The SCSC ACWG has established a sub-working group to review the Goal Structuring Notation (GSN) standard [scsc-141B].
The activity will address updates to the modular notation, add notation for Argument Claim Points (ACP), add information on the relationship between GSN and SACM, consider notation additions for Dialectic arguments, and perform a general review.
This is an opportunity to address any user feedback on the current version and add topics for consideration in future versions. Please provide any feedback using the GSN Forum
The Safety Critical Systems Symposium 2021 will be held from 9-11th February 2021 in Bristol, UK.
An invitation to submit an abstract has been published

Many congratulations to all our winners!
Data can directly cause systems to behave anomalously (e.g. sensor data in the Boeing 737 MAX) or it can cause humans to take inappropriate actions leading to harm. On November 14th in London the event "Data Safety Evolution" was an opportunity to hear about the issues data can cause in safety systems and look at developments in the area. It will be useful for safety engineers and safety managers, across any sector that uses data in a safety context, i.e. most of us! Full details at: scsc.uk/e651
