A decision support framework for strategic purchasing

This paper illustrates that the make or buy is a strategic decision and has implications for the overall corporate strategy of the organisation by describing a model which involves analysing a number of strategic factors. In recent years, many companies have been moving significantly away from “making” towards “buying”.
