SPIN Selling and MEDDIC answer two different questions. SPIN tells a rep how to run a sales conversation through four types of questions; MEDDIC tells the team whether a deal is qualified, using six elements a rep needs evidence on.
So the useful comparison is about fit: what each one covers, where they overlap and how a team runs both on the same deal. That is the point of this piece, which sits inside our sales methodology guide with the rest of the method family.
SPIN Selling, defined
SPIN Selling is a questioning method from Neil Rackham's 1988 book of the same name. Its four question types are Situation, Problem, Implication and Need-payoff, used roughly in that order to move a buyer from describing their situation to stating the value of solving their problem.
- 01SituationWhat only the buyer knows
- 02ProblemWhere does the process break?
- 03ImplicationWhat happens downstream when it does?
- 04Need-payoffWhat would cutting that in half be worth?
The method's owner, Huthwaite International, describes it as "born from observing 35,000+ real sales calls". The most common mistake is rushing from Problem questions to the solution without the Implication questions that build urgency. Implication questions carry the method. A buyer who has described a problem but never its consequences has no reason to act this quarter.
MEDDIC, defined
MEDDIC is a qualification framework with six elements: Metrics, Economic Buyer, Decision Criteria, Decision Process, Identify Pain and Champion. A deal is qualified when the rep has buyer-confirmed evidence on all six. The letters say what to find out. They say nothing about how to ask for it, which is where a questioning method such as SPIN comes in, and why the two so often turn up in the same sales team.
It began at PTC, the software company, in the 1990s, as a structured approach to qualification. MEDDPICC adds Paper Process and Competition, and our MEDDPICC vs MEDDIC piece covers that choice. The six letters are on our MEDDIC page.
Side by side
| Dimension | SPIN Selling | MEDDIC |
|---|---|---|
| What it is | A method for running the conversation | A framework for qualifying the deal |
| Question it answers | What do I ask next on this call? | Is this deal real, and what is missing? |
| Unit | One conversation | The whole deal, across many conversations |
| Who uses it most | The rep, during the call | The rep and manager, in the deal review and forecast |
| Output | The buyer states the problem, its consequences and the value of fixing it | Evidence on six elements, and a list of gaps |
| How it breaks | Implication questions skipped; questions read from a list | Letters filled with the rep's guesses; treated as CRM fields |
| Origin | Neil Rackham, 1988, research on sales calls | PTC, 1990s, internal qualification practice |
They do different jobs. A team can run SPIN without MEDDIC and qualify nothing, or run MEDDIC without a questioning method and leave reps unsure how to get the evidence each letter asks for.
Which SPIN questions fill which MEDDIC letters
Each SPIN question type tends to produce the evidence for one or two MEDDIC letters.
| MEDDIC element | SPIN question type that fills it | Example question |
|---|---|---|
| Metrics | Implication, then Need-payoff | "What does each delay cost you?" then "What would cutting that in half be worth?" |
| Economic Buyer | Situation, then Implication | "Who signs off on spend like this?" then "How does this problem show up on their numbers?" |
| Decision Criteria | Need-payoff | "If you solved this, how would you judge whether it worked?" |
| Decision Process | Situation | "Walk me through how a purchase like this gets approved here." |
| Identify Pain | Problem, then Implication | "Where does the process break?" then "What happens downstream when it does?" |
| Champion | Need-payoff | "Who else would benefit if this were fixed, and would you take it to them?" |
Two patterns stand out. Metrics and Identify Pain depend on Implication questions, which are the ones reps skip. And Decision Process and Economic Buyer often come from plain Situation questions, which reps ask too early, before the buyer has a reason to share how money gets approved.
One deal, run through both
This example is illustrative. Arrowmere is a fictional 600-person logistics firm; Dana is VP of Operations.
On the call (SPIN). Situation: "How do your planners handle a load that has to be re-dispatched?" Dana: "By hand, from a spreadsheet." Problem: "How often does that go wrong?" Dana: "Thirty times a month, maybe more." Implication: "What does each one cost, and what else does it knock on?" Dana: "About $1,800 in rework and overtime, and it usually makes two other loads late." Need-payoff: "If you halved those, what would that mean for peak season?" Dana: "I wouldn't need to hire two more planners."
