A comparative study of the impact of ERP systems implementation on large companies in Slovakia and Slovenia

Abstract

Based on a literature review, it can be stated that there had been very little research published focused on enterprise resource planning (ERP) systems post-implementation period. This paper tries to contribute to filling in this gap in theory. The aim of this paper is to analyze whether a significant difference in the impact of ERP systems implementation on overall IS/IT costs can be found, as well as on the proportion of the IT/IS costs attributed to IT and other departments, on efficiency as profitability, on effectiveness as productivity, and on the availability of IS/IT services. The research is based on data from large Slovak and Slovenian companies. The models control for the extent and successfulness of the ERP system implementation and for the IT focus of the company. © 2011 Springer-Verlag.
