Enterprise Resource Planning (ERP), an information system attempts to integrate all departments and functions across a company onto a single computer system. Little research, however, has been conducted on collective integrated implementation framework and operatinalization of ERP system. The current research seeks to integrate a prominent model of information system implementation to develop holistic approach to ERP implementation. Using ERP implementation model and Critical Success Factors (CSFs) , and integrated ERP implementation framework is proposed. This framework comprises of two important phases of ERP systems in the organizations, namely implementation processes and CSFs. Each phase comprises of four stages in which the process follows and then the success of ERP implementation is measured by project outcomes and organizational impacts. The process stages and critical success factors are then empirically tested.
