The development of the modern society, including information technologies, makes new demands for the organizational management in the social and economic systems, related to the necessity of constant adaptation to the changing environment in the presence of a number of factors of internal and external effects, taking into account the conservation of competitiveness in the market of IT-services. The article describes a new class of the systems of organizational management, operating under structural uncertainty, based on the prior art developments in the field of control systems with variable structure. The paper considers the specification of a new class of the systems in relation to the management of IT-services, which includes built-in optimization system, which allows modification of any components and links of the control system with previously unknown changes in the external and internal factors. The objective of optimization system is to maintain a competitiveness of the provider of IT-services in conditions of the controlled and uncontrolled disturbances. The optimization criteria — cost-effectiveness of all the IT-service providers, as well as a restriction on the criterion — its threshold value defined by IT-service market, are formalized. The particular example shows the feasibility of the introduction of the optimization system based on the principles of continuous improvement of services in the existing IT-infrastructure of the company. The efficiency indicators of the IT-infrastructure of the company before and after the implementation of the optimization project, proving the effectiveness of the proposed system of organizational management, are given.
