Global goals of IT-services supplier and consumer

Abstract

One of the important tasks for achieving global goals in the area of information technologies is the task of formulating a unified definition of information systems. Particular attention should be given to a clear awareness of the need to adapt typical functional tasks of information systems and information technologies that implement these tasks in accordance with special features of particular enterprises and organizations. The main problem of creating information systems is the proper organization of such sequences presenting data that would ensure the formation of a unified integrated information representation of the object or process required to achieve the pre-set information system goals. The solution of these problems has resulted in an approach to forming a representation of the functional structure of information systems as a set of interrelated cost effective IT-services, the timely provision and execution of which gives an efficient and high-quality activity of a controlled object and / or process. The paper proposes one of the ways for solving the problem of developing definitions of basic terms in the field of information systems and technologies that will allow to formulate and solve the problem of forming a unified coherent information representation of the object or automation process at a formal level. The main attention is paid to allocating an information systems macrodesigning problem as that of analysis and synthesis of a set of IT-services, which will allow consumers to increase revenue or reduce costs to implement automated processes with limited costs for development, implementation and support of IT-services.
