AI-assisted draft. The three-dimension framework is credited to Lax and Sebenius. A book excerpt was read and used to check the saved summary; not every claim in that summary was adopted. The example and practical tool are new adaptations. This is not an account of a deal Shachar conducted or a promise of a negotiation outcome.

Three questions instead of another tactic

The authors distinguish three dimensions: tactics—the interaction between people; deal design—the substance and structure of an agreement; and setup—the parties, sequence, issues and alternatives surrounding it. Good communication still matters. The point is not to expect communication alone to repair an unsuitable arrangement.

For the application below, translate that distinction into three questions: are we misunderstanding one another? Is the proposed arrangement itself unsuitable? Or are we trying to decide with the wrong people, information or sequence of steps?

Example: a workshop everyone likes but nobody can approve

Imagine two groups planning a joint workshop. The organizers agree on the subject, but the discussion keeps returning to the date and number of participants. One group wants a large event; the other has little preparation time available. This is a fictional example.

At the conversation level, ask whether “large” means many registrations, a diverse audience or an opportunity to showcase work. At the proposal level, distinguish a small trial session from a wider event later. At the preparation level, establish who approves the venue, who commits to teaching, and who handles registration.

If the venue coordinator is absent from the process and nobody has checked availability, another hour of argument between the organizers will not produce a workable date. The barrier may not be resistance. A decision from somebody else may simply be missing.

SEE THE IDEA

Three places a conversation can get stuck.

An illustration from the fictional workshop. Each selection suggests a check, not a certain diagnosis of the barrier.

  1. ConversationWhat do we understand differently?
  2. ProposalDoes the arrangement fit?
  3. SetupWho or what is missing?

Conversation

Does “a large event” mean many registrations, a diverse audience or a chance to showcase work? First clarify what the words mean.

Proposal

Compare a small trial workshop with a wider event later. A different proposal might fit preparation resources better; that is an option, not a conclusion.

Setup

If venue availability is unchecked and teaching hours are unapproved, decisions from others are missing. Consult the venue coordinator and instructors before deciding registration scope.

Map roles rather than guessing motives

Make a simple map of the decision: who proposes, who knows, who approves, and who will do the work? One person can occupy several roles. Sometimes the person responsible for implementation is the one missing from the invitation.

Beside each role, write what needs clarification. Not “They are afraid of change,” but “We have not asked how much preparation time is needed.” Not “They are uncommitted,” but “The teaching hours have not been approved.” This keeps the map from becoming a collection of guesses about people.

For the workshop, the next step might be a short availability check with the venue coordinator, followed by a scope discussion with the instructors. Not everyone needs to attend every conversation. People whose participation the decision depends on do need a meaningful opportunity to shape it before it is presented as settled.

A four-line barrier check

The following is a new practical adaptation, not a table reproduced from the book. Choose one recurring conversation and complete four lines:

Decision: what must be settled for work to proceed?
Observed barrier: what actually happened—not what we think someone feels?
Missing element: information, a different option, an authorized person or suitable timing?
Next action: what can we check before scheduling the same meeting again?

For example: “We need to choose the workshop’s scope. In both discussions, we did not know how many instructors were available. We need an estimate of teaching hours. We will ask the instructors for two feasible scope options before deciding how many registrations to accept.” This tests a hypothesis about the obstacle instead of asking people to persuade harder.

Preparation is not a license for manipulation

Changing the sequence of conversations does not justify withholding information, inventing urgency or bypassing someone affected by the decision. Those are the editorial boundaries of the application proposed here. State what has already been decided and what remains open, and do not present interest in principle as a commitment.

Good preparation cannot eliminate a genuine resource shortage or disagreement. Sometimes the check reveals that the workshop is not feasible now. That is useful information. The practical value of the framework is choosing an action that fits the barrier: a better conversation for a misunderstanding, a different proposal for an unsuitable arrangement, or different preparation when the decision is not ready.
