Coaching Gap Selling means taking one behavior the method asks for, such as getting the buyer to quantify impact, and working on it with one rep on their live deals until they do it without being reminded. A frontline manager does it weekly, in sessions of 20 to 30 minutes, and checks it again a few weeks later on a real call.
This piece covers the coaching job in Gap Selling's terms. For how Gap Selling compares with other methods, read the sales methodology guide; for the session format across methods, the sales coaching framework; for the term, What is Gap Selling?.
What Gap Selling is
Gap Selling is a problem-centric sales methodology: the rep sells the distance between where the buyer is and where the buyer needs to be, and the product comes in only once that distance is clear. Discovery maps the current state, the root cause of the problem, its impact on the business and the future state the buyer wants. The gap between the two states is what the buyer pays to close.
For a coach, that changes what to listen for. A rep who names features early has skipped the current state. A rep who hears a problem and never asks what it costs has skipped impact. Take a buyer who says onboarding is slow; the Gap Selling move is to ask how slow, since when, and what it costs, before any mention of the product. This example is illustrative.
What coaching Gap Selling involves
Gap Selling, written by Jim Keenan and taught by A Sales Growth Company, is hard to fake on a call, and easy to recite. A rep can recite current state, future state and the gap after one workshop and still pitch the moment a buyer mentions a problem. The distance between what a rep learned and what they do on a live call weeks later is what we call performance drift, and coaching on live deals is how a team closes it.
- 01Choose the behaviorThe element weakest across their deal reviews
- 02Brief before the buyer callOne question, said once out loud
- 03Observe the callWhat the buyer said, what the rep did next
- 04Describe, then askWhat happened, without a verdict
- 05Prescribe one changeAnd update the deal's Buyer Input Data
- 06Check for driftThree weeks later, on a different deal
Jim Keenan describes the coach's side in three steps: observe, describe, prescribe (A Sales Growth Company). Observe what the rep does on real calls. Describe it objectively ("when the buyer said the close slips, you moved to the demo"). Prescribe a different path. A Sales Growth Company's coaching system adds that coaching must be tied to defined selling behaviors from the methodology and to skill gaps found in real deals (A Sales Growth Company).
We run that inside the shape of any coaching session: brief before the buyer call, observe the call, debrief after it.
Behaviors to coach, by element
Pick one behavior per rep. The deal review usually tells you which one: the element that is still unconfirmed by the buyer on most of their deals.
| Element | Behavior to coach | What to listen for on the call | What changed looks like |
|---|---|---|---|
| Current state | Asks how the buyer does it today before naming a problem | A process described with steps and names | Rep can draw the buyer's process from memory |
| Problem | Stays on the problem and does not pitch | "Tell me more about that" after the first problem | Demo starts after the gap is agreed |
| Impact | Gets the buyer's number | A figure, a unit and a time period from the buyer | Proposals quote the buyer's numbers |
| Root cause | Asks why until it is fixable | A cause the buyer agrees with | Root cause maps to a row in the Problem Identification Chart |
| Cost of Inaction | Asks what happens if nothing changes | An answer about goals, people or standing | Deals stall less on "we'll wait" |
| Future state | Gets a measurable, dated outcome | "By Q3" or a number in the buyer's words | Success metric written in the deal notes |
| Next yes | Asks for a specific commitment | A dated, named next step | Every call ends with one |
The procedure: seven steps
1. Choose the behavior from the deal evidence
Look at the rep's last four or five deal reviews and find the element that is weakest across them. Good looks like: one behavior, named in the method's words, that the rep agrees with.
2. Brief before the next buyer call
Agree the one question the rep will ask on their next live call to practice the behavior. Say: "On Thursday's call, when she mentions the backlog, what will you ask to get her number?" Good looks like: a question in the rep's own words, written down.
3. Hear it once out loud
Have the rep say the question as they will on the call. One run is enough. Good looks like: the rep adjusting the wording themselves until it sounds like them.
