The primary focus of ASET IV&V is on two Shuttle problem reporting and change instruments -- Space Shuttle Orbiter Avionics Software Discrepancy Reports (DRs)

... LEVELS OF IV&V ANALYSIS The ASET IV&V process entails three levels of analysis that correspond to the scope parameters described earlier in this chapter -- limited, focused, and comprehensive. These are cumulative in the order presented, that is, focused goes beyond limited, and comprehensive goes beyond focused.

... Such DRs may eventually require a Focused or Comprehensive analysis on a later 01 when a software change is implement. A key portion of this first stage of analysis is risk assessment, as it both aids the SASCB in its approval decision and serves as a basis for determining what further analysis is required.
