The negotiation process usually begins with a meeting to introduce the teams, define the ground rules and exchange proposals. At the second meeting, the proposals will be divided into three categories: monetary, non-monetary and budgetary management. Monetary elements deal with anything that has incremental or new costs, non-monetary elements try to provide a new or improved language to handle the agreement, and Housekeeping corrects spelling and grammar mistakes. As negotiations continue, the parties are discussing the underlying interests of their proposals and trying to find win-win solutions. Proposals on which the teams are unable to agree are withdrawn or submitted. A number of deposited points can be exchanged or on the eve of the end of negotiations in order to facilitate a negotiated agreement.
