SCSC - Group: Steering Group

SCSC Steering Group

The SCSC Steering Group (SG) exists to provide guidance to the Club's operations team on all aspects of the Club's activities and events.

The SG does not currently have a written constitution and consistent with the 'community' nature of the Club operates in an informal way to support the Club as effectively as practical.  Although the SG may make decisions regarding the operation of the Club, these should be interpreted as advice to the operations team who are responsible for their implementation. Members of the SG, or other Club members, may participate as volunteers in the implementation of Club activities but this does not indicate they are acting with any authority other than that delegated from the operations team.

The SG meets twice a year to discuss Club business.

Stephen Bull

Stephen is a Chartered Engineer with over 20 years of experience in development and assurance of safety critical systems in railway signalling, aviation and defence environments and is currently technical lead for the Rail team at Ebeni.

Stephen has developed safety cases for UK and international airports, and for multiple UK railway developments (including Network Rail and London Underground), taking a goal-based approach, focusing on what needs to be demonstrated, rather than rigid adherence to a particular prescription or structure. He always supports his safety cases with rigorous detailed analysis and evidence to back up the arguments made. He has a record of successful presentation to sceptical third parties (e.g. independent assessors and customer acceptance panels).

Stephen has worked on international research and development programmes in both aviation and rail industries: he produced the Consolidated New Approval Method for the EU-funded ASCOS Programme, which presented a goal-based method to streamline certification across the European aviation industry. He is also leading the assurance for the EULYNX programme, which is developing a standardised set of interfaces for railway signalling systems across Europe.

Stephen’s early career included software engineering (SPARK Ada and C), giving a valuable insight into successful safety engineering and safety management of software intensive systems.

Stephen takes an active interest in sharing with and learning from the wider safety critical systems community and has presented papers to SCSC and IET conferences. He is also a member of the SCSC Security Informed Safety working group.
