mishap risk exists in the system being acquired. For significant mishap
risks, the program manager is required to elevate reporting of residual
mishap risk to higher levels of appropriate authority (such as the Program
Executive Officer or Component Acquisition Executive) for action or
acceptance. The program manager is encouraged to apply additional resources
or other remedies to help the developer satisfactorily resolve hazards
providing significant mishap risk. Table A-IV

manager and using organization should jointly determine the updated residual
mishap risk prior to acceptance of the risk and system hazards by the risk
acceptance authority, and should document the agreement between the user and
