Sales Coaching Models: Use One to Diagnose, One to Talk, and a 30-Day Loop

A manager who coaches when the week allows it is not coaching, they are reacting. The slot survives a quiet fortnight and dies the first time a deal catches fire at month end, and the rep learns which one was real.

What follows is a thirty-day loop for one rep and one behaviour, built from two of the better-known coaching models used for the two different jobs they are actually good at. Budget roughly half an hour of conversation per rep per week plus a similar amount of listening beforehand. Skip the certification, skip the template pack.

The Models Are One Model With Four Haircuts

Start here, because most of the time spent choosing a coaching model is wasted. Matt Bolian, writing for Supered in June 2026, compares GROW, OSKAR, CLEAR and FUEL and concludes they run the same underlying sequence. His verdict is blunt: the acronyms are "the marketing", the shared arc is the product, and "the model you pick matters far less than whether you run one consistently".

Alex Kudinov, a master-credentialled coach writing for Tandem Coaching in April 2026, makes the complementary point from the professional coaching side. Models supply architecture, deciding which skill comes in what order, but they do not tell a coach how to listen, what to ask or when to stay quiet. He calls running the phases mechanically the "checklist trap", and it is the exact failure a sales organisation produces when it buys training and inspects adoption.

So this sprint uses two frameworks for two distinct purposes. One diagnoses what to work on. The other structures the conversation. Neither is the point.

The Sprint on One Page

When	What you do	What you are testing
Days 1 to 3	Sort the gap into effort, knowledge or skill	Which lever is worth pulling at all
Days 4 to 7	Listen to two recordings from that stage	The precise second the conversation turns
Week 2	Hold the first structured session	One behaviour, one written commitment
Week 3	Mark three fresh calls against the commitment	Whether anything moved
Week 4	Short second session, then a call on what next	Continue, switch lever, or stop

Days 1 to 3: Find the Lever Before You Find the Fault

Winning by Design's REKS blueprint, published in May 2022, sorts a performance problem into Results, Effort, Knowledge and Skills, and exists to "help leaders diagnose performance issues and coach the right levers". Its most useful instruction is a constraint: "Coaching should target one lever at a time to avoid overwhelm."

Begin from a result, something countable such as a weak conversion from first meeting to second. Then run three checks before you form any view about the rep.

• Effort. Open the calendar and the activity record. Is there enough of the thing happening to produce the outcome at any skill level?
• Knowledge. Ask two direct questions about the product, the buyer or the usual objection. If the answers are thin, the problem is not on the call.
• Skill. Only reachable once the first two come back clean, and you will not confirm it until you listen.

What this step cannot do: tell you which skill is weak. It only narrows the field to one of three, and narrowing is the entire job for three days.

Days 4 to 7: Collect a Timestamp, Not an Impression

Choose two recordings from the stage you identified. Write down the exact words and the minute mark, never a summary of how the call felt. HubSpot's coaching guide gives the reason in five words worth remembering: "Opinion-based coaching is the enemy of buy-in." A rep can argue with a characterisation of their performance. Nobody argues with their own sentence played back at the eleven-minute mark.

Our routine for pulling a usable clip from a recording keeps this to twenty minutes rather than an afternoon. What this step cannot do: establish that the behaviour is typical. Two calls are a sample, and treating them as a verdict is how a rep stops volunteering recordings.

Week 2: One Conversation, One Commitment

Run the session on the four-stage structure HubSpot sets out, where the conversation moves from what success looks like, to where things honestly stand, to the approaches available, to the single thing the rep will do before you next speak.

Two mechanics decide whether it works. Play the clip during the second stage, and let the rep say what they notice before you offer anything. Then close with one written sentence naming the behaviour and the date, in the rep's own wording. What this step cannot do: create a habit. A commitment is an intention with a deadline attached, and the following week is where it either survives or does not. Fit it inside the slot described in our thirty-minute weekly system rather than adding another meeting.

Week 3: Mark Three Calls, and Say So Within a Day

Listen to three calls recorded after the session and look for one thing only. Mark each as done, partly done, or absent, and send the marks inside twenty-four hours with a line about the best moment you heard. Speed matters more than depth here, because feedback arriving a fortnight later is a report card rather than coaching.

If the behaviour is absent from all three, resist the obvious conclusion. Ask what got in the way first. Often the obstacle is the call structure, the tooling, or an account list that makes the behaviour impossible, not the rep's capability.

Week 4: Keep It, Switch, or Stop

Hold a short second session on what weeks two and three produced, then choose one of three outcomes: stay on the same behaviour, move to the next lever, or stop coaching this rep on this lever for now. Write the call evidence for whichever you choose.

Write two sentences, one for the rep and one for your own record, naming the behaviour and the specific evidence it rests on. That record is what stops the next sprint drifting onto a new target because the month changed, and it protects a rep from a manager with a short memory. If several reps need this, stagger the sprints so you never run more than two at once, and read our note on how many reps one coach can genuinely carry before committing to a schedule.

Three Things Not to Do

• Work three behaviours at once. The rep will deliver none of them, and you will not know which one failed.
• Produce a scorecard in the first session. It converts a conversation into an assessment and the rep starts managing the score.
• Import a benchmark. Published coaching statistics conflict with each other and frequently trace back to nothing citable. HubSpot's guide attributes the strongest claim about where coaching pays off to The Challenger Sale authors and to Sales Management Association research, pointing at the middle of the team rather than the top or bottom. Use that as a direction for who to coach, and get your numbers from your own calls.

The Acronym Is the Least Important Decision You Will Make

Here is the position: the whole market for coaching models is solving a problem most sales organisations do not have. The two sources above agree from different professions, one selling sales enablement and one holding a coaching credential, and neither has an incentive to say the framework hardly matters. What does matter, on both accounts, is whether the loop runs every week and whether the coach can do the things no model specifies, which is listening and knowing when to stop talking.

The practical implication is uncomfortable for a leader with a budget. The money is better spent on protecting the time than on buying the method. A manager who runs a mediocre structure weekly for a quarter will beat a manager who runs an excellent one twice, and that is not a training problem, it is a calendar problem, which is the same argument we make in coaching that is really deal inspection.

A manager who has never coached anybody is the exception. If the structure is genuinely unfamiliar, the model is doing real work as scaffolding, and the first six sessions will go better with it than without. The argument is against shopping between models, not against using one. Pick the simplest, run it for a quarter, and judge the loop rather than the acronym.

Where It Falls Over

• No time exists. Then run it with one rep rather than four. A single completed sprint beats four abandoned ones.
• The rep will not share calls. Make it mutual and go first: review one of your own recordings in front of the team before you ask for theirs.
• Three reps are weak at the same stage. That is not a coaching problem. Look at targeting and message, starting with writing the ideal customer profile as a checklist rather than a feeling.

Run one sprint this month with one person. Judge it first on whether the behaviour appears in three new recordings, and only later on the stage conversion it was meant to move, which needs a full cycle to show anything. No coaching loop guarantees attainment, and anyone who tells you otherwise is selling the loop.
