To develop safety assessments with these broader scopes, the ANG NextGen Investment  Portfolio Leads must:  ANG has developed three SRM tools:  The Office of Aviation Safety includes the Air Traffic Safety Oversight Service (AOV), which  oversees the SRM process for system-oriented safety standards related to the acquisition and  implementation of new systems (including modernization/upgrades of legacy NAS systems) in  accordance with the current versions of FAA Order 1100.161,  Air Traffic Safety Oversight , and  AOV Safety Oversight Circular (SOC) 09-11,  Safety Oversight Standards. 4 It is important to  note that AOV must approve any mitigations identified in an SRM document that lower the  safety risk of hazards initially identified as high risk before those mitigations may be  implemented and the system(s) fielded.  4. AOV SOC 09-11 provides systems-oriented information and guidance material that may be used by the ATO to develop and implement procedures to comply with FAA Order 1100.161. 5. Excerpted from the Safety Collaboration Team Charter signed June 5, 2018. 6. The FAA SMS Committee is a cross-organizational coordinating body that focuses on safety and safety management. The purpose of the FAA SMS Committee is to assist SMS implementation, planning, and improvement by recommending policy and process guidance across the FAA. All such guidance must be approved by the FAA SMS Executive Council. The FAA SMS Committee also coordinates cross-organizational safety issues and safety management concerns in the FAA. 4_SRMGSA_202003  Originally published March 2020  Uncontrolled copy when downloaded  26 4.4  Safety Collaboration Team 5 4.3  Office of Aviation Safety • Ensure that capabilities under consideration are analyzed early (i.e., prior to the IARD) for possible safety ramifications due to integration with other NAS components; • Identify how the magnitude of the safety issues/concerns identified early in capability development may impact the way the capability is considered for further investment and development; • Support the transition of the capability to an implementing organization within the ATO, resulting in an SMS-compliant Operational Safety Assessment (OSA) prior to the IARD; and • Gather data on, understand, and articulate the safety issues/concerns as a capability evolves and moves through the acquisition lifecycle. • An  Integrated System Safety Assessment (ISSA)  assesses changes in safety risk resulting from the implementation of NextGen OIs. The ISSA Report serves as a foundational safety document that will feed into other safety analysis activities through the course of the program lifecycle process. • A  Service-Level Safety Assessment  is a means to assess current safety risk and provide a baseline for subsequent changes to the NAS. • The  Hazard Enterprise Architecture Traceability (HEAT)  tool provides an interactive platform that allows users to search for available safety data via the FAA EA element connected to the subject of their safety analyses/assessments. The HEAT tool is located in the  NAS Systems Engineering Portal. The FAA Safety Collaboration Team (SCT) was appointed by the FAA SMS Committee 6  to  serve as the technical advisory body to the committee and to facilitate the safety risk
