Abstract
Complicating relationships cause conflicts between stakeholders participating projects under the globalization. Conflicts are environmental factors of risks and leading to schedule problems and losses in the project when managers do not handle adequately. Commonly managers negotiate to resolve conflicts. Although ordinary non-zero-sum methodologies are efficient to make alternatives as cooperation and conciliation, it cannot be fully applicable to collaboration such as making renewed alternatives that can convince each other. In this paper, the authors propose a methodology of making renewed alternatives under understanding each value criteria of decision makers as negotiating for collaboration.
