Developing Integrated System Safety Cases 
      using Goal Structuring Notation (GSN) 
       
      One-Day Hands-On Training Course 501 
      London: 5 May 2006 
      rcm2 limited, in conjunction with Origin Consulting 
        (York) limited, is pleased to announce this one-day hands-on training 
        course on System Safety Case development using the Goal Structuring Notation 
        (GSN) and ISCaDE (Integrated Safety Case Development Environment). 
      What is GSN?  
        GSN is a graphical notation used for presenting system safety arguments. 
        It offers an explicit means of representing the decomposition of safety 
        requirements into claims, and support for these claims from available 
        safety evidence. It is useful both at safety planning and the safety audit 
        phases of a project. 
      What is meant by Integrated Safety Case Management? 
        Integrated Safety Case Development and Management is about the use of 
        processes and supporting tools to demonstrate the linkage between different 
        elements of a safety regime. These include traceability between hazards, 
        causes and consequences, safety risk reduction and mitigation/control 
        measures, as well as the links to overall safety Goals (objectives) in 
        a structured way and within an integrated database environment. This enables 
        traceability of safety case arguments to hazard log information and to 
        certification requirements arising from standards.  
      Who is the course for?  
        Our course is suitable for those whose roles involve System Safety/Reliability 
        Management, Assurance and Risk Mitigation, Safety Engineering and Analysis, 
        Hazard Management, Compliance and Certification. 
      What will you learn in just one day? 
        This one-day course introduces the GSN method with two case studies and 
        one group exercise. The attendees are introduced to a GSN software package 
        (ISCaDE™ Pro) used within the day’s group exercises to develop 
        and capture GSN diagrams. In particular, attendees will be shown how it 
        is possible to explicitly link Goal Structures to existing safety documents, 
        requirements and safety standards (such as Defence Standard 00-56 Issue 
        3 and the HSE Railway Safety Case Assessment Criteria). 
      Who are the speakers?  
        Dr Saeed Fararooy is a Speaker on systems engineering, requirements 
        management processes and IT tools, whole-life system safety and reliability 
        (RAMS/Dependability) management and engineering. He is a practitioner 
        with rcm2 limited, a system safety/reliability solution provider to safety-critical 
        industries.  
      Dr Rob Weaver is an academic and consultant in the field 
        of safety-critical systems development and assurance. He has been involved 
        in the development of GSN over the last six years.
