Assembly lines in factories (versus home manufacture), using interchangeable parts.
In the early 1900s, many African Americans migrated to northern cities to escape the oppressive conditions of the Jim Crow South and seek better economic opportunities. This movement, known as the Great Migration, saw individuals and families move to urban areas where they could find jobs in the assembly lines of new factories, particularly during World War I and the subsequent industrial boom. Additionally, European immigrants also contributed to the workforce in these cities, seeking jobs and a better life in America.
factories with production lines
Slaves organized into something that was similar to an assembly line. They did this long before the assembly lines were used to create vehicles.
Women had jobs of field nurses, jobs within the Salvation army, others had jobs at the war factories because most of the men had gone over seas to do the fighting.

Assembly line production made it faster to train workers and faster to make stuff. Boosted productivity and lowering the cost.
Assembly lines in factories (versus home manufacture), using interchangeable parts.
Factories during the Industrial Revolution from 1880-1920 were often too hot with slippery floors. Assembly lines moved at high rates of speed, resulting in worker fatigue and inattention to safety issues.
Henry Ford invented the assembly line to be a more effecient way to put things together. Assembly lines are now used in almost every kind of factory in the world.
After the development of mass production assembly lines, the next step is automated assembly lines. These lines use robotics instead of human workers to build items.
