The call for poster abstracts for SSS'20 (11-13th Feb 2020 in York, UK) is now open. There will be two poster sessions at SSS'20; for those who have not done one before posters are a great way to present and discuss new work in a more informal setting.

Seminar - Evolution of Assurance Case Practice

On April 4th in London, the SCSC held a 1-day seminar on the future of assurance and safety case practice. This looked at new thinking in the automotive and civil aviation sectors and new developments such as SACM and Dialectic arguments. It also examined what a safety argument for an autonomous system might look like. Selected slides are now available on the event page.

Safety-Critical Systems Symposium SSS'19

The 27th Safety-Critical Systems Symposium (SSS'19) was held in Bristol, UK at the Bristol Marriott Royal Hotel (5th to 7th February 2019). #SSS19
The proceedings from the event are available at SCSC-150. Selected slides from this event are being made available under Past Events, SSS'19 as they become available.

Data Safety Guidance

The PDF of the new Data Safety Guidance document (V3.1) SCSC-127D is available to buy in hardcopy from Amazon or for free download. During 2018, feedback was received from four data safety courses and the application of version 3.0 of the Guidance to a real aviation problem, involving the safety of Unmanned Air Vehicles. As a result of this feedback, a number of clarifications and usability enhancements have been incorporated within the document. However, all paragraph numbers remain consistent with version 3.0. This release should therefore not be seen as a new version of the Guidance, but rather as an improved version of 3.0.

Autonomous Systems Guidance

The Safety of Autonomous Systems Working Group [SASWG] has published a document representing the first step towards establishing Recognised Good Practice for safety assurance of autonomous systems.  This document, Safety Assurance Objectives for Autonomous Systems, is available at SCSC-153.

Seminar - COTS, Legacy and Reuse

This seminar was held on 6th December in London and featured seven talks from acknowledged experts in the reuse of existing components, be they COTS, SOUP or other legacy items when an assurance claim for the overall system or service must be made.

Selected slides from this event are now available.

Slides from Past Events
Please note that slides from events (seminars, tutorials, etc.) are usually available on the event page after the event has taken place.
