In its efforts to modernize, reduce costs, and improve efficiency, the Department of Defense (DoD) has implemented strategies to improve its acquisition of goods and services. Indefinite-delivery/indefinite-quantity (IDIQ) contracts are being widely used within this context because of the flexibility they permit the contracting agency. This study presents findings from original quantitative and qualitative data generated by a survey of professional services industry firms experienced with the IDIQ contract vehicle. Based on our review of the literature and our survey results, we present a summary of the benefits of IDIQ arrangements and identify ways to improve IDIQ contract efficiency, while potentially enhancing competition. The objective of this report is to provide a better understanding of how the DoD can leverage the advantages of IDIQ contracting to improve efficiency and achieve cost savings in its acquisition of essential services.
