Chapter one ended with a doctor. A doctor does not open the consultation by passionately describing medicine. They ask questions, without shame, because they need the information to help you.
This chapter is the consultation itself. What to ask, in what order, and the two or three moves that separate discovery that wins deals from discovery that feels like a job interview neither of you wanted to be in.
why most discovery fails
Most sales discovery fails in one of two ways.
The first is shame. The salesperson feels awkward asking direct questions about money, competitors and decision making, so they skip them and pitch into the dark. Here is the thing a doctor understands that most salespeople never do: there is no shame in asking, because you need the information to properly help and diagnose the person in front of you. When you believe that, the questions stop feeling intrusive and start feeling like the most professional thing in the room.
The second is interrogation. The salesperson works through a list of discovery questions top to bottom, and the prospect feels like they are being processed. This was my personal fault when I started as an AE. I was robotic, going from question to question, and I was not even really listening. I was just thinking about the next question to ask. Information without connection. You might fill in the form, but nobody buys from a form.
The fix for both is the same: discovery is not a questionnaire. It is a conversation with a structure hidden inside it.
rapport is not a warm-up. it is the foundation
Before a single discovery question, you need the person to want to talk to you.
This does not need to be clever. It needs to be human. The weather. The tradespeople making noise in the background of their house. Ordinary UK small talk, deliberately a bit unpolished, because polish is exactly what makes people guarded. You are not performing charm. You are being a person, with a person.
What cannot be faked for long is genuine inquisitiveness. If you are actually interested in the human being on the other end of the call, they feel it, and they open up. If you are pretending, they feel that too. I will be honest, this did not come naturally to me. I am actually quite self absorbed, and in my early years I was only interested in speaking to buyers so that they would buy. I had to teach myself that, you know what, this person is interesting, and there are things I can learn from them regardless of whether they buy or not. Once that clicked, everything about my calls changed. People buy from people they feel something with. That is not a soft observation, it is the mechanism the whole call runs on.
On a typical first call, the opening fifteen minutes is rapport and discovery. It is also the part that decides everything that follows.
the flow of a discovery call
Here is the shape I teach, using an inbound enquiry as the example.
Open with the natural question: "How did you come across ourselves?" It is easy to answer, it gets them talking, and the answer is already discovery. Then the question that does more work than any other on the call:
"So what's the narrative here?"
Then stop. Let them go. A good prospect will launch into a long dialogue, and your whole job is active listening. The hmms and the yeps are not filler, they are what keeps the narrative flowing. People tell you remarkable things when you make it clear you are actually listening and in no rush to interrupt them with a pitch.
The narrative is the single most valuable thing discovery produces, because it is the problem in their words. You will pitch back in those words later, and it will land like you read their mind. You did not read their mind. You asked, and then you genuinely listened.
Some of the best discovery questions are simply invitations to give an opinion. One of the best I ever asked was as an SDR at NCC Group, ringing people about a phishing simulation tool. I asked an IT Security Manager: "What is your view on people's attitudes towards information security?" It worked because it hit his personal pain point. People were not taking it seriously, and at last somebody was asking him about it. One question, and he was telling me the real story.
ask the diagnosis as multiple choice
Here is the part of my approach that surprises people most.
Open questions are for the narrative. For the diagnosis, I use multiple choice.
Ask a buyer "so what's driving this project?" as an open question and watch what happens. The ones who know the answer tell you. The ones who do not get frustrated with the question, because you have just asked them to do analysis they have not done. And deep down they know they should have done it, which is exactly where the frustration comes from. So do not make them. Offer the options: is this driven by a customer requirement, a compliance framework, or are you forcing change internally? They just pick. It feels like help, not interrogation.
Same with competition. Ask it directly, and say the quiet part out loud: "Is this competitive? If so, we want to win, obviously. Tell me your criteria for choosing a vendor." Then give the criteria as choices too: price, speed, quality, output. Have them rank what matters.
The reason this works is the same clarity principle that runs through the whole methodology: buyers often do not know their own answer in the abstract, and open-ended questions create anxiety while choices create relief. And every option you offer is pre-mapped. You already know how you will pitch, forecast and close against each answer. The buyer experiences a helpful conversation. You are building a diagnosis.
Then timescales, and here is where most salespeople ask the wrong question. Do not ask when they want to sign. You need to understand the latest date in the cycle: when does the service need to be live? Say they are buying to fulfil a requirement in an audit. When does the audit have to be submitted? Work backwards from there. When does the service need to be live to make that date? How long does the service take to go live? How long will it take to get the contract signed? How long to get it approved internally? Now you have a real timeline, built from their deadline rather than their politeness.
never take an answer at face value
This is the master skill, and it is the one that separates professional discovery from polite discovery.
When a prospect gives you a surface answer, you have to be brave enough to challenge it. Not rudely, and never as a gotcha. The way to make a challenge safe is to justify it. Tell them you need to probe a bit more here, so that both of you get what you want out of the conversation. Framed like that, digging deeper lands as collaboration, not interrogation. You are not doubting them. You are serving the shared outcome, exactly like the doctor who asks the follow-up question you did not expect, because the obvious answer is not always the real one. The first answer is what the prospect thinks is true. The second answer, the one behind your follow-up, is usually what is actually true. Deals are won and lost in that gap.
the doctor's chart
Discovery has done its job when you can fill in the chart. Here is the minimum:
The narrative, in their words. The driver, graded against your options. Whether it is competitive, and if so their ranked criteria. Timescales. Any compelling events. That is what you need to pitch tailored, forecast honestly and control the close.
And then, a balance most salespeople get wrong: give and take. Discovery does not end after the first fifteen minutes. It is continuous through the whole relationship. But do not let the questions drag either, because they enquired to hear about your service and your price, and a discovery call that never gets there is its own kind of failure. Once you have the initial questions and the narrative, start pitching against their requirements, and keep discovering as you go.
While you pitch, keep it a dialogue. "Does that make sense?" every five or ten minutes does the job. It sounds small, but it is the difference between a conversation and a monologue, and monologues do not close.
Only once they are properly hooked do you get to the price, and after that the mechanics: the approval process, the paperwork, the economic buyer. Those matter enormously, and they have their own chapters coming. But they come after the diagnosis, never instead of it.
what this means for your team
If you are a founder, you probably do most of this by instinct. You are genuinely curious, you have no shame about asking, and you challenge weak answers because you actually need the truth. Your hires do not start with any of that, which is why their discovery calls produce forms instead of diagnoses.
The good news is that this structure is teachable. The opening questions, the narrative, the multiple choice diagnosis, the challenge line, the chart. A new salesperson can run it in their first month, and every call where the diagnosis proves right builds the confidence to ask braver questions on the next one.
