System Procedure Managing Safety Change

The Safety Change Management requirement provides the context of the safety assurance activities as they relate to the Project Lifecycle defined in the RailCorp Project Management Methodology (RPMM). This procedure sets out the processes for managing safety risk within changes such that the changes are designed and implemented to reduce safety risk in operation to As Low As Reasonably Practicable (ALARP). The system safety lifecycle approach and activities are derived from the established international standard EN50126, which uses a systems engineering approach for managing safety, reliability, availability and maintainability throughout the project lifecycle. The Safety Change Management requirement reflects the safety lifecycle and systems engineering concepts from EN50126, and their application within the context of the RPMM.

Appendix A lists potential safety change management activities and identifies which are mandatory, recommended, or not required to support safety change management based on the outcome of the Safety Change Assessment and Reporting Determination (SCARD) impact assessment. The vast majority of change activities with safety impact are managed via a dedicated project and in accordance with the RailCorp Project Management Methodology (RPMM). Project Sponsors and Project Managers are responsible for RPMM activities and managing safety change management requirements throughout a project lifecycle (normally referred to as the safety lifecycle).
