Hi Simon, thanks for your comprehensive explanation regarding those processes. Is it possible for you to support this issue with some examples? Especially in Aerospace industry, certification guidelines still state safety requirements by taking Fault/Failure approach into the consideration. For showing compliance, the applicant must perform some fault/failure analysis so that it can show compliance to those safety objectives. In this manner, how can we integrate STPA, namely systems theory into the traditional fault/failure approach? It would be great to see some examples which show both methods covering their missing points.
Hi Oguzhan, thank you for your kind message. Unfortunately, I don’t have any examples I can share, though I’m happy to answer your questions on a call (I’ll send you a link to book a time that suits you). The challenge with Civil Cert is that they must have a fault / failure focused answer, which STPA can support, but Cleary there will be things that STPA finds that are not failures... so those results and requirements will still need to be documented and communicated, it’s just they won’t fit into the “round hole” as they are “square pegs”.
