First, the direct economic benefit evaluation refers to the comparison between the cost saved by computer management and the depreciation and operating expenses of one-time investment (including software and hardware investment) during the implementation of MIS. The application of management information system increases investment and some expenses, but it can reduce management personnel and reduce wages and labor costs. By realizing management modernization, saving material consumption, reducing cost consumption, reducing inventory funds, saving management expenses, plugging fund loopholes, etc. Scientific planning and decision-making can bring more inestimable economic benefits.
Second, indirect economic benefit evaluation refers to the evaluation of the benefits that enterprises can achieve real-time and quantitative management and improve their competitiveness after running MIS in terms of improving management efficiency and centralized data management, as well as the timeliness and accuracy of data transmission after establishing a network system. Mainly manifested in the comprehensive economic benefits brought by improving the overall management level through management means. Such comprehensive benefits often take some time to be reflected. The more advanced it is, the more obvious the effect will be, which will have a qualitative and strategic impact on enterprises. Mainly reflected in enterprise management automation, modernization of basic data, rationalization of management system, scientific management decision-making, optimization of management effect and so on.
(2) However, because information system engineering is different from general engineering, its investment cannot be a one-time investment, nor can it just be an investment in hardware. With the construction and operation of the system, there will be a series of inconspicuous expenses (such as development expenses, software expenses, maintenance expenses, operation expenses, etc.). ), and the proportion of these expenses is increasing. Then, the effectiveness of the information system is strongly delayed, correlated and unclear. The benefit of the information system will only happen after the system is completed and used for a long time. The benefit of the information system is closely related to the management system, management foundation, user's enthusiasm for use and user's technical level.
