System Safety Assurance (SSA) provides the necessary governance, processes and objective evidence by which all interested parties satisfy themselves that a given product, service, system or organisational change can be safely integrated, operated and maintained into the transport network, so far as is reasonably practicable (SFAIRP).

This guideline aims to create a harmonised, uniform and consistent approach for managing the safety of existing and future Australian railway network assets and systems.

The purpose of this guideline is to assist rail organisations in the establishment and running of assurance activities within their business. The assurance activities will be scalable and tailorable to meet the complexities of a proposed change of product, service, system or organisational change.
