Dan Martell's 1-3-1 rule is a simple, almost-free way to fix that — and build a real coaching culture. [![Daniel Marti](/images/team/daniel-marti.jpg)Daniel Marti ](/team/daniel-marti)· May 26, 20265 min read Share: [](https://www.linkedin.com/sharing/share-offsite/?url=https%3A%2F%2Ftransformery.ch%2Fblog%2F1-3-1-rule-sales-coaching) ![Minimal editorial diagram of the 1-3-1 coaching rule – one problem, three options, one recommendation as connected nodes](/images/blog/one-three-one-rule.jpg) Here's a pattern we see in almost every sales organisation we work with. The sales manager was promoted because they were a brilliant seller. Now they spend their week in forecast calls, pipeline reviews, and approvals. They track the numbers obsessively. What they almost never do — despite it being the single highest-leverage thing in the role — is coach. Not because they don't care. Because nobody gave them a simple, repeatable way to do it. So coaching collapses into "How's the Müller deal looking?" — which is inspection, not development. ## A small tool with a big effect Dan Martell — the SaaS founder and author of _Buy Back Your Time_ — uses a deceptively simple rule he calls **1-3-1**. It was built to stop founders from being the bottleneck for every decision. It works just as well for sales managers. The rule: when someone brings you a problem, they don't get to bring just the problem. They bring it in three parts. \- **1 — the problem.** Clearly defined. Not "the deal is stuck," but specifically _what_ is stuck and _why_. - **3 — three possible solutions.** They've thought it through and can argue three realistic options. - **1 — one recommendation.** Of those three, the one they'd choose — and why. Then — and only then — the manager engages. ## Why it changes the dynamic Look at what the old way trains. A rep hits a snag, walks over to the manager, describes it, and waits. The manager — being an ex-top-seller — solves it on the spot. Problem gone. Everyone moves on. Except something quietly corrosive just happened. The rep learned that thinking is the manager's job. Next time they'll come earlier, with less. The manager becomes the answer key. And the team's ability to think under pressure slowly atrophies. 1-3-1 flips it. The rep still gets help — but they've had to define the problem, generate options, and commit to a view before the conversation even starts. By the time they reach the manager, 80% of the developmental work is already done. The manager's role shifts from _solving_ to _coaching the thinking_: "Why did you rule out option two? What would have to be true for option three to work?" That is coaching. And it fits into the week the manager already has. ## The Augenhöhe point We talk a lot about leadership at eye level — _Augenhöhe_. 1-3-1 is one of the most practical expressions of it we know. It treats the rep as someone capable of thinking, not someone who needs to be told. It builds ownership instead of dependency. And it does something for the manager too: it pulls them out of the trap of being the smartest person on every deal, and into the role that actually grows a team. This connects directly to what we call Human-Centred Leadership — the side of leadership focused on unlocking individual potential rather than just driving output. A manager who solves every problem is optimising for today's deal. A manager who coaches the thinking is compounding the team's capability for every deal after it. ## Making it stick Two honest warnings. First, your reps will resist at the start. Coming with a fully-formed 1-3-1 is more work than coming with a complaint. Expect a few weeks of friction. Hold the line — kindly, but hold it. Second, the manager has to model it. If the manager still escalates every wobble to _their_ boss as a bare problem, the team will spot the hypocrisy immediately. 1-3-1 only works as a norm if it runs all the way up. The good news: it's almost free to implement. No software, no consultant required for the basic version, no reorganisation. It's a sentence: _"Bring me one problem, three options, one recommendation."_ Most sales transformations fail not because the strategy was wrong, but because the day-to-day behaviour never changed. 1-3-1 is a small behaviour. That's exactly why it works. ### Want sales managers who coach, not just inspect? We help DACH leadership teams install the small behaviours — like 1-3-1 — that turn sales managers into multipliers.
