in the latter half of the 18th century, the production elements became less reliant on the location of the power source, and so the processing of goods moved to either the source of the materials or the location of people to perform the tasks. Separate processes for different treatment stages were brought into the same building, and the various stages of refining or manufacture were combined.

introduced the innovation of continuously moving the cars being assembled past individual workstations. This introduced the idea of standardization. The assembly line was a contraption of many chains and links that moved to place different parts into various places throughout the car. The chassis of the car was moved along the 45-metre line by a chain conveyor and then 140 workers applied their assigned parts to the chassis. Other workers brought additional parts to the car builders to keep them stocked. The assembly line decreased the assembly time per vehicle. The production time for a single car dropped from over twelve hours to just 93 minutes.
