This document summarizes critical success factors for implementing an enterprise resource planning (ERP) system. It begins with an introduction to ERP systems and a literature review identifying top critical success factors. A company is evaluated at the pre-implementation stage to assess perceptions of the critical success factors. Top factors included top management support, user training, project management, and clear goals/objectives. The evaluation found no common understanding of the company's ERP strategy. Implementation approaches and additional influencing factors like business process reengineering and multi-site implementations are also discussed.
