At this point, you have hammered out all agreements, or have you? And, you are ready to close the deal. This is yet another opportunity to introduce sensitive issues or any others issues you desire but have not yet formed an agreement. This must be a small number of issues and your opponent should be interested in finalizing the deal that you both have worked diligently to form.
This works best when other conditions line up to assist. You can set the stage to create those conditions, such as at the end of the day maybe on a Friday when everyone is looking forward to a weekend, something good just occurred for your opponent, you are negotiating with the decision maker, etc. Bring up those issues now as in, “here is what we need and let's just ink this deal so we can go have a beer” (insert drink or event of choice here). Used wisely and carefully, you've made it happen!
