Success is often defined as a favorable or satisfactory result or outcome. Since the objectives of an Enterprise Resource Planning (ERP) implementation project reveal exactly the states of an ERP system, which managers wish to realize, the knowledge of these objectives can indicate how outcomes of an ERP system execution must be measured in the ERP success analysis. This paper proposes a comprehensive framework for assessing the performance of an adopted ERP system. Based on the knowledge of ERP implementation objectives, the framework can systematically identify the appropriate ERP performance indicators, construct the performance indicator structure, and set up consistent evaluation standards for facilitating the complex ERP performance evaluation process. A real-world example demonstrates the feasibility of the proposed framework.
