Abstract
Most Economy books define manufacturing as the past of Operations management. O.C Ferrell, Professor at the Colorado Sate University explains that this is due to the fact that operations management at first was only concerned with the production of physical goods. He also defines manufacturing as "the activities and processes used in making a tangible product, also called production." [1] with accordance to that definition, it is difficult to date the real origins of manufacturing. We could come back to the primary workshops that made items in a relatively significant number with the aim of exchanging or selling them. The role of the people in charge of the production has continuously improved with evolution. In the Roman, army for example, some people had to oversee the making of the weapons and certainly faced some problems with raw materials or with people employed for that task. But these roles in the production of goods took a greater sense with the Industrial Revolution.
