* The Post Office Horizon system would not normally be regarded as a safety system, yet it is a computer-based system that has indirectly led to widespread harm.

* The ongoing public enquiry has raised important legal, ethical and technical concerns. Problems highlighted include: sub-postmasters could not see what was going on (for example, figures changed remotely without sub-postmaster knowledge), poor quality coding and lack of both audit and fault logging.

* The SCSC fully supports the public enquiry and other investigations, and we agree with professional computer bodies (e.g. the British Computer Society) that there should be a review of how computer-based system evidence is treated by the courts.

* We will look to adopt relevant recommendations and encourage our members to do the same once the enquiry and investigations conclude.

* We propose that organisations relying on computer-based system evidence in court should, where challenged, be required to justify that the system, including aspects such as hardware, software, data and service delivery, is reliable. Furthermore the evidence should be shown to be trustworthy. The justification should also show appropriate confidence in use, including in the way that reported problems are managed. Courts should not accept evidence relating to the computer-based system without this justification.

* Where there are disputes involving computer-based systems there must be fair treatment; i.e. where relevant, there must be access for both sides to technical experts who in turn must be given access to appropriate software and data.

* Post Office Horizon is an example of how systems, organisations, agreements, people and processes came together within a delivered service to result in indirect but severe harm. We suggest that the SCSC Service Assurance Guidance could be useful in such situations to reduce risks.

* We will extend the remit of the SCSC to cover any computer-based systems and services which could cause harm. This will include harm in the wider context of the system including all stakeholders, the environment and consequential harms, not just harm caused directly by the system or service itself.

Note: Here “computer-based system” includes aspects such as hardware, software, data and service delivery. 

Microsoft is opening a new office in London dedicated to artificial intelligence (AI) research and development: https://lnkd.in/e7BVeV-N
This technology is going to impact us in so many ways - the SCSC will look at some of the safety implications in a series of seminars this year. The first seminar looking at frameworks is on 25th April: https://scsc.uk/e1081

Applications for the IET Young Woman Engineer (YWE) of the Year Awards are now open, https://youngwomenengineer.theiet.org It would be great to see a Safety Engineer win this!

All the 1-day seminars this year will have an AI theme reflecting the importance of this rapidly evolving technology. The first is on April 25th and looks at frameworks for AI, subsequent seminars look at building systems with AI and operating them.

We had a fantastic SSS'24 with record attendance. The talks were excellent, and the Safe AI panel generated a lot of interest. Over the next couple of weeks we'll be posting photos and videos from the event.

Only 1 room left in the SSS24 symposium hotel for the Tuesday night! https://scsc.uk/e1007
Please book on quickly if you want it!

The Japan air crash in which 5 people died is obviously a tragedy for those affected, but it is also a success in that all the passengers and crew of the Airbus A350 (379 in total) all escaped, https://www.bbc.co.uk/news/world-asia-67870119. This is astonishing as there was little time to exit and some of the systems and escape routes were unusable. However it just shows what trained crews can do, and also passengers when they comply with instructions. We await the first official reports with interest.

We hope you have a really good break over the festive season. This year seems to have been busier than ever with new challenges so some rest and relaxation is definitely needed! However the SCSC remains open over the holiday period and the web site is able to take bookings as normal.
