Using division of labor, relentless cost-cutting and process optimization, the factory went through an experience curve to reduce price and increase volume. On October 7, 1913, the Highland Park Ford Plant became the first automobile production facility in the world to implement the moving assembly line. The new assembly line improved production time of the Model T from 728 to 93 minutes. The Highland Park assembly line lowered the price of the Model T from $700 in 1910 to $350 in 1917, making it an affordable automobile for most Americans. On January 5, 1914, Ford announced that factory wages would be raised from a daily rate of $2.34 () to $5.00 (), and that daily shifts would be reduced from nine hours to eight. After the increase in pay, Ford claimed that the turnover rate of 31.9 percent in 1913 decreased to 1.4 percent in 1915. Ford offered nearly three times the wages paid at other unskilled manufacturing plants.
