## 2.3 Program Safety Requirements 

## 2.3.1 Achieving a CRDR Decision 

Research and system analyses are often required during service analysis and strategic planning to mature operational concepts, reduce risk, and/or define requirements before a decision to proceed in the lifecycle management process is made. Service analysis and strategic planning policies apply when deciding whether to add a service shortfall or new operational concept to the NAS Concept of Operations (ConOps) and FAA EA. 

The CRDR Decision occurs at the end of the Service Analysis and Strategic Planning phase of the AMS when an EA roadmap indicates action must be taken to address a critical mission shortfall. (Shortfalls often stem from National Transportation Safety Board recommendations or from emergent in-service operational issues due to the evolving operational environment, rather than from any latent defects of legacy NAS systems.) The CRDR Decision can also be based on some exceptional opportunities that could substantially benefit the FAA. In either case, the decision is based on speculative activities such as simulation, Functional Analysis (FA), and computer-human interface development to define potential requirements; develop operational concepts; and avoid, transfer, or reduce safety risk before entering the IA phase. 

The Safety Collaboration Team (SCT) was appointed by the FAA SMS Committee to facilitate the integrated safety management of pre-decisional NAS changes affecting the FAA. In doing so, the committee recognized the need to ensure that safety is not compromised when the FAA proposes pre-decisional changes that affect NAS operations. SCT activities are outside the scope of the SRMGSA. 

## 2.3.2 Achieving an IARD 

The IARD occurs at the end of the CRD phase. At the IARD, the JRC determines whether the ConOps, preliminary requirements, EA products and amendments, and preliminary program investment alternatives are sufficiently defined to warrant entry into the IA phase. The decision is made within the context of all ongoing and planned investment activities to sustain and improve service delivery. It ensures proposals are consistent with overall corporate needs and planning. CRD phase activities occur prior to the establishment of clear functions, baseline requirements, alternative solutions, and solution design. 

If the concept under development requires that the proposed system, procedural change, demonstration hardware, or modified software “go live” (in a parallel, online, but nonoperational manner), SRM must be conducted. This is especially true if the system’s going live involves the collection of feedback from Air Traffic personnel, suitability demonstrations, field testing, flight tests, or operational prototypes that must be exposed to field conditions only found at operational NAS facilities.

## 2.3.2.1.1 EA Safety Roadmap 

The EA Safety Roadmap applies to the NAS as a whole and provides a broader context for Next Generation Air Transportation System changes, proactively aiming to manage safety risk in the NAS. 

## 2.3.2.1.2 PSP 

The PSP is the PO’s plan for the program’s safety process. The PSP is used to ensure compliance with provisions of the ATO SMS Manual and the SRMGSA. The PO must adjust
