The problem of improving quality of work of a complex system, depending on system components that have the greatest influence on its performance is being analyzed in the paper. The author justifies the urgency of solving the problem of determining the critical elements of the system under certain probabilistic performance of their work. The probable model of information management system is considered, the effect of checking procedures at different stages of the management cycle is investigated. The article discusses an approach to the definition of critical components of information management network in view of checking its parameters at different stages. The sensitivity of the probable error-free system operation in relation to the probabilities of stage checking is adopted as an indicator of the criticality. Finally, a numerical example of the sensitivity calculation of probable error-free system operation in relation to the probable checking of stages based on the proposed model is submitted.
