Henden, a professor at the University of Hawaii in the United States, has summed up some effective negotiation skills. The 14 most commonly used ones are:
1. Be infectious: show your confidence and determination through your manners. This can increase your credibility and give your opponent a reason to accept your suggestion.
2. High starting point: higher than the initial request, leaving room for maneuver. After the concession, your position must be much better than the low starting point.
3. Don't waver: After you have determined a position, you must make it clear that you will not make concessions.
4. Limited power: To participate in negotiations in good faith, when a rule must be finalized, you can say that you still need the approval of your boss.
5. Each break: If you are negotiating with a group of opponents, try to convince one of the opponents to accept your suggestion. This person will help you convince others.
6. Interrupt negotiations or win time: Stop the negotiations within a certain period of time. Come back to renegotiate when the situation improves. During this time, you can go out and think about it, or you can leave the city very long.
7. Faceless, calmly coping: Don't answer your opponent with emotional words. Don't respond to the pressure of the other person, sit there and listen, don't have any expression on your face.
8. Patience: If time is in your hands, you can extend the negotiation time and increase your chances of winning. The less time your opponent has, the greater the pressure to accept your conditions.
9. Reducing differences: It is recommended to find a compromise between the two positions. In general, those who made this proposal earlier have less loss in the concession process.
10. When you are a veteran barrister: When you refute the other party’s proposal, you might as well say: “Before we accept or reject this proposal, let’s see what negative effects can be achieved if the other party’s proposal is adopted.†Let the other party realize that their proposal cannot withstand scrutiny without directly negating the opponent's suggestion.
11. First temptation: Before making a decision, you can indirectly convey your intentions to your opponent through a person or a reliable channel to test your opponent's reaction.
12. Unexpectedly: to disrupt the psychological balance of the opponent by unexpectedly changing the way of negotiation. Never let your opponent guess your next strategy.
13. Find a partner with a high prestige: Try to get the support of a prestigious person who is both respected by the negotiating opponent and supports your position.
14. Bargaining: If you are negotiating with several competitors at the same time, let them know about it. Arrange the negotiations with these competitors at a similar time and have them wait for a while before the meeting so that they can realize that someone is competing with themselves.
