This chapter describes the origins and history of the safety case approach. In particular, it describes how there has been a shift in emphasis in many industrial sectors from prescriptive regulation to a safety case regime. After the basic concepts and structure of safety cases have been explained, the chapter introduces the Goal Structuring Notation (GSN) as a typical means of presenting explicit structured arguments. A number of foundational concepts are also discussed-such as the nature of the arguments required in typical safety case, the challenge of evaluating safety cases, and reasoning about safety case confidence. Empirical research on the use and efficiency of safety cases is scarce. However, the chapter presents some of the criticisms and typical limitations presented in the literature concerning the safety case approach. Finally, the chapter concludes by discussing the complementary relationship that can exist between (compliance to) safety standards and the use of safety cases within regulation.
