Abstract:
Special-purpose information systems, i. e., systems in the field of ensuring defense capability, law enforcement, and security are not designed to generate income in monetary form, i. e., it is impossible to assess the effectiveness of capital and operating costs using profit and gross income values. Nevertheless, the state and functional customers as well as the operating organization face the task of objectively evaluating the cost effectiveness in one form or another. In this regard, to assess the effectiveness of capital and operating costs in relation to such types of systems, it is necessary to determine approaches to this assessment based on taking into account the consumer properties of an information system at all stages of its life cycle. The methods of calculating efficiency are proposed taking into account the degree of implementation of system requirements and processes for achieving the goals of the information system.
Keywords:information system, life cycle, capital costs, operating costs, efficiency indicator.
