3-D Negotiation
David A. Lax & James K. Sebenius · 2006
"Most negotiation training only covers tactics at the table (the first dimension) — the bigger wins come from designing the deal's structure (the second dimension) and shaping the setup before anyone sits down (the third dimension)."
Two Harvard negotiation scholars argued that most books teach only one-third of the skill — what to say across the table — while ignoring the two dimensions that determine whether the table even produces a good outcome.
Tactics (1-D) are the conversational moves most books focus on: framing, concessions, persuasion in the room. Deal design (2-D) is architecture — sequencing agreements, structuring contingent contracts that let both sides bet on their own predictions, and finding a value-creating structure before value gets divided. Setup (3-D) happens away from the table entirely: who else needs to agree before this deal can close, what alternatives exist for each party, and what should happen before the first meeting so the table conversation is set up to succeed rather than doomed by a bad structure. Lax and Sebenius's core claim is that negotiators who lose usually didn't lose at the table — they lost in the setup, before the table conversation ever started.
What is the key difference between Lax and Sebenius's '3-D' (setup) and '1-D' (tactics) dimensions of negotiation?

"Deadlocks that look unsolvable through direct bargaining usually get broken by changing the game itself — the frame, the players at the table, or the process — rather than by pushing harder within the existing structure."
