The division of labor is the process of separating the main task into sub-task so that each worker who is a specialist in that task can complete that task separately.
Different workers having different specializations perform different parts of production. The outcome is that goods come to the final shape with the cooperation of many workers.
For example Consider a large-scale ready-made garment factory, where a man does the cutting of cloth, the second man stitches clothes with machines, the third sticks buttons, and the fourth makes folding and packing, etc.
This way of doing cooperative work is called the division of Labour.
Final Answer:
When different workers perform different parts of production with cooperation and reach the final product is called division of power.
