In short
On December 1, 1913, Henry Ford's Highland Park plant in Michigan introduced the first moving assembly line for the Model T—a conveyor system that brought the work to workers instead of the other way around. The innovation cut assembly time from 12 hours to 93 minutes per vehicle, making cars affordable for ordinary Americans and establishing a manufacturing template that would dominate industrial production for a century.
How it unfolded.
The five-minute version
What actually happened.
An assembly line, often called progressive assembly, is a manufacturing process where the unfinished product moves in a direct line from workstation to workstation, with parts added in sequence until the final product is completed. By mechanically moving parts to workstations and transferring the unfinished product from one workstation to another, a finished product can be assembled faster and with less labor than having workers carry parts to a stationary product.
