Vertical integration

Explanation:

"Vertical integration is a strategy whereby a company owns or controls its suppliers, distributors, or retail locations to control its value or supply chain. Vertical integration benefits companies by allowing them to control the process, reduce costs, and improve efficiencies. However, vertical integration has its disadvantages, including the significant amounts of capital investment required."
