What is the value of an IT e-procurement system?

E-procurement is gaining in popularity in business practice and its benefits encourage its adoption for a variety of areas, including IT (Information Technology) purchases. The problem with assessing the value associated with e-procurement has been addressed by researchers and practitioners, but a clear methodology to determine the benefits related to e-procurement adoption is still missing, especially for IT. This paper defines e-procurement and identifies the six most significant drivers for e-procurement adoption, which are the pillars of the proposed value assessment methodology. The authors have also applied the developed methodology to real cases in order to verify its validity and robustness. Finally, although the developed model takes into account the peculiarities of IT purchases, it also raises more research opportunities for other purchasing categories.
