How to use the SACE guidance

We have provided guidance on how to systematically integrate safety assurance into the development of an autonomous system (AS). A primary outcome of this integration is an explicit and structured safety case. More specifically, SACE offers a set of argument patterns, and the underlying assurance activities, that can be instantiated and specialised in order to develop the safety case for the AS.

This document is aimed at:

  • Safety engineers who are interested in understanding what must be done to provide the required assurance in the safety of an AS operating in a complex environment
  • System engineers and developers who are interested in understanding the safety assurance considerations when developing an AS
  • Reviewers and safety assessors who are interested in understanding what should be the focus of review and the criteria by which the sufficiency of the assurance activities should be judged.

When using this guidance it is recommended that the reader is aware of other sources of complementary guidance on best practice for the safety of autonomous systems such as UL4000 [24] or SCSC‐153B [36].

Throughout the guidance, the use of ”shall” indicates a required element of the guidance. Information marked as a “NOTE” or “EXAMPLE” is only used for clarification of the associated activities. A "NOTE” provides additional information, for clarification or advice purposes. An “EXAMPLE” is used to illustrate a particular point that is specific to a domain or technology. An example presented in the guidance is not meant to be exhaustive. Planned case studies and future experiments will provide fuller examples.
