This work presents basic elements of availability management methodology in complex technical systems according to the business and user perspectives. The methodology primarily relates to Information Technology (IT) systems, and the presented availability perspectives are based on parameters resulted from the exploitation conditions, according to analysis of the Tax Administration Information System of the Republic of Serbia - DIS 2003. The result of the implemented technology enhances the availability level through the clear identification and elimination of critical elements that affect the stability of IT infrastructure and ensures a continuing service provided by the system. The criteria of the optimization applied within the implementation of the availability enhancing process present a relation between the cost price of service provided by the system and expenditures of investments in improvements. Considering the established business requirements through the system, the availability management process should be given an appropriate level of service.
