Cool facts
Moving, not stationary. Instead of workers walking around carrying parts, the product moves along a line from workstation to workstation. This saves time and energy because everything comes to the workers instead of the other way around.
One job per person. Each worker at a station adds just one or two parts to the product, then it moves to the next station for the next step. Doing one thing really well and repeatedly makes workers super fast.
Speed and less work. Assembly lines let factories make finished products way faster than the old way, and they need fewer workers to do it. This is why so many things we use today are made this way.
Changing how we make stuff. Assembly lines revolutionized factories and made products cheaper for regular people to buy. It's one of the most important inventions in how we manufacture things.
