Over the last few decades, not only organizations but also Higher Education Institutions should be more responsive to the demands of the changed global business environment and improve their effectiveness. Our motivation to write this paper is to assess the implementation of an Enterprise Resource Planning (ERP) system in higher education and their associated benefits, with a focus on students' performance when applying an SAP solution. This paper analyses the accuracy of undergraduate students, focusing primarily on the concept of self-assessment as they predict and evaluate their own performance relative to their externally assessed achievement. In the pre- and post-examination predictions the higher achieving students seem to predict and evaluate their examination results more accurately than their lower-achieving fellows. Although a gender gap cannot be found in self-estimation, we found substantial differences by comparing the selected language. Foreign students seem to overestimate their own examination performance to a greater degree than Hungarians do. Consequently, our results might allow decision makers to identify why self-assessment is important when implementing pilot ERP projects. The result of this study also provide evidence for groups of clients and other stakeholders in order to reduce failure in both higher education and business environment.
