1914 – Henry Ford announced the new continuous motion method to assemble cars.

The moving assembly line appeared to the onlooker to be an endless contraption of chains and links that allowed Model T parts to swim through the sea of the assembly process. In total, the manufacturing of the car could be broken down into 84 steps. The key to the process, however, was having interchangeable parts.

Unlike other cars of the time, the Model T featured interchangeable parts, which meant that every Model T produced on that line used the exact same valves, gas tanks, tires, etc. so that they could be assembled in a speedy and organized fashion. Parts were created in mass quantities and then brought directly to the workers who were trained to work at that specific assembly station.

The chassis of the car was pulled down the 150-foot line by a chain conveyor and then 140 workers applied their assigned parts to the chassis. Other workers brought additional parts to the assemblers to keep them stocked; this reduced the amount of time workers spent away from their stations to retrieve parts. The assembly line significantly decreased the assembly time per vehicle and increased the profit margin.

The immediate impact of the assembly line was revolutionary. The use of interchangeable parts allowed for continuous work flow and more time on task by laborers. Worker specialization resulted in less waste and a higher quality of the end product.

Sheer production of the Model T dramatically increased. The production time for a single car dropped from over twelve hours to just 93 minutes due to the introduction of the assembly line. Ford’s 1914 production rate of 308,162 eclipsed the number of cars produced by all other automobile manufacturers combined.
