Risk Assessment: Tools, Techniques, and Their Applications

15.2 Requirements of the Risk Assessment

Any assessment of risk requires an in-depth technical knowledge of the systems/processes being evaluated. The ability to define the system(s) affected as well as the response both with and without operator intervention is imperative to a valid assessment. Also important is the ability to recognize the adverse consequents in the event of a failure or misoperation of the facility and its component systems. If utilized to meet a regulatory requirement, any requirement of that agency needs to be identified and verified in the final product. Rigorous analysis and documentation of that analysis will make it more defensible as well as facilitating peer review of the final product. Peer review should be conducted on all risk assessments utilized for decision making.
