Which of the following is NOT a negotiation tactic?

Team synergy is not typically classified as a negotiation tactic. Rather, it refers to the collaborative dynamic achieved when a group comes together to work effectively towards a common goal, leveraging the strengths of individual team members. While teamwork and collective efforts can influence negotiation outcomes, "team synergy" itself does not constitute a specific technique used to negotiate.

In contrast, commitment tactics involve establishing accountability or promises to secure agreement; inviting offers is a technique used to encourage the other party to propose their terms, fostering dialogue; and extreme demand in response can be seen as a strategy to create leverage by starting negotiations at a high or extreme position and then gradually conceding to a more acceptable level. Each of these is directly aimed at influencing the negotiation process and outcome, distinguishing them from the broader concept of team synergy.
