The circular representation in Figure 2.1 conveys the principles of seamless management and  continuous improvement in service delivery over time. Application of the process is flexible and  may be tailored appropriately. The basis for analyzing and assessing a system differs for each organization. The level at  which SRM is conducted also varies by organization, change proponent, and the type of  change. SRM is carried out at the national level for major system acquisitions. It may also be  performed at the regional or local level to address proposed changes to equipment or Air Traffic  Control procedures.  Figure 2.2 augments Figure 2.1 by showing the safety deliverables required during the FAA  lifecycle management process. See  Section 2.4 for information about Technology Refreshment (TR) portfolio safety  requirements.  Table 2.1 summarizes the system safety deliverables that are part of the AMS / SRM  processes. Each deliverable is listed in the acquisition phase during which it must be  completed.  No one FAA organization has total approval authority. The PO is responsible for product  approval (i.e., deciding whether the developer has complied with the contract). The JRC has  funding approval (i.e., deciding whether to fund a project). The safety risk acceptor has  performance approval (i.e., deciding if the system’s performance is adequate (regardless of  whether the developer has complied with the contract)). Safety and Technical Training (AJI)  maintains the safety approval role (i.e., ensuring all system safety requirements are met). Each  approver has the authority to prevent the deployment of a system. This separation of approval  authority guarantees that checks and balances exist among lines of business that each have  2_SRMGSA_202003  Originally published March 2020  Uncontrolled copy when downloaded  6 2.2.1 System Safety Deliverables  2.2.2 Approval Authority Figure 2.2: FAA Lifecycle Management Process (with Safety Deliverables)
