Information Technology represents substantial financial investment for government organization. However, it seems that the real goal of IT investment, which is to make government more efficient, effective, and responsible through IT systems, has not been seriously aware of in the government organizations. As a result, despite of large investment in IT over many years, substantial benefits accrued to the work, such as process innovation and work efficiency, have not actually occurred. In this paper, it is argued that, since IT benefits will not be realized without any effective benefits realization efforts, it is needed in IT evaluation to put more emphasis on the efforts. Therefore, it is suggested that appropriate IT evaluation can possibly work as a guideline for deriving the desired benefits through the IT investment. In this study, some of the well known approaches were reviewed about what IT evaluation and IT benefits realization efforts should be. Current evaluation method was analyzed from the perspective of benefits realization. On the basis of the analysis, this study leads to suggestions that improve the current ways of evaluating IT performance, helping government focus on realizing practical IT benefits at work.
