Is the original ideas about organizational design formulated by Fayol and Weber are now largely obsolete?

While Henri Fayol and Max Weber laid foundational concepts for organizational design, their ideas are not entirely obsolete but rather evolved. Contemporary organizations often blend traditional principles with modern approaches like agility, technology integration, and employee empowerment. However, fundamental concepts such as hierarchy, division of labor, and management functions still inform current practices, although they may be adapted to fit today's dynamic environments. Thus, while the original ideas have transformed, their core principles continue to influence organizational design.
