Study on Evaluation Method of Enterprise Information System from Complex System Perspective

When an enterprise information system develops into the stage of being a complex system, the relatively delayed evaluation process will result in a low success rate of information system development projects. In this article, we analyzed the characteristics of evaluation process for information system projects, studied the evaluation methodology of information systems. Based on our studies, we proposed to evaluate the information system using from qualitative to quantitative methodologies at different stages of the whole development process, guided by the theory of open complex giant system. At different stage, we should calculate expert weights according to different evaluation focus. Lastly, we illustrated the whole evaluation steps. Our proposal will improve the efficiency and accuracy of the evaluation results, which is very important to guide the information system development.
