1.1.1 Defining system scope
Assurance objective: Define the system boundary for the RAS.
Contextual description: It is important to be clear about what the system is for which assurance is being provided as anything that falls outside of that system definition will not be considered during the assurance process, with responsibility for its assurance lying elsewhere. It is particularly important for RAS whose behaviour is distributed amongst a number of entities, or where humans and machines are interacting that the scope of the system under consideration is clearly defined to ensure the completeness of the assurance activities. Where multiple interacting systems are used, a decision is required on whether to consider systems as independent entities, or to take a holistic SoS view.
Practical guidance: To be determined.
