Enterprise resource planning (ERP) is an enterprise-wide information system designed to coordinate all the resources, information, and activities, it provides a unified enterprise view of the business for all functions and departments, and also an enterprise database for all business transaction, but despite all the benefits they are also seen as an expensive, profoundly complex, and notoriously difficult to implement because it is different from other IT systems. There are as many reasons for successful ERP implementations as there are for failed projects.It is really difficult to measure the success of a project of implementation because each organization can look at the success of ERP implementation differently. It is important for the organization to have as much information as possible before embarking an ERP project, and also respect some critical factor for the success of the project. Measuring and knowing the importance of each factor will help an organization to make the right decision, at the right moment. This survey examines and also tries to determine the necessary critical success factors (CSFs) in implementing Enterprise Resource Planning (ERP) systems and also try to examine the impact of this technology on the performance of the whole organization. We were able to identify six critical success factors by the survey. They are (1) Infrastructure, (2) Business process management, (3) Project management, (4) Project team, (5) Culture, communication, and change management, and (6) Training and education.
