I am agree with Ashraf mohammed as he said that Rank Ordering Approach  mainly focus on a methodology of negotiations, you are able to achieve better outcomes by ranking and leaving all the issues on the table and being transparent about it.

Thank you for your invitationagreed with answers dear colleagues.

Thanks for invitation,

In a very briefing words " Rank Ordering Approach" is mainly focusing on a methodology that during negotiations, you are able to achieve better outcomes by ranking and leaving all the issues on the table and being transparent about it.

By that methodology, both parties can compare their rank orderings and determine what are the full set of options that can be matching with their objectives, and consequently both parties are reaching a (win to win situation). 

I am not an expert so i would prefer to gain some knowledge from experts.

Thanks
