When he first observed the factory,he noticed that each worker wasproducing his or her own pins. By the end of the day, the total production by each worker was 20 pins. He stated that each worker should specialize in the production stage rather than produce his or her own pins. Through specialization, the total output by the factory increased to 48,000 pins per day.(Page 11, Wealth of Nations)

One person draws the wire.One person straightens the wire.One person cuts the wire.One person points the wire.One person grinds the wire at the top to receive the head of the pin.One person makes the head of the pin.One person attaches the head to the pin.
