"Standards We Love" by Heidy Khlaaf [PWLConf 2018]

Heidy Khlaaf explains how software in safety-critical systems is assured, verified, and governed by rigorous standards.

PWLConf 2018 Link: pwlconf.org/2018/heidy-khlaaf/ Slides / Captions: github.com/papers-we-love/pwlconf-info/tree/master/2018/heid… Standards We Love (for assuring and verifying safety-critical systems) Heidy Khlaaf, Research Consultant, Adelard LLP Safety-Critical systems are prevalent throughout our everyday life, from using electricity generated by a nuclear power plant to riding an airplane in order to attend your favorite conference. Despite the increasingly-complex software used in these systems, both the tech and verification communities are largely unaware of the issues, processes, and standards that govern them. This talk will provide an overview of safety-critical systems and how the software used is assured and verified up to standards that ensure our safety.
