Successful negotiations require the ability to determine by analysis the best way to convince and to establish influence strategies in order to obtain an agreement. The parties’ interests are balanced in the final agreement by finding a mutual advantage.

Knowing and practicing tricks and games in negotiation develop the negotiator's spontaneity and confidence in finding mutually advantageous solutions. This is the only guarantee that the post negotiation agreement will be implemented.

Group negotiation is fundamental in decision-making, as it is one of the main characteristics of the participative working style. Mutual interests found in creative solutions and motivating the group towards progress are some of the results of correct and continuous application of intra-negotiation techniques.

Inter-Negotiation becomes more difficult since overlapping expectations and objectives becomes stronger and the use of influence policy becomes critical. Groups interact through ideas, values, styles and standards of their members. Finding integrating solutions contributes to increased admiration, trust, respect and loyalty to the detriment of disagreements, jealousies and resentments.
