Final answer:
Assembly lines have a positive effect on flow time with large quantities, as they allow for more efficient and faster production. The use of assembly lines in manufacturing enables workers to specialize in specific tasks, increasing speed and quality of production.
Step-by-step explanation:
Assembly lines have a positive effect on flow time with large quantities, as they allow for more efficient and faster production. The use of assembly lines in manufacturing enables workers to specialize in specific tasks, which leads to increased speed and higher quality production. The Ford assembly line, for example, helped reduce labor costs and increase efficiency by dividing the production process into simple and repetitive steps.
