The factory system is a method of manufacturing using machinery and division of labour. Because of the high capital cost of machinery and factory buildings, factories were typically privatized and owned by wealthy individuals who employed the operative labour. Use of machinery with the division of labour reduced the required skill level of workers and also increased the output per worker.
The factory system was first adopted in Britain at the beginning of the Industrial Revolution in the late 18th century and later spread around the world.[1] It replaced the putting-out system. The main characteristic of the factory system is the use of machinery, originally powered by water or steam and later by electricity. Other characteristics of the system mostly derive from the use of machinery or economies of scale, the centralization of factories, and standardization of interchangeable parts.
Although opportunity cost is definitely important, it is hard to put a "price" on the opportunity in many cases, which makes it unmeasurable. This is why economists focus almost exclusively on price.

The major impact of technology on World War I (WWI) was that it made the war much more difficult for the infantry soldiers who did most of the fighting. The new technologies led to trench warfare and the lack of new tactics led to massive slaughter at the hands of the new technology.
New technology in the form of machine guns and rapid-fire artillery gave a huge advantage to any army fighting on the defensive in this war. When the war settled down into stalemate on the Western Front, each side had really good defensive positions with their machine guns and their artillery.
Technology also had other impacts. Technology in the form of tanks and airplanes helped to eventually end the conflict. However, the main impact of new technology was to make this a war that resulted in huge numbers of casualties due to the advantages enjoyed by defenders.
