What development helped speed up manufacturing of products such as automobiles?

Answer 1

The development of the assembly line by Henry Ford in the early 20th century revolutionized manufacturing and significantly sped up the production of automobiles. The assembly line allowed for the standardized and efficient production of cars, as workers were able to focus on a specific task rather than building an entire car from start to finish. This led to increased productivity, reduced costs, and allowed for mass production of automobiles.
