 The make-or-buy decision refers to the firm's choice to make its necessary inputs itself or buy them from outside suppliers.

Most personal computer manufacturers, for example, have chosen to buy disk drives, USB ports, and microprocessors from outside suppliers. By so doing, they avoid the risk of product obsolescence and the large research and development expenditures needed to stay on the cutting edge of each of the technologies embedded in the component parts of personal computers or when inflation and exchange rates are fluctuating.
