摘要：

Hazard Analysis and Risk Assessment (HARA) is a critical systems engineering and safety activity used to ensure a safe environment for personnel and hardware. At TIO we tailored the Atlassian Jira tool and third-party app SoftComply Risk Manager to provide a collaborative environment with subsystem teams in order to develop a comprehensive HARA process, starting with hazard identification and assessment and continuing through reassessment after mitigation. The paper shows how the tool was initially created for the Telescope Structure (STR) team to facilitate collaboration with the National Astronomical Observatory of Japan (NAOJ) and Mitsubishi Electric Corporation (MELCO) and has since expanded to all other subsystems as well as to the system-level, capturing intersystem hazards. From the system and subsystem HARAs, risk reduction actions are identified and if safety functions are used as a mitigation, they are described in terms of functional safety actions and associated SIL ratings. This overall HARA process provides TIO with a comprehensive overview of all Observatory hazards and the status of the development and implementation of their mitigations thanks to the Jira and Risk Manager dashboards, risk matrix, and risk table views.
