摘要:This scientific study is investigating the economic and success factors of success in negotiation in the world of trade and sale. In addition to the keynotes of the Harvard concept, my study focuses largely on trust and transparency at annual meetings or other meetings held throughout the year, strongly favouring a satisfactory result for both negotiating parties. A conceptual model has been proposed to merge the fundamental principles of the Harvard Negotiation Concept with the finding that trust and transparency in communication is a key factor in terms of economic success experiences and socio - mental satisfaction.
