Where did Henry Ford get the idea for the assembly line?

Henry Ford drew inspiration for the assembly line from several sources, including the manufacturing processes of meatpacking plants and the flow production methods used in the production of shipbuilding. He also observed the efficiency of moving assembly lines in various industries and adapted these concepts to automobile manufacturing. By implementing a continuous flow system, Ford significantly reduced production time and costs, revolutionizing the auto industry and making cars more affordable for the average consumer.
