 Safety-Critical Systems Club 
 For Everyone Working in Systems Safety

The SCSC is the UK's professional network for sharing knowledge about system safety.  It brings together engineers and specialists from a range of disciplines and industries working in system safety, academics researching the arena of system safety, providers of the tools and services that are needed to develop the systems, and the regulators who oversee safety.

The SCSC provides seminars, workshops and tutorials throughout the year, with a three-day annual Safety-Critical Systems Symposium in February.

The 31st Safety-Critical Systems Symposium was held at the Principal Hotel in York UK from 7th to 9th February.

All of the papers from the proceedings, presentations and videos of the presentations are available now at'23.

This was an extremely successful event with over 140 participants, most of whom were attending in person.

…thank you for a fantastic Symposium over the past three days - a really enlightening experience that has prompted a few different ways of thinking.

Thank you both for a very successful conference. Every year is getting better, and better!

It was great to attend a well-run SCSC symposium again.

  • Nikita and Zoe Garstang are also involved in our Safety Futures Initiative (SFI) for younger members and STEM outreach.
  • Recent presenters at SSS ’23, including: Catherine Menon, Gill Kernick, Laure Buysse, Carmen Cârlan, Doria Ramadan and Marea de Koning. (Catherine, as well as doing many other things, has also contributed to an industry guidance document being developed by our security-informed safety working group.)
  • Special mention to Yvonne Oakshott for her assurance work and long-time support of SSS, Katrina Attwood for editing Newsletters and Amira Kawar for past work on Steering Group and with the Data Safety Initiative.
  • All of those women who participate in the SCSC Working Groups, including WG leaders Sarah Carrington (SASEWG) and Philippa Ryan (SASWG).

We intend to publish a more comprehensive article for INWED (International Women in Engineering Day), which will include historical and international contributors to the field.
