The Ford Motor Company installed the continuous moving assembly line for the mass production of an entire car, reducing the time it took to build a car from more than 12 hours to 2 hours 30 minutes. Ford broke the Model T’s assembly into 84 discrete steps, for example, and trained each of his workers to do just one. He also hired motion-study expert Frederick Taylor to make those jobs even more efficient. Meanwhile, he built machines that could stamp out parts automatically (and much more quickly than even the fastest human worker could).The most significant piece of Ford’s efficiency crusade was the assembly line. Inspired by the continuous-flow production methods used by flour mills, breweries, canneries and industrial bakeries, along with the disassembly of animal carcasses in Chicago’s meat-packing plants, Ford installed moving lines for bits and pieces of the manufacturing process: For instance, workers built motors and transmissions on rope-and-pulley–powered conveyor belts. In February 1914, he added a mechanised belt that chugged along at a speed of six feet per minute. As the pace accelerated, Ford produced more and more cars, and on June 4, 1924, the 10-millionth Model T rolled off the Highland Park assembly line.
