Element 8 “Manage Life-Cycle Risk”. After the system is fielded, the system program office uses the system safety process to identify hazards and maintain the Hazard Tracking System (HTS) throughout the system’s life-cycle. This life-cycle effort considers any changes to include, but not limited to, the interfaces, users, hardware and software, mishap data, mission(s) or […]
Element 5 “Reduce Risk” is where Mitigation measures are selected and implemented to achieve an acceptable risk level. Consider and evaluate the cost, feasibility, and effectiveness of candidate mitigation methods as part of the Systems Engineering process and Integrated Product Team (IPT) processes. Present the current hazards, their associated severity and probability assessments, and
Element 4 “Identify and document risk mitigation measures” is where risk mitigation(s) is identified, and the expected risk reduction(s) of the alternative(s) shall be estimated and documented in the Hazard Tracking System (HTS). The goal should always be to eliminate the hazard if possible. When a hazard cannot be eliminated, the associated risk should be
Element 1 “Document the system safety approach” is where the Program Manager (PM) and contractor document the system safety approach for managing hazards as an integral part of the Systems Engineering Process. MIL-STD-882E “Standard Practice for System Safety” – Page 10 The approach should describe the risk management effort and how the
Element 3 “Assess and document risk” documents the severity category and probability level for a potential mishap(s) for each hazard. Each risk is assessed using the definitions in Tables 1 and Table 2 below from MIL-STD-882E. Standard: MIL-STD-882E “Standard Practice for System Safety” – Page 10 Severity Category To determine the appropriate severity category as
Risk Tracking (sometimes referred to as Risk Monitoring) is an activity of systematically tracking and evaluating the performance of risk mitigation actions against established metrics throughout the acquisition process and develops further risk mitigation options or executes risk mitigation plans, as appropriate. Its intent is to ensure successful Risk Mitigation and should be done as
System Safety is the application of engineering and management principles, criteria, and techniques to achieve acceptable risk within the constraints of operational effectiveness and suitability, schedule, and cost throughout the system’s lifecycle. System safety covers the entire spectrum of Environment, Safety, and Occupational Health (ESOH) considerations. It is an integral part of the Systems Engineering (SE) process
Risk analysis is the activity of examining each identified risk to refine the description of the risk, isolate the cause, determine the effects, aid in setting risk mitigation priorities. It refines each risk in terms of its likelihood, its consequence, and its relationship to other risk areas or processes. The analysis begins with a detailed
Risk Mitigation (it used to be called Risk Handling) is the process that identifies, evaluates, selects, and implements options in order to set risk at acceptable levels given program constraints and objectives. This includes the specifics on what should be done, when it should be accomplished, who is responsible, and associated cost and schedule. Definition:
A Risk Mitigation Plan Implementation is meant to ensure successful Risk Mitigation occurs and is based upon a program Risk Mitigation Plan (RMP). It should: [1] Determines what planning, budget, and requirements and contractual changes are needed, Provides a coordination vehicle with management and other stakeholders, Directs the teams to execute the defined and approved
