Abstract

As the integration of informatization and industrialization goes deeper in State Grid Jiangsu Electric Power Company, the lean management of O&M (operation and maintenance) of information system plays a more important role in the company’s production and management. On the ground of a full investigation of the current information system of the company, this paper has improved the model of business impact analysis (BIA) and, based on which, proposed a new method to classify O&M of information system. As proved in our practices in the company, the proposed model and method are efficient in controlling the cost of optimizing the operation of the information system, raising the efficiency of resource utilization as well as in improving the O&M management.
