“negotiating tool”
I believe in burning the midnight oil to unilaterally craft a fully detailed draft document for a deal.
The document should be drawn to meet the legitimate needs of all parties involved to the extent possible.
Other parties might also draw up similar documents so all likely issues and proposed solutions are known.
Only then should negotiation take place.
I’ve been in a few business negotiations, not a lot, but we never had paper in front of us. Paper always came after the deal.
