In negotiation, MDO (Most Desirable Outcome), LDO (Least Desirable Outcome), and BATNA (Best Alternative to a Negotiated Agreement) are the three positions every negotiator must define before entering any significant commercial negotiation. Together they form the complete range of your negotiating position — your ideal outcome, your minimum acceptable outcome, and your alternative if no deal is reached. Without these three defined, you are not negotiating. You are reacting.
Why Most Negotiators Fail Before They Begin
In my 26 years of training sales and procurement teams across 14 countries, the single most common mistake I observe is this: professionals walk into negotiations knowing what they want but not knowing where they will stop. They have a price in mind, a target outcome they hope to achieve. But they have not defined their walk-away point. And they have not thought seriously about what happens if the negotiation fails entirely.
This is not a small gap. It is the gap that causes professionals to accept deals they should have walked away from. It is the gap that causes experienced negotiators to give away concessions under pressure that they did not need to give. It is what I call negotiating against yourself before you sit down.
MDO, LDO, and BATNA are the antidote.
MDO — Most Desirable Outcome
Your MDO is the best possible result you could achieve in this negotiation — the outcome if everything goes your way, the other side is accommodating, and you lose nothing from your ideal position.
It is important to understand that your MDO is not a fantasy. It should be ambitious, but it must be grounded in what is theoretically achievable given the circumstances. If you are negotiating a vendor contract, your MDO might be maximum payment terms, minimum price, all quality guarantees, and a first-refusal clause. All of these are possible. Not all will be achieved — but that is the point of negotiation.
The most common mistake at this stage is under-anchoring — opening at a number that feels "fair" or "reasonable" rather than at your true MDO. This is a critical error. The research on anchoring in negotiation is clear: the first number stated in a negotiation has a disproportionate influence on the final outcome, regardless of how the other side responds initially.
LDO — Least Desirable Outcome
Your LDO is the minimum you are willing to accept — the deal below which you will walk away. It is your walk-away point, your reservation price, your floor.
Knowing your LDO before you enter a negotiation does three things:
- It prevents you from accepting deals that do not serve your interests, even under emotional or time pressure
- It gives you a clear decision framework when the other party makes a final offer
- It stops you from giving concessions below your minimum when the other side pushes — because you know exactly where your floor is
Your LDO should be defined in advance, in writing, and reviewed before the negotiation — not calculated on the fly when you are under pressure and the other side is waiting for an answer.
BATNA — Best Alternative to a Negotiated Agreement
BATNA answers the question: what will I do if this negotiation produces no agreement?
BATNA was developed by Roger Fisher and William Ury of Harvard's Program on Negotiation and is arguably the single most powerful concept in negotiation theory. Its power lies in this principle: the strength of your BATNA determines the strength of your negotiating position.
If you have no alternative to the deal on the table — if this negotiation failing means you have no vendor, no client, no project — your BATNA is weak, and you will negotiate from fear. The other party will feel this, and will exploit it.
If you have three other buyers interested in your product, or two other vendors who can deliver what you need, your BATNA is strong — and you negotiate from confidence. You can hold your LDO firmly because you have an alternative that works.
How MDO, LDO, and BATNA Work Together in Practice
Let us take a concrete example. Imagine you are negotiating a vendor contract for a large construction project.
Your MDO: ₹80 per unit, 60-day payment terms, 2-year price lock, penalty clause for delays.
Your LDO: ₹92 per unit, 30-day payment terms, 1-year price lock, no penalty clause.
Your BATNA: Vendor B has quoted ₹94 per unit with 30-day terms.
Now you walk in with clarity. You open at ₹80. You know you can go to ₹92 if needed. And you know that if this negotiation fails, you have Vendor B at ₹94 — so going beyond ₹92 makes no sense.
This is not magic. It is preparation. And it is the difference between negotiators who consistently achieve excellent outcomes and those who consistently feel they left value on the table.
The Negotiation Planning Matrix
In the PowerFULL Negotiator programme, every participant completes a structured Negotiation Planning Matrix before practising any negotiation scenario. This matrix maps their MDO, LDO, BATNA, Give-Get variables, Game Changer variables, and their assessment of the other party's likely position — all on a single planning tool.
The matrix is available as a free download for readers of The PowerFULL Negotiator. If you have a copy of the book, visit mihirkoltharkar.com/pn-matrix to access your copy.
Common Mistakes in Applying MDO, LDO, and BATNA
- Setting your LDO too high in advance — pre-emptively conceding to yourself before the negotiation has even started
- Not improving your BATNA before high-stakes negotiations — getting quotes from alternative vendors, exploring other buyers, creating genuine alternatives rather than accepting your current alternatives as fixed
- Revealing your BATNA prematurely — telling the other side you have alternatives is a tactic; revealing the specifics is a vulnerability
- Adjusting your LDO during the negotiation under pressure — this is the most dangerous mistake. Your LDO is set before you walk in. It does not move because the other side pushed back emotionally

What is MDO in negotiation?
MDO stands for Most Desirable Outcome. It is the best possible result you could achieve in a negotiation — the outcome if everything goes your way. You should always open at or near your MDO, because the first number sets the anchor for everything that follows.
What is LDO in negotiation?
LDO stands for Least Desirable Outcome. It is the minimum acceptable result in a negotiation — the point below which you should walk away. Knowing your LDO before you enter a negotiation prevents you from being pressured into accepting a deal that does not serve your interests.
What is BATNA in negotiation?
BATNA stands for Best Alternative to a Negotiated Agreement. It is what you will do if the current negotiation fails to reach an agreement. A strong BATNA gives you negotiation power — when you have a good alternative, you negotiate from a position of confidence rather than desperation.
How do MDO, LDO and BATNA work together?
MDO, LDO, and BATNA form a complete negotiation position framework. Your MDO is where you open. Your LDO is your walk-away point. Your BATNA determines how firmly you can hold your LDO — a strong BATNA means a higher LDO; a weak BATNA means you may need to accept less. Together, these three positions define your entire negotiation range.
