Since modern buildings are complex facilities, the facility managers have to outsource many activities to other specialized companies. In this context, decisions to make or to buy become of key importance to facility management companies. This present paper proposes an approach for making a reasonable decision to make or to buy based on the use of data envelopment analysis (DEA).
