A Methodology for Safety Case Development

A safety case is a requirement in many safety standards. Explicit safety cases are required for military systems, the off shore oil industry, rail transport and the nuclear industry. Furthermore, equivalent requirements can be found in other industry standards, such as IEC 1508 (which requires a “functional safety assessment”) the EN 292 Machinery Directive (which requires a “technical file”) and DO 178B for avionics (which requires an “accomplishment summary”).
