    In the UK, GSN as part of Safety Cases have proven to be useful for providing objective safety evidence. [citation needed] A Safety Case is an ideal way to reflect the MBSE model, software use cases, safety architecture, safety critical functional behavior, safe states, and sequencing in the safety domain. Functional behavior is often better ...
