## 6 Other Considerations 

## 6.1 Baseline Change Management 

For any acquisition program under its jurisdiction, the Joint Resources Council (JRC) approves and baselines all Federal Aviation Administration (FAA) program documents required by the FAA Acquisition Management System (AMS) (i.e., Program Requirements Documents (PRDs), acquisition program baselines, Business Cases, and Implementation Strategy and Planning Documents). The JRC may also make acquisition program baseline change decisions that alter program performance or cost and schedule baselines during the Solution Implementation phase for investment programs. From a Safety Risk Management (SRM) viewpoint, if a baseline change is being proposed, the Program Office (PO) may need to review and update the Program Safety Plan (PSP) and any safety analyses/assessments that have already been completed to ensure that the new baseline does not impact the risk mitigation strategies already identified. If the proposed change does impact risk mitigation strategies, then the predicted residual risk identified in the completed safety analyses/assessments may not be achievable, and the new predicted residual risk without these mitigations implemented may be unacceptable. 

A baseline change could affect already identified risk mitigation strategies in the following ways: 

• If the program cost is being re-baselined, the proposed new budget may not include funding to implement the mitigations previously identified. 

• If the schedule is being re-baselined, the proposed new schedule may impact the temporal aspects of the identified risk mitigation strategy. In other words, the planned mitigations may not be in place as expected and required. 

• If the performance is being re-baselined, the new requirements may be sufficiently different from the assumptions made. Analyses conducted as part of previous safety assessments may no longer apply, invalidating previously identified risk mitigation strategies. 

## 6.2 Program Safety Requirements for Decommissioning and Disposal 

Disposal of an asset or program is part of the In-Service Management phase of the AMS process and, as such, requires SRM as part of its lifecycle management 1 . In addition, decommissioning a service provided by a program asset targeted for disposal could occur much earlier than the actual disposal and must also meet all SRM requirements. Programs or assets facing disposal often have their SRM requirements met by the program or asset replacing them, but this is not always the case. 2 Prior to the decommissioning and/or disposal of an asset or program, the associated PO should contact the Safety and Technical Training (AJI) Safety Case Lead (SCL) to convene a Safety Strategy Meeting (SSM) to determine whether SRM analysis and subsequent SRM documents are required. If so, an SRM panel will perform an analysis, similar to a Preliminary Hazard Analysis (PHA), to identify safety hazards associated with the disposal activity. This may include deactivation, deactivation and replacement of the system, or similar considerations.
