It also improves the chances of reaching reaching an agreement. By presenting multiple offers, it shows you are flexible. disagree with this post or add on to the postarrow_forwardThe strategy of Multiple Equivalent Simultaneous Offers involves presenting several equally valuable options to the other party during negotiations. This approach benefits negotiators by creating flexibility and increasing the chances of finding a mutually agreeable solution. By offering multiple options, negotiators show that they are open to compromise, which can build trust and make the negotiation process smoother. It also helps avoid getting stuck on one issue, as the other party can choose from several alternatives that meet their needs. In my experience, using MESOs in a work negotiation helped both parties reach an agreement more quickly because each option was carefully thought out to address different needs, and this made it easier for us to settle on one that worked for both sides. This strategy can also reveal what is most important to the other party, helping negotiators understand their priorities better. agree or disagree with the postarrow_forwardExamine the conflicts between improving customer service levels and controlling costs in sales.
