In this paper we address a question highly relevant for many companies developing and implementing ERP or other software internationally. These companies have to integrate subsidiaries all over the world by using standard business processes implemented within the software, while at the same time take care of country-specific and other local requirements. The paper presents a framework of three different strategies, evaluates these strategies, and reports case study results that allow the comparison of these strategies. It is shown, that these strategies are not only relevant for ERP projects, but also for other software projects, especially global e-commerce projects.
