It can be used in a manner to reduce average costs where the businesses can achieve full benefits of economies of scale with the proper management of material and expenses, where internal abilities are fully exploited by using better technology, different types of investment products, innovation and specialization in commodities production to make use of new resources to lower the overall costs.
Traditionally, the level is defined as the lowest stage at which the long-term average market value of goods manufactured can be minimized.
