Vertical and Horizontal Integration

Vertical Integration
In microeconomics and management, the term vertical integration describes a style of growth and management control. Vertically integrated companies in a supply chain are united through a common owner. Usually each member of the supply chain produces a different product or (market-specific) service, and the products combine to satisfy a common need. It is contrasted with horizontal integration. Vertical integration has also described management styles that bring large portions of the supply chain not only under a common ownership, but also into one corporation.

Horizontal Integration
In business, horizontal integration is a strategy where a company creates or acquires production units for outputs which are alike - either complementary or competitive. One example would be when a company acquires competitors in the same industry doing the same stage of production. Another example is the management of a group of products which are alike, yet at different price points, complexities, and qualities. This strategy may reduce competition and increase market share by using economies of scale.
