The ASAP (Accelerated SAP) methodology is used as the SAP implementation reference model in this study as most of the companies implementing SAP use ASAP methodology. In a study of articles on software implementation effectiveness, more than 30% of projects were perceived to have failed because of a lack of effective project planning, while 10% were perceived to have failed because of technology-driven causes. Content analysis of articles reporting SAP implementations of six companies from all over the world have been done. Four of these companies had a successful SAP ERP implementation and the other two were failures. Sustained executive management support and their ownership of the implementation, project team composition and good project management especially pertaining to process design, testing and training of the end users are the most important factors contributing to the success of SAP implementations in most organizations. Due to long time, cost, and be short of sustained management support / contribution and user involvement / training and testing are seems to be the factors contributing to the success/failure of SAP implementations in most organizations.
