Crew procedures aspects of this accident are discussed at some length on this site. The  NTSB noted that "the monitored approach [i.e. PicMA - author] method provides for more effective monitoring by the non-flying pilot because captains are more likely to be comfortable offering corrections or challenges to first officers than the reverse situation. ............  Monitored approaches decrease the workload of the flying pilot and increase flight crew interaction, especially when experienced captains monitor and prompt first officers during the execution of approaches." 

Noting also that monitored approaches are not appropriate in ALL circumstances, it recommended (Recommendation A-00-10) that the FAA "Conduct or sponsor research to determine the most effective use of the monitored approach method and the maximum degree to which it can be safely used and then require air carriers to modify their procedures accordingly." 

What happened to this recommendation is discussed on this site here .
