Enterprise Resource Planning (ERP) systems are important for all kinds of enterprises. The selection and implementation of such systems are very difficult and many projects do not meet their expectations. While large companies have financial and human resources to engage in such a project, the situation for smaller sized enterprises is different. They have only limited budget, human resources and experiences. Hence, this case study describes an EPR selection and implementation project at a small-sized enterprise by analyzing the selection and implementation procedure and its critical success factors.
