3. Henry Ford
Henry Ford realized that he would a more efficient way to mass produce cars in order to lower the price. He looked at other industries and found four principles that would further their goal: interchangeable parts, continuous flow, division of labor, and reducing wasted effort. Ford put these principles into play gradually over five years, fine-tuning and testing as he went along. In 1913, they came together in the first moving assembly line ever used for large-scale manufacturing. Ford produced cars at a record-breaking rate forever changing the automobile industry.
