Project management has existed since ancient times, historically related to civil works construction engineering projects (such as hydraulic engineering projects in Mesopotamia, where logistics or the creation of work teams came into play, with their professional categories defined, or the engineering culture developed by the Roman Empire, where the control of costs and times appears and the application of standardized solutions, such as in the construction of a road), and in "military campaigns", where they also come into play many management elements (identification of objectives, human resource management, logistics, risk identification, financing, etc.). But it is from the Second World War onwards that the advancement of these techniques from a professional point of view has transformed Project Management into a research discipline.
