The method of selecting a variant of the construction of information and telecommunication systems

The article is devoted to the description of the method of choosing the option of building an information and telecommunication system (ITCS). The authors discuss the general methodological approach to the selection of solutions to system integrators of building ITCS taking into account their characteristics, principles, and conditions of the build. The method of choice of variants of building an ITCS includes two interrelated techniques: the methodology to assess the effectiveness of ITCS and the method of selection of variants of ITCS. The authors describe the methodology for assessing the effectiveness of the ITCS developed in previous publications. The method of choosing the option of building ITCS takes into account the contribution to the effectiveness of the relevant organizational system, technical feasibility, and risks of development and application. A list of specific performance indicators for each of the three groups of generalized performance indicators (contribution to the efficiency of the organizational system, technical feasibility, and risks) is proposed.