In the review (MEDDIC).
| Element | Evidence | Status |
|---|---|---|
| Metrics | $1,800 per re-dispatch, thirty a month, two planner hires avoided | Yes |
| Economic Buyer | Not discussed | Gap |
| Decision Criteria | Not discussed | Gap |
| Decision Process | Not discussed | Gap |
| Identify Pain | Re-dispatches from a manual spreadsheet, knock-on late loads | Yes |
| Champion | Dana is motivated; she has not done anything for the deal yet | Unproven |
The SPIN call was strong and produced two letters. The review shows the deal is missing who signs and how. The next call needs Situation questions about approval and a Need-payoff question that asks Dana to act: "Would you bring your CFO into the next conversation so they hear the $1,800 figure from you?"
Which fits which sales motion
The length of the sale and the number of people in it decide how much of each a team needs.
Short, single-buyer sales. One person decides, often on the first or second call. SPIN does most of the work here, because the rep has to get that person to state the problem and its cost quickly. A full MEDDIC review on every deal is more process than the deal can carry. A light check on Metrics and the decision process is usually enough.
Mid-market deals with a small buying group. The champion and one approver make the call over a few weeks. Both methods earn their place. SPIN runs the discovery calls, and a MEDDIC review after each one shows whether the approver has heard the case.
Enterprise deals with many stakeholders. Several people with different reasons, a procurement step and often a competitor. MEDDIC, or MEDDPICC with Paper Process and Competition added, carries the deal. SPIN still runs each conversation, and each new stakeholder needs their own Implication questions: the CFO's consequences are different from Dana's.
What SPIN leaves out in any motion. A Need-payoff question can surface a likely champion, but SPIN has no step for testing whether that person will act, and nothing on the paper process or the competition. Those come from the qualification side. A team that runs SPIN alone in a complex sale will have strong first calls and still be surprised at the end of the quarter.
Where teams go wrong
Choosing one and calling it a methodology. SPIN alone leaves no qualification standard. MEDDIC alone leaves reps with a list of fields and no way to ask for them.
Filling MEDDIC from memory. A letter marked green because the rep "feels good" about the champion is a forecast. Each letter needs something the buyer said or did.
Spending the call on Situation questions. Questions the rep could have answered from the website or the CRM use up the buyer's patience before the Problem and Implication questions arrive. Do the research before the call and keep Situation questions for what only the buyer knows, such as how approval works.
Running SPIN as a script. A prepared list stops working the moment the buyer takes the conversation somewhere else. The question types are a sequence to follow, and the wording is the rep's.
Choosing, and coaching both on live deals
If your reps struggle to get buyers to state the cost of a problem, SPIN's Implication questions are the fix. If your forecast keeps slipping on deals that looked good, MEDDIC is the fix. Many B2B teams need both, and a rollout that teaches them at a kickoff and never coaches them on a deal fades fast, as our post on methodology adoption at day 91 explains. The steps are in how to roll out a sales methodology.
Our AI sales experts coach the team's own method on the live pipeline. The rep talks a deal through with Caty on a call; Caty reads it against MEDDIC or MEDDPICC, names the missing elements and plans the questions for the next call. A rep who cannot talk can type it in. How to coach MEDDPICC on live deals shows the approach. If your reps ask good Implication questions and your forecast still slips, or the other way round, talk to us.
FAQ
What is the difference between SPIN Selling and MEDDIC?
SPIN Selling is a method for running a sales conversation through Situation, Problem, Implication and Need-payoff questions. MEDDIC is a framework for qualifying a deal on six elements: Metrics, Economic Buyer, Decision Criteria, Decision Process, Identify Pain and Champion. SPIN guides the call; MEDDIC checks the deal.
Can you use SPIN Selling and MEDDIC together?
SPIN Selling and MEDDIC work well together, and teams that use either usually benefit from the other. SPIN's questions produce the evidence MEDDIC asks for: Implication questions fill Metrics and Identify Pain, Situation questions fill Decision Process, and Need-payoff questions test the Champion. Review the deal against MEDDIC after each SPIN-led call.
Is SPIN Selling still relevant?
SPIN Selling is still relevant, because its four question types still describe how good discovery moves from facts to consequences to value. The part most reps skip, Implication questions, is the part that turns a described problem into one the buyer wants solved this quarter, and that gap shows up on calls today.
Should I choose SPIN or MEDDPICC?
Choose based on the problem you have. If reps cannot get buyers to state the cost of a problem, start with SPIN. If deals slip late because nobody knew who signs or how, start with MEDDPICC. Many B2B teams end up running both, one on the call and one in the review.
