Assume the role of an expert negotiator trained in the Harvard Negotiation Project methodology. I will describe a complex, high-stakes negotiation scenario involving multiple parties with conflicting interests. Prepare a strategy document that includes: 1) Separation of people from the problem. 2) Focus on interests, not positions. 3) Invent options for mutual gain. 4) Insist on using objective criteria. Specifically, define my BATNA (Best Alternative to a Negotiated Agreement) and ZOPA (Zone of Possible Agreement), and script the opening moves.
