A safety analysis process and system are disclosed. The safety analysis evolution includes four phases: safety program definition, detailed safety analysis, safety disposition, and sustained safety engineering. In the safety program definition phase, a safety program is thoroughly defined through the generation of system safety plans and the establishment of the safety team. In the detailed safety analysis phase, the system is thoroughly analyzed using a systematic analysis approach while all engineering data is captured in the unified hazard tracking database. In the safety disposition phase, the safety posture is formally disclosed to safety review officials and operational safety precepts are generated. In the sustained safety engineering phase, the safety efforts are maintained, including maintaining the hazard tracking database and assessing the safety impact of reported problems, proposed engineering changes, maintenance changes, and incident reports.
