Management theories and practices have evolved over thousands of years through different eras:
- During the pre-historic era from 10,000-9000 BC, the earliest forms of management could be seen in how hunter-gatherer tribes organized to hunt animals and gather food.
- Ancient civilizations from 10,000 BC to 475 AD displayed more advanced management with structures like the Egyptian pyramids and Chinese Great Wall, as well as early concepts of job specialization.
- The medieval period from 476 to 1500 AD saw further developments like the establishment of job descriptions and use of delegated authority.
