Henry system for making cars increased efficiency by?
The Henry Ford system, specifically the moving assembly line, increased efficiency by dramatically reducing the time it took to manufacture a car. While there's no single percentage figure universally agreed upon, the impact was massive. It shifted car production from a painstaking, handcrafted process to a highly efficient, standardized one, slashing production time from approximately 12 hours per car to about 93 minutes by 1914. This represented a many-fold increase in efficiency.
