How does mass production lower the cost of each item made?

Mass production lowers the cost of each item through the principle of economy of scale, where increasing production volume reduces the average cost per unit. This efficiency is achieved through several key strategies:1

• Division of Labour: By breaking production into specialized, repetitive tasks, workers can perform their roles more rapidly and with minimal unnecessary motion, increasing overall productivity.23
• Standardization: Using standardized, interchangeable parts ensures that components fit together without manual adjustment, which streamlines assembly and reduces waste.42
• Specialized Machinery: Investing in automated tools and transfer machines minimizes human effort, maximizes output per unit of capital, and ensures high precision and uniformity.52
• Systematic Planning: Detailed engineering of the entire production flow—from raw materials to the finished product—optimizes the balance between human labor and machinery, minimizing costs and lead times.52

By maintaining high volumes, manufacturers can spread fixed costs over a larger number of items, resulting in lower unit costs and making goods more accessible to the standard of living of the general population.42
