Building the Great Pyramid is what we today would call a large-scale project, and stands representative of numerous projects

from early recorded history that required massive human works and managerial competency.  

With later civilizations, we can cite the Great Wall China which is yet another wonder of the world 

that was built since the Qin Dynasty (221BC-206BC). Available historical data, shows or

indicate that the labor force was organized into three groups consisting of soldiers, the common people and criminals.

The overall command was Emperor Qin Shihuang who ordered millions of people 

to finish this project. This shows emergence of organization, and command structure in project execution (Figure 1.2).
