product-line expansion(Expanding a product line is an important growth strategy for small businesses that want to increase revenue or market share. A product line is a group of products or services in the same category, such as pet foods, engineering components or IT support services. Product-line expansion can take a number of forms, including new versions of an existing product, upgrades to existing products or completely new products. | Alexander Demidov)
economy of scope(Economies of scope are conceptually similar to economies of scale. Whereas economies of scale for a firm primarily refers to reductions in the average cost (cost per unit) associated with increasing the scale of production for a single product type, economies of scope refers to lowering the average cost for a firm in producing two or more products.
