    (09/16/2013) Dimakopoulou, Andriana G.; Athens University of Economics and Business, Department of Management Science and Technology; Doukidis, Georgios; Tsekrekos, Andrianos; Georgopoulos, Nikolaos; Gritzalis, Dimitrios; Poulymenakou, Angeliki; Voudouris, Irini; Pramatari, Katerina
    Real Options theory has been acknowledged for its significance and exploited in the IS field as a dynamic approach for the assessment of information technologies with high levels of uncertainty and irreversibility. However, there has been very little research on how the use of real options in IT capital budgeting affects managerial behavorial decisions. To address the above gap the present doctoral thesis develops a model drawing from Real Options theory, IT innovation firm adoption theories and IS classification frameworks with the aim to study the impact of Real Options on IT investment decision making process. The thesis empirically examines the developed model and applies it to the case of RFID technology. Based on an exploratory phase comprised of three case studies and a confirmatory phase including one pilot and two field studies and through the exploitation of first-generation (e.g. multiple regression, ANOVA) and second-generation statistical methods (i.e. structural equation modeling and confirmatory factor analysis) main results include the following. Although real options in IT projects affect managerial investment decisions, their impact is significant only in specific and not in all IT project types. In particular, this impact is strengthened for family, supply chain and strategic IT applications than for standalone, internal and transactional IT applications respectively. In addition, this study shows that recognition of growth options mediates the effect of specific organizational and technological parameters (e.g. innovative capabilities of an organization, sustainability of the technology investment impact) on the perceived IT project value of returns. The above findings have important research implications concerning several research streams such as: Real Options, IT investment evaluation and IT innovation adoption. The above findings have also important practical implications. Managers are suggested to embed real options reasoning in their investment decisions. In addition, IT suppliers and developers are recommended to design IT products with attributes which can trigger real options generation in order to affect managers' perceptions towards the value and the use of these products.
