In 1798, Eli Whitney began using the process of interchangeable parts. This process involves large quantities of uniform pieces. Interchangeable parts opened the way for producing many different goods through mass production. These advances helped promote the assembly line production. In an assembly line, workers construct products more efficiently by dividing labor into specialized tasks. Each worker produces one part of the product. These innovations in manufacturing spilled over into the development of other industries, including banking, transportation, and communication.
