RADPAC

A negotiation without preparation or a shared process can drift into vague discussion or harden into confrontation. RADPAC is a simple mnemonic for moving from relationship and diagnosis to proposals, commitment and a constructive close.

When to use it

• Use RADPAC to prepare and guide a relatively formal negotiation, especially when participants need a memorable common sequence.
• Adapt the pace and emphasis to the stakes, relationship, culture, authority and complexity of the issue.

Origins

RADPAC’s original author and date are not reliably established in the commonly circulated material. The framework appears in negotiation and communication training, often in very similar wording, but it should be treated as a practical mnemonic rather than a research-validated theory with a confirmed provenance.

What it is

• Rapport/relationship building
• Analysis
• Debate
• Proposal
• Agreement
• Close

The stages create a progression, not a rigid script. Negotiators may need to return to analysis after a proposal reveals a new constraint, or pause before agreement to verify authority and implementation detail.

How to use it

Work through each element deliberately.

Rapport/relationship building. Establish a professional tone and enough trust for candid exchange. The appropriate amount of social conversation varies across people and cultures, so avoid assuming that one style signals respect or seriousness. Use the stage to understand participants, roles and expectations.

Analysis. Clarify interests, facts, constraints, priorities, alternatives and decision authority. Test assumptions with open questions, reflect what you have heard and separate stated positions from the needs underneath them. If the parties agreed already, negotiation would be unnecessary; analysis locates the real differences and possible common ground.

Debate. Explore those differences without turning the exchange into a contest of assertions. Compare options against shared criteria, summarise frequently and identify trade-offs. Productive debate improves mutual understanding and generates possibilities that neither side brought to the table.

Proposal. Put viable options into clear conditional language. A proposal may cover the whole issue or one component. Listen for the value inside an imperfect counterproposal and develop it where possible. State assumptions, dependencies and what each party would give and receive.

Agreement. Restate every commitment, condition, owner, deadline and unresolved point. Confirm that participants have authority to commit, document the result in an appropriate form and ask each party to verify the same understanding. Include the process for changes, disputes and review.

Close. End with a concise confirmation of the outcome and immediate next steps. Acknowledge the work of the participants and protect the relationship needed for implementation or future negotiation.
