An assembly line is a manufacturing process where a product is assembled in a sequential manner. Each worker or machine performs a specific task, allowing for efficient production. This method reduces the time it takes to create a product, as each component is added in a systematic way. Assembly lines are commonly used in industries such as automotive and electronics. The concept of the assembly line was popularized by Henry Ford in the early 20th century, particularly in the production of the Model T automobile. This innovation significantly increased output and lowered costs, making products more accessible to the general public. Today, assembly lines are a fundamental aspect of modern manufacturing.
