In order to improve profitability a firm wants to achieve economies of scale. Which strategy best supports that goal?

Using the same equipment for all products can lead to inefficiencies, as different products may require distinct processes or machinery for optimal production. This approach can hinder specialization and reduce the potential for economies of scale since it does not exploit the advantages of focused production.

While general machinery allows for flexibility in production, it typically does not enable the level of efficiency or cost reduction associated with a product-focused operation. Flexibility may lead to slower production speeds and increased handling times, which can prevent the firm from achieving the significant cost savings that economies of scale provide.

A process layout is designed for flexibility and is typically used in environments where a variety of products are manufactured. However, this layout can result in increased movement and handling costs, which detracts from achieving economies of scale. In contrast, a product-focused operation would utilize a more efficient layout tailored for high volume production of fewer products.
