In the long-run a firm can amend its size and organization to violate demand conditions. In other words, in the long-run the firm can adjust its scale of operations or size of plant to produce any required output in the most efficient way. Thus, in the long run fixed factors can be altered. Management can be restructured to run a firm of a different size. Capital can also be used differently. In short, all factors are variable in the long run and therefore the scale of operations can be altered
