In order to evaluate safety or risk on today's highly integrated and complex systems, system safety must become an active participant in the requirements capture and validation process.?Application of requirements-based processes such as SAE ARP4754, RTCA DO-178, DO-254, and MIL-STD-882 software safety are used as primary mitigation for systemic failures within these highly integrated and complex systems.?To support these processes, safety assessments can be used to establish safety specific requirements and also identify functional and design implementation requirements that are used to comply with those safety-specific requirements.?This workshop will explore the different "safety requirement" definitions used within industry, discuss pros and cons of each definition and its usage, and demonstrate how the Functional Hazard Assessment (FHA), Fault Tree Analysis (FTA), and Functional Failure Mode and Effects Analysis (F-FMEA) can be used to define safety requirements and serve as supporting rationale.?Using these same analysis techniques in support of safety requirement validation will also be demonstrated.
As a caveat: this course will be limited to use of safety assessments and analyses to define requirements.?It is not a workshop on how to write "good" requirements from a systems engineering perspective.?Also, the workshop does not venture into the use of "model-based development techniques" to define safety requirements.
