Assembly line techniques are 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 taken to produce goods and increases overall output, making it ideal for mass production. The concept was popularized by Henry Ford in the early 20th century, particularly in the automotive industry. By breaking down complex tasks into simpler steps, assembly lines enable companies to produce large quantities of products, such as cars or electronics, while maintaining consistent quality and reducing labor costs.
