Standards Development

Scope

This document offers a framework for system safety to facilitate the development of complex systems and defence programmes taking into account the specific needs of all stakeholders.

This document is applicable to:

a) complex systems in scope of defence programmes, including but not limited to protection systems, control systems, and information systems

b) systems whose behaviour could have an impact on the safety, and/or on the top level function of the system

c) a system-of-interest, whatever its location in a system hierarchy

d) those acquiring, specifying, developing, interacting with, using and assessing systems as well as by suppliers of systems and enabling systemsThis document addresses:

e) the achievement of an acceptable level of safety, addressing hazards arising from what the system does, or does not do

f) system safety within systems engineering processes as defined by ISO/IEC/IEE 15288:2023

g) the consideration of malevolent and unauthorised actions that are relevant to the objectives defined to achieve safety during all system life cycle stages

h) requirements for the realisation of safety relevant system elements and properties and for their assurance

This document does not directly address:

- systems engineering; those aspects are treated in ISO/IEC/IEEE 15288:2023

- requirements management; those aspects are treated in IEC 24748-2 [4]

- safety methods and techniques; for example per Functional Hazard Analysis, STPA, fault tree analysis, FME(C)A

- sub-systems/element realisation; however it includes provisions for:

o the realisation and acceptance of products compliant to recognised industry standards

o the acceptance of legacy systems
