What are the benefits of division of labour?

Context: The division of labour is the separation of the tasks in any economic system or organization so that participants may specialize. Individuals, organizations, and nations are endowed with or acquire specialized capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialized capabilities may include equipment or natural resources as well as skills. Training and combinations of equipment and other assets acting together are often important. For example, an individual may specialize by acquiring tools and the skills to use them effectively just as an organization may specialize by acquiring specialized equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence.

Historically, an increasing division of labour is associated with the growth of total output and trade, the rise of capitalism, and the increasing complexity of industrialized processes. The concept and implementation of division of labour has been observed in ancient Sumerian culture, where assignment of jobs in some cities coincided with an increase in trade and economic interdependence. Division of labour generally also increases both producer and individual worker productivity.

After the Neolithic Revolution, pastoralism and agriculture led to more reliable and abundant food supplies, which increased the population and led to specialization of labour, including new classes of artisans, warriors, and the development of elites. This specialization was furthered by the process of industrialization, and Industrial Revolution-era factories. Accordingly, many classical economists as well as some mechanical engineers, such as Charles Babbage, were proponents of division of labour. Also, having workers perform single or limited tasks eliminated the long training period required to train craftsmen, who were replaced with less-paid but more productive unskilled workers.

Answer: In general the following benefits are associated with increasing division of labour:
- increase in total trade 
- increase in total output
- an increase in market activity
- increased specialization
- increasing complexity of industrialized processes
