Assembly line

A system created by Henry Ford to cut manufacturing costs and deliver a cheaper product.

Yes, but what is an assembly line?

An assembly line is a process as much as a thing. The idea was that rather than have workers construct a car wholesale, many more workers would be used, each of who constructed a component of the car. This allowed the individual workers to specialise and become very fast at what they did. The car bodies themselves moved along a moving line which is where the term assembly line comes from, as all the parts were already made, they just had to be stuck in place.
