Other types of projects flourished with the development of new technologies. The European Renaissance led to the great European Voyages of Exploration of the 15th century with advances brought about by grids/maps, astrolabe, compass, lateen sail, and improvements in ship building (Caravel).
In the last 400 years there was a further evolution in project types. This was first influenced by the First Scientific Revolution that provided important discoveries and inventions, and impacts on Western society. This spawned the first phase of Modern Engineering and its influence on Project Management, and led to the First Industrial Revolution and the monumentous changes brought about it.
By the end of the 19th century the newly industrialized world with mass production required a system to supply large quantities of raw materials, resources, man power, equipment and organization. It needed more sophisticated systems of transportation, storage, manufacturing, assembly, and distribution. Further a rapidly expanding workforce of thousands needed to be taken care of in terms of housing, health, welfare, and education. All this brought in new institutions, establishments, and organizations.
These colossal changes in the Western World along with the Second Industrial Revolution required a far more structured and disciplined approach to business and management, based on scientific research and principles, as the scale of objectives changed. With this came the birth of management principles in the business world, to become the backbone of project management, driven by a few key individual contributors in the field.

The First World War mobilized continents with huge armies and resources into a global conflict which proved to be a prolonged war of stalemate. It manifested the industrialization of war and leveraged mass production, mass transportation, and mass mobilization. By 1918 the logistical operation supplying the British Expeditionary Force was the largest the world had ever seen. This further accelerated work in planning and supplying.
Between the two world wars new disciplines were added to the study of business management notably, human relationships (between employer and employee), an evolution in marketing (and its importance) and industrial human relations school of management arose to deal with the practical problems caused by Taylorism and the grindless repetition of tasks.
Project engineers developed or adapted coordination techniques that gave the managers control over the progress of the project but did not attempt to dictate to specialized experts how to do their work. MIT professor Erwin Schell articulated this philosophy, telling students in the 1930's:
"The work of the engineers in most departments is not sufficiently routinized to allow process control. The most satisfactory policy appears to be that of employing competent men and then holding them [responsible] for results in terms of the erection schedule, leaving ways and means largely to their individual discretion."
The Third Industrial Revolution, from 1940 to today, has been dominated by computers both electro-mechanical and electronic, information, and the Internet. It also saw the institutionalization of management practices into business. This was accelerated by the second world war which brought mega projects to the fore front. For example, the adaptive system created for the Battle of Britain (1940), the Collossus computers at Bletchley Park (1943), the Normandy Invasion (1944), and the Manhatten project (1945).
The Cold War reflected the manifestation of the third industrial revolution and the advances made in the use of information/intelligence in the second world war . It also saw the development of a large number of planes and rockets projects by the US Air Force and Navy based on experiments and prototypes in the Second World War.
