Many organisations perceive enterprise resource planning (ERP) as a potential, vital and crucial solution to their businesses to gain efficiencies and be competitive. ERP implementation can reap enormous benefits, or it can be disastrous for organisations that fail to manage the implementation process. The adoption of a new ERP system is a highly complex process, and it is not as easy as people imagine, it is a challenging task that requires rigorous efforts, a careful thinking, and proper planning; also it demands to have a detailed analysis of such factors that are critical to the implementation. The field has invoked immense interest in the research community, and several previous studies have tried to assess the success of these systems and highlight the CSF's based on some theoretical models. A better understanding of the CSFs will shrink the field of failure and help the practitioners and managers to improve the chance of success. The purpose of this study is to form a basis for future studies which may help future ERP initiatives to achieve greater success and less failure, it seeks to investigate the critical success factors of Enterprise Resource Planning (ERP) implementation, and then determine what factors are the most highly correlated with the success of ERP projects. To evaluate each element, we used a statistical data analysis. The approach used in this research consisted of both a quantitative and qualitative analysis, the study consisted of a literature review. The data collected were analyzed, and several conclusions were drawn.
