The SCSC Safer Complex Systems WG builds on the IET/RAE work already done in this area. 

Mission Statement

To produce practical guidance on developing, managing and assuring safety of complex systems throughout their lifecycle

Guidance Document

The latest draft of the Guidance - please note this is not for general distribution.

Statement of the Problem

• It is acknowledged that complex systems are becoming more prevalent with more opportunities to cause harm
• There are also new complex systems arising from using combinations of existing systems and services which are then used for safety purposes 
• Complex systems are not sufficiently addressed in current safety management practices and standards
• In particular, complex interactions and emergent behaviours are not currently assessed and managed sufficiently
• There could be benefit in developing new analysis, tools and techniques to manage complex system risks
• There are clear business and societal benefits, in terms of reduced harm, reduced liabilities and improved business efficiencies, in improved management of complex systems risk

WG Operation

We meet every 4-6 weeks via Zoom. New members are always welcome.
