful and effective. To some extent, Fayol and Mintzberd did not develop competing theories, but theories about different dimensions of managerial work. In terms of gaining effectiveness in management, Fayol achieved better results by indicating what managers should do rather than simply responding to the pressure of their work as described by Mintzberg. It can therefore be concluded that Fayol's work is superior to that of Mintzberg and that the latter is rather ineffective.
