What production method does ABC use for its standard concrete?

• A. Flow production to achieve economies of scale.
• B. Batch production to manage various inputs.
• C. Job production for customization.
• D. Flow production to achieve economies of scale.

Answer: (D)

Flow production is used for high-volume, standardized outputs, allowing tasks to move continuously through a streamlined process. For standard concrete, the product is homogeneous and can be produced in large quantities with specialized equipment, so running it on an assembly-line style flow maximizes throughput and lowers the cost per unit. This is how economies of scale are achieved: spreading fixed costs over many units and using continuous machinery to reduce per-unit labor and time. Batch production would slow things down with pauses between different mixes, and job production would be for customized orders, which isn’t the case with a standard, uniform product like concrete. That’s why flow production aimed at economies of scale is the best fit.
