A factory is a large building or facility where goods are manufactured or assembled. It typically contains machinery, tools, and workers who collaborate to produce products on a large scale. Factories can produce a wide range of items, from automobiles to clothing, and often use assembly lines to streamline the production process. Factories play a crucial role in the economy by creating jobs and contributing to the supply of goods. They can vary in size and complexity, with some focusing on mass production while others may specialize in custom or small-batch manufacturing. The efficiency of a factory often depends on its technology and workforce.
