The paper outlines the implementation of HRA in the framework of the IT-department of a major Swiss bank. The applicability of HRA techniques is shown by the case studies “Patch Management” and “Hardware Monitoring” which also include error probability assessments. Finally, a compilation of six case studies applying eight selected HRA techniques judges their practicability and usability. It is concluded that THERP and ASEP are the most appropriate techniques for analysing tasks in system monitoring, testing, and operation. HRA techniques based upon PSF are of limited practicability.
