I am very stuck with this assignment, and I don't have an idea on how to begin.

Please use the template in Appendix B in the Ertel and Fisher book to prepare for an upcoming negotiation with an external party, a person inside your organization (boss or co-worker), or a family member. After you have filled in the template, please provide a robust summary of what you learned, how you felt more prepared, how did decision-making theory inform your preparation, and what else you feel like you might need to know that the tool did not help you to analyze.
