Definition of the System, Operational Design Domain, and Concept of Operation
摘要
This chapter consists of three section outlining how a description of a safety-critical system should be provided. First, we elaborate on how the Definition of the System (DoS) should be provided, ensuring a detailed description of the system for which the safety case is being presented. Next, we elaborate on how the environment surrounding the safety-critical system should be accounted for through a detailed description of the Operational Design Domain (ODD). Lastly, we outline how the Concept of Operation (ConOps) bridges the description made of the DoS and the ODD by addressing the different types of users and modes of operation of the system. By taking all these three aspects into account, a comprehensive description of the safety-critical system in its operational use should be accounted for.
