dependencies, and holistic performance of the NAS to be allocated among integral groups of  dependent NAS systems. EA views, more so than roadmaps, help control the impacts of  change among NAS systems.  The PO is responsible for monitoring safety requirements of acquisition programs to ensure the  requirements are met through design audits, developmental and operational tests and  evaluations, and performance checks (most notably before the Initial Operating Capability and  the Post-Implementation Review). The PO must also identify programmatic risks (e.g., cost or  schedule) that could affect safety.  When forming a Program Safety Team (PST), the PO should choose people who are able to:  The PO must ensure that all members of the PST receive SMS training and understand the  SRM process.  For SRM efforts conducted as part of the AMS process, the PO should hold a meeting with the  ANG Enterprise Safety Team (EST) 8  to review any relevant enterprise safety assessments and  HEAT reports and to assist with SRM compliance. The PO must include the PST SRM efforts in  7. For information regarding the roles and responsibilities of POs not part of the ATO, contact the Safety Engineering Team, AJI-314. 8. The ANG EST develops processes and provides guidance that enforces SMS compliance for all of NextGen. The ANG EST is responsible for assessing the safety of highly complex and interrelated systems in the NAS and identifying potential safety hazards and safety benefits that may result from planned NAS changes associated with NextGen OIs. 9.

Many functions performed by successful acquisition POs are beyond the scope of the SMS and  the SRMGSA. However, some of these functions are relevant to fulfilling the SRM requirements  as they relate to acquiring new solutions. Among them are planning and resource  management, which includes ensuring that SRM considerations are part of the decision-making  process. The PO must ensure that SRM policy and guidelines are followed.  PO Roles and Responsibilities • Track and analyze safety compliance for the program,
