An Investigation of ERP implementation: : A Comparative Case Study of SME and Large Enterprises in Thailand

Implementing an ERP systemfor large enterprises (LE) is a challenge undertaking. Previous studies reported on various factors attributed to implementation failures in LE that are difficult to handle. Those are, for instance, inappropriately designed business processes, lack of clarity about changes, change management, communication issues, and poor project management. In Thailand, there are notable shortages of empirical case studies in the Information System field, research on ERP included. Our study serves as a source of empirical evidences showing how the implementation of ERP software were carried out in different manner in a case of SME and a large-scaled enterprise. We identified core activities and critical success factors that drive certain mechanisms during each stage of the implementation life cycle. The findings were based on a series of in-depth interviews with the case key informants. The insights gained fromthe analysis could assist project planning and decision making, and hopefully minimizing the chance of ERP project failure.