4. Observe the call
Listen live or to the recording. Note what the buyer said and what the rep did next, word for word. Jim Keenan's first duty for a coach is to "keenly observe" (A Sales Growth Company). Good looks like: two or three quotes, with timestamps.
5. Describe, then ask
In the debrief, describe what happened without a verdict. Say: "At 14 minutes she said the backlog cost them overtime. You asked about their CRM next." Then ask: "What would you ask there now?" Good looks like: the rep finding the better question before you offer it.
6. Prescribe one change and check the BID
If the rep does not find it, offer one alternative. Then update the deal's Buyer Input Data from what the buyer said. Good looks like: one change for the next call, and a BID line that moved or did not.
7. Check for drift three weeks later
Pick a call from a few weeks on, on a different deal, and listen for the same behavior. Good looks like: the behavior there without a brief. If it is missing, the coaching is not finished.
Worked example
This example is illustrative. A rep, Dana, sells scheduling software to clinics. Her last five deal reviews show Impact unconfirmed on four: the numbers in her notes are her own estimates.
Week 1, brief: Dana has a second call with an operations director. They agree one question: "When a coordinator spends the morning rescheduling, what does that cost you in a month?" She says it once and changes "cost you" to "add up to," which sounds more like her.
Week 1, observe: on the call the director says the rescheduling is "a nightmare." Dana asks the question. The director says about 40 hours a week across the team, and roughly 30 missed appointments a month.
Week 1, debrief: the manager describes it back: "You got two numbers, both hers." Impact on that deal is now confirmed in the buyer's own numbers. Dana notices she never asked what happens if nothing changes. That becomes next week's brief.
Week 4, drift check: the manager listens to a first call Dana ran on a new deal without a brief. At 11 minutes the buyer mentions staff turnover. Dana asks what it costs them. The behavior is holding, so the coaching moves to Cost of Inaction.
A weekly session, minute by minute
The weekly one-on-one runs 20 to 30 minutes. A rhythm that holds up:
| Minutes | What happens | The manager's question |
|---|---|---|
| 0 to 5 | Drift check on last week's behavior | "Play me the moment from this week's call where it came up." |
| 5 to 12 | Debrief the call you observed | "What did the buyer say, and what did you ask next?" |
| 12 to 18 | Update the Buyer Input Data | "Which line moved because the buyer said it, and which is still your estimate?" |
| 18 to 25 | Brief the next buyer call | "What is the one question, and how will you say it?" |
Keep the deal list out of it. If the rep starts reporting status on six opportunities, park them for the pipeline meeting and go back to the one call.
Coaching past discovery: the demo and the proposal
Gap Selling does not stop at discovery, and the coaching should follow the deal. Two later moments drift most often.
The demo. The behavior to coach is showing only what closes the gap the buyer agreed to. Before the demo, ask the rep to list the two or three problems the buyer confirmed and the part of the product that answers each. Anything else stays out. In the debrief, ask: "Which problem did the buyer bring up again during the demo, and what did you show them?" A rep who toured every feature has gone back to selling the product.
The proposal. The behavior is writing the proposal in the buyer's words and numbers. Ask the rep to point to where the buyer's current state, impact and future state appear, and whose figures they are. A proposal that leads with the product, or quotes the rep's estimate of impact, is a sign that discovery was thinner than the deal record suggests. Price is the other test: a rep who has the buyer's number can set the price against what the problem costs, and a rep without it ends up defending a discount.
Problem-centric or needs-based: what the coach hears
The Gap Selling method focuses on the buyer's problem, where a needs-based approach starts from what the buyer says they want. On a call the two can sound alike for the first few minutes, and the difference is easiest to coach once you know where it shows.
A needs-based question is "What are you looking for in a new system?" The buyer answers with a wish list, and the rep matches features to it. A problem-centric question is "What happens today when a coordinator has to reschedule a full morning?" The buyer answers with a process, a cost and usually an emotion, and the rep has something to measure.
When you listen to a recording, mark the first question the rep asked after the buyer named a problem. If it was about requirements, features or timeline, the rep slipped into needs-based selling. If it was about how the problem happens, what it costs or why it started, the rep stayed with the problem.
