Information systems evaluation: Navigating through the problem domain

Information systems (IS) make it possible to improve organizational efficiency and effectiveness, which can providecompetitive advantage. There is, however, a great deal of difficulty reported in the normative literature when it comes to theevaluation of investments in IS, with companies often finding themselves unable to assess the full implications of their ISinfrastructure. Although many of the savings resulting from IS are considered suitable for inclusion within traditionalaccountancy frameworks, it is the intangible and non-financial benefits, together with indirect project costs that complicate thejustification process. In exploring this phenomenon, the paper reviews the normative literature in the area of IS evaluation, andthen proposes a set of conjectures. These were tested within a case study to analyze the investment justification process of amanufacturing IS investment. The idiosyncrasies of the case study and problems experienced during its attempts to evaluate,implement, and realize the holistic implications of the IS investment are presented and critically analyzed. The paperconcludes by identifying lessons learnt and thus, proposes a number of empirical findings for consideration by decisionmakersduring the investment evaluation process.
