## 5.3 ASOR Development Process 

In the ASOR, safety requirements are developed to achieve the safety objectives identified in the OHA. Safety objectives and safety requirements must then be allocated (1) to the CNS/ATM system elements that provide the functional capability to perform the service and (2) to the stakeholders in control of or responsible for each of the elements. Safety objectives and requirements must be further synthesized into the appropriate standards and specifications, which are used by the FAA/ATO to ensure that systems are compliant. 

The ASOR uses the safety objectives and requirements developed and derived from the OHA to develop a strategy that takes into account procedural and architectural mitigations. The set of safety requirements to meet the objectives are allocated to the various ground and/or airborne CNS/ATM systems.
