The invention discloses an information system engineering supervision enterprise service management system. The system comprises a project activity module, a user resource authorization module, an attachment management module, a workflow module, a timing module and a rule management module, automation of the whole process of information system engineering supervision service activities is achieved, and key steps of all project execution can be achieved through the system. Moreover, the system is developed by combining characteristics of the supervision industry, and is suitable for domestic information system engineering supervision projects, thereby measuring and realizing standard reaching of information system supervision services. Therefore, three-dimensional accurate guidance and accurate control of the project in the whole supervision project period and managers are realized, the supervision project management efficiency and accuracy are improved, and the management cost is reduced.
