For the effective use of the acquired or existing information system (IS) at the enterprise it is necessary to solve the problems relatedto an assessment of the IS quality. The information system is represented as a set of the functional components therefore it is necessary at first to evaluate quality of each of the components, and then get an integral assessment of the entire system. Quite tricky in the processes of IS quality assessment is the ambiguity of existing methods of formation the set of IT-indicators, most adequately characterizing the current state of functioning of the IS. It is necessary to define quantity and the list of IT-indicators (representative selection) which can be used to evaluate the quality of information systems in the enterprise to ensure the accuracy and veracity of quality assessment of IS. For formation of such selection it is offered to use an expert method. Expert's task is to select the criteria for the assessment quality of IS components, the formation of a representative selection of its indicators that best describe the real state of the information system at the enterprise, establishment of weights for IT-indicators, i.e. the importance of each IT-indicator to assess the quality of entire IS. The implementation of such actions, taking into account the recommendations of existing standards and using the method hierarchies’ analysis, are considered.
