Efficiency Implications of E-Procurement System Capabilities and Usage Behavior: Status Quo and Directions for Future Research

As the major Information System (IS) of procurement departments, e-procurement systems have already received a significant amount of attention by researchers. However, an integrated view on the efficiency implications of both e-procurement system capabilities and the corresponding usage behavior of purchasers from a welfare economics perspective is still missing. The work at hand closes this gap by providing the results of a comprehensive literature review aiming at the integration of related scientific findings. These results include the major processes typically supported by e-procurement systems, as well as a detailed view on efficiency issues of single system components. Based on a thorough discussion of these results, a number of efficiency measures, managerial implications, as well as a well-grounded agenda for future efficiency-oriented research are derived.
