Abstract: Because of the complex nature of Enterprise Resource Planning (ERP) systems by way of integration of various business processes and activities across multiple divisions and functions of an organization, the issues of selection of right ERP system to suit the organizational requirements and its implementation to achieve proper synchronization stand as challenging ones in managing ERP projects. Several studies derived critical success factors for the success of ERP systems. This study attempts to measure the success as experienced and expressed by pure technical people like project leaders and managers who actually monitor, analyze and manage ERP systems in organizations. A survey was conducted around four big software companies which are agressively dealing with ERP solutions and the feedback of their technical people was collected and analyzed. Statistical factor analysis was carried out to identify major and essential factors that influence the phases of selection and implementation of ERP systems in organizations.
