This paper presents the results of four cross-sectional surveys of the top 5000 largest corporations in Taiwan, undertaken in 2003, 2006, 2009 and 2012. We focus on a longitudinal study of the used or intended implementation of Enterprise Resource Planning (ERP) systems of firms to examine the “innovation diffusion” phenomenon and examine key management issues during the “ERP life cycle” phases. Our initial empirical analysis provides us with a number of interesting results. We find that the implementation of an ERP project entails an innovation diffusion phenomenon. Our analysis further shows that some important management issues deserve more attention during the life cycle of ERP projects. Based on our findings, practitioners, academics and entrepreneurs will benefit from this knowledge to prepare an effective management plan to increase ERP implementation success.
