Project management has existed in some form for thousands of years. After all anything that requires an approach where humans organize effectively to a plan and achieve specific objectives can be loosely defined as a project (see Great Projects from the Past). How else would have humans achieved some of stunning wonders and achievements.

For example, the Great Pyramid of Giza (2,550 B.C.) or the Great Wall of China (221 B.C. – 206 B.C.).

The pace of development continued in and around the Mediterranean, the Middle East and Asia Minor, and the harnessing of animal labor in carrying materials. This led to projects like those that created the Roman Coliseum, 80 A.D.
