The information system maturity means that the enterprise has an integrated development process to manage information system. Using tightly alignment with the business strategy, the information system can get more performance results. In this article, we use the indicators from Information Technology Portfolio Management to evaluate the information system maturity, and try to find the organizational factors that influence it. With previous indicators and factors, we developed a questionnaire to mail the IT executives of 997 enterprises including the public as well as the small and medium companies. Finally, we got 148 valid questionnaires.
After analyzing the retuned data, we found some factors significant influence the information system maturity. These factors included the annual budget of IT department, the set-up period of IT department, the support of CEO, the information system development ratio between outsourcing and in-house development.