The same distinction shows where the method fits best. Gap Selling suits sales where the buyer's problem has several causes and the cost of leaving it alone is not obvious. In a short transactional sale with a known need, the coaching still helps, but the rep will spend less time in the current state and the drift check should reflect that.
How to tell the coaching is working
Look for three changes, in this order.
- In the deal record. Impact and future state lines carry the buyer's figures, with a name and a date beside them, on more of the rep's deals.
- On the call. At the drift check, the behavior appears without a brief, on a deal you did not prepare together.
- In how deals stall. Fewer of the rep's deals stop at "we'll wait", because the cost of waiting was put on the table early.
If the record improves and the calls do not, the rep is filling in fields after the meeting. Go back to listening.
Where it goes wrong
Teaching the book again. The manager explains Gap Selling for 20 minutes. The rep knows it already. What they lack is the habit on a call.
Coaching every element. Seven things to improve means none of them change. Stay on one behavior per rep until it holds.
Coaching inside the pipeline meeting. A Sales Growth Company separates coaching from managing: pipeline updates track the work, coaching improves how reps sell, and it needs its own time (A Sales Growth Company).
Frequency without skill. In a study of 1,246 pharmaceutical sales reps, managers' coaching skill predicted goal attainment, and frequent coaching from less skilled managers was linked to worse results (Dahling et al. 2016, traced in our kickoff field study).
One session, then nothing. Spaced practice beats massed practice, with an effect size of 0.46 across 63 studies (Donovan and Radosevich 1999, in the same study). A single coaching session is a small workshop.
Coaching Gap Selling for every rep
A manager can coach one behavior with each rep. Briefing and debriefing every live call for every rep is more time than any manager has.
Keenan, our AI sales expert built on Gap Selling with A Sales Growth Company, briefs the rep before the buyer call and debriefs it after, by voice or video on a call. He scores the discovery against Gap Selling and holds the line on it; a rep who reports "they loved the demo" is asked for the buyer's number. Typing is the fallback when the rep cannot talk. He remembers every deal, so the brief for the next call starts where the last debrief ended.
Managers see which behavior is weakest across the team through Bryce, the manager coach, and the Gap Selling page shows the method on the platform. A Sales Growth Company's own Gap Selling training teaches the method itself.
Start with one rep and one behavior, such as asking for the buyer's number when the problem comes up. To hear how Keenan would brief that rep, talk him through a live deal.
FAQ
How do you coach a rep on Gap Selling?
Coach one Gap Selling behavior at a time on the rep's live deals. Pick the element that is weakest across their deal reviews, agree one question for the next buyer call, observe the call, describe what happened, and prescribe one change. Check the same behavior on a different call a few weeks later to see if it holds.
What is observe, describe, prescribe?
Observe, describe, prescribe is Jim Keenan's three-step model for the coach's side of sales coaching. The coach observes what the rep does on real calls, describes it objectively without blame, and prescribes an alternative path. He pairs it with the rep's side: absorb the feedback, adapt it, and practice until it becomes habit.
How often should managers coach Gap Selling?
Managers should coach Gap Selling weekly with each rep, tied to a live buyer call so there is something to brief and debrief. A Sales Growth Company recommends weekly one-on-one sessions focused on specific behaviors. Spacing matters: in Donovan and Radosevich's 1999 review of 63 studies, spaced practice beat massed practice, so short sessions over several weeks suit coaching better than one long workshop.
What is the hardest part of Gap Selling to coach?
Getting the buyer's number for impact is usually the hardest behavior to coach, because reps feel awkward asking and fill the gap with their own estimate. The estimate looks like evidence in the CRM, so it often goes unchallenged. A written standard that only counts numbers the buyer gave makes it visible.
Is Gap Selling training enough without coaching?
Gap Selling training teaches the method, but on its own it rarely changes what reps do on calls weeks later. A weekly coaching rhythm on live deals is what turns the method into habit and keeps it on the call after the workshop fades.
