Division of Labour.

Division of labour (also spelled labor) is a system in which workers divide a manufacturing task into various steps, with each worker responsible for performing one step. This system replaced traditional manufacturing processes in which a single expert laborer would perform every step, start to finish, in the creation of a good. Division of labor was a critically important aspect of the Industrial Revolution and the rise of mass production in industrialized nations, and it contributed to an enormous increase in the output and efficiency of factories. Many sociologists and economists have praised the system for its efficiency and cooperative nature, while others have criticized the monotony and limitations it has created for modern workers.
