To encourage a party with whom you are negotiating to accept your proposal, the least effective approach is to

a. consider the difficulties she may face in persuading others she must answer to or who may be responsible for implementing the agreement and find ways to help her make the proposal attractive to them.

b. agree to concede issues that are less important to you but that are of vital importance to her.

c. “dovetail” common interests, showing how your and her interests can be reconciled.

d. make clear to her the actions you will be forced to take if she does not agree to the proposal.
