SALES METHODOLOGIES
A sales methodology is a shared way of thinking that tells salespeople how to lead conversations and decisions with customers; a sales process only describes the stages a deal moves through. Choose one by the complexity of the decision, the number of people involved, and what fails in your team today.
EIGHT APPROACHES
Each methodology answers a different question. Some guide the conversation, some qualify the deal, some shape the salesperson's stance. None of them is right for every team.
Origin
Neil Rackham, based on research into large numbers of sales calls; book published in 1988.
Core idea
Four types of questions (Situation, Problem, Implication, Need-payoff) that help the buyer put the value of solving a problem into their own words.
Strong at
Discovery conversations in larger, complex sales.
Weaker, or fits less
It is a questioning model rather than a full process: it says less about qualification, buying groups or what happens after the decision.
Best fit
Teams that need better discovery questions.
Origin
David Sandler, late 1960s; taught through Sandler Training.
Core idea
Buyer and seller qualify each other as equals: up-front contracts, pain, budget and decision before any presentation, completed in order like the compartments of a submarine.
Strong at
Ending the chase and giving every meeting a clear outcome, including “no”.
Weaker, or fits less
Built mainly around one buyer; some techniques work only when they are sincere.
Best fit
Teams losing time on unqualified prospects and “let me think about it” endings.
Origin
A qualification framework developed at PTC in the 1990s.
Core idea
Check the deal against Metrics, Economic buyer, Decision criteria, Decision process, Identify pain and Champion; MEDDPICC adds Paper process and Competition.
Strong at
Inspecting and forecasting complex deals with many stakeholders.
Weaker, or fits less
It describes the deal more than how to lead the conversation with the customer.
Best fit
Complex B2B sales with long cycles and buying committees.
Origin
Matthew Dixon and Brent Adamson, 2011, based on CEB research.
Core idea
Teach the customer something new about their business, tailor the message to each stakeholder, and take control of the sale.
Strong at
Markets where buyers believe they already know what they need, and a new insight sets you apart.
Weaker, or fits less
It needs real insight to teach; if the insight comes before understanding the customer's situation, it can miss the actual problem.
Best fit
Experienced teams selling to well-informed buyers.
Origin
Winning by Design, for recurring-revenue businesses.
Core idea
Situation, Pain, Impact, Critical Event and Decision, used as one shared language by sales, onboarding and customer success.
Strong at
Carrying one diagnosis across teams and keeping the focus on customer impact.
Weaker, or fits less
It tends to take the stated pain at face value and is lighter on stakeholder mapping than MEDDIC.
Best fit
SaaS and subscription businesses.
Origin
Mack Hanan, in the 1970s.
Core idea
The salesperson acts as an adviser who understands the customer's business and recommends what improves it.
Strong at
Trust and long-term relationships.
Weaker, or fits less
It describes a stance more than a step-by-step process, so quality depends heavily on the individual.
Best fit
Services and complex products where expertise matters.
Origin
Mike Bosworth, in the 1980s.
Core idea
Find a pain the customer admits, then connect it to your solution with a shared picture of how it gets solved.
Strong at
Complex products with a clear business case.
Weaker, or fits less
It starts from your own solution set, so there is a risk of fitting the problem to the product.
Best fit
B2B technology and other complex products.
Origin
Miroslav Ćurčić, developed while running his own company and training his own salespeople; described in the book Diagnostic Sales.
Core idea
The Sales ARC™: Agreement, Root Cause, Choices and Soft Landing. The salesperson takes responsibility for the quality of the customer's decision, including saying “this is not for you”.
Strong at
Decisions with consequences, and passing the same way of working on to a team, to new hires and into software.
Weaker, or fits less
Not the right fit for simple transactions where the customer already knows exactly what they want and a wrong choice costs little, for offers that are knowingly not in the customer's best interest, or for organisations that punish an honest “no”.
Best fit
Wherever a wrong decision has consequences, in B2B and in B2C.
HOW TO CHOOSE
Start from your situation, not from the most popular name.
Many people, long cycles and high stakes call for both a conversation model and a way to qualify the deal. Simple, repeat purchases need far less.
Training that does not stick, hiring people who cannot diagnose, or know-how that leaves with people. Each points to a different first step.
SPIN, Sandler and the Sales ARC™ guide the conversation; MEDDIC and SPICED structure what you need to know about the deal.
The higher the cost, in money, time, health or safety, the more the diagnosis matters before any recommendation.
COMBINING
Yes, and many teams do. A qualification framework such as MEDDIC or MEDDPICC can inspect the deal, while a conversation model such as the Sales ARC™ or SPIN guides the conversation itself.
What matters is one shared language for the team, not the number of frameworks. Adding a step for the root cause before any recommendation improves most approaches, whichever one a team already uses.
FAQ
There is no single best one. The right choice depends on how complex the decision is, how many people take part in it, what a wrong decision costs the customer, and what fails in your team today.
Solution selling starts from a pain the customer admits and connects it to your solution. Consultative selling starts from the customer's business and goals, with the salesperson acting as an adviser. Solution selling is more structured around the offer; consultative selling is more a stance than a process.
SPIN is a questioning model for discovery. Diagnostic Sales uses the Sales ARC™: it starts with an explicit agreement about the conversation, looks for the root cause behind the first request, narrows the options to two or three real choices, including not buying, and ends with a soft landing that stabilises the decision.
For complex B2B sales with many stakeholders, teams often combine a qualification framework such as MEDDIC or MEDDPICC with a conversation model such as the Sales ARC™ or SPIN. For B2C decisions where a wrong choice costs money, time, health or safety, the diagnostic conversation matters more than deal qualification; the same arc works at a different depth.
A sales methodology is a shared way of thinking that tells salespeople how to lead conversations and decisions with customers; a sales process only describes the stages a deal moves through.

A free initial conversation about where your team is now: training, hiring or knowledge. Miroslav suggests the next steps; sometimes the honest answer is that you need nothing from us.
