Expert evaluation of damage through enterprise information system failure

The article considers the problem of damage evaluation in case of failure of the information system. There have been analyzed the practical methods of assessing damage. It has been stated that the methods can reveal the dependence of the damage on the downtime of the information system, but they are unable to evaluate reputation, administrative or any other consequences. An algorithm is proposed by which specialists can conduct a comparative assessment of damage in case of failure of various information systems using expert information. Applying the proposed algorithm to different information systems, it is possible to determine the most critical systems and, on this basis, effectively plan operational impacts to increase the level of service availability.
