Abstract:
1. A method for determining a quality of an information technology (IT) system comprising a plurality of hardware units and software modules, the method comprising: calculating a total score value for the IT system from different score values ascertained independently of one another, wherein the different score values are measures for deviations of qualities of hardware units and software modules of the plurality of hardware units and software modules from first predefinable target values, wherein the total score value is a measure of a deviation of the quality of the IT system from a second predefinable target value, wherein the quality of the IT system includes a failure probability of the IT system, the failure probability of the IT system comprising the qualities of both the hardware units and the software modules, wherein the quality of each hardware unit comprises (1) a measure of severity of the hardware unit and (2) a number of error messages of the hardware unit, and wherein the quality of each software module comprises (1) a measure of severity of the software module and (2) a number of error messages of the software module.
