The Hidden "Hill" Killing Your Sales Team's Productivity

When a rep isn't hitting their number, what's the first thing most leaders do?

Add training. Schedule more coaching sessions. Roll out a new methodology. Assume it's a skill problem and throw resources at closing the gap.

Sometimes that's exactly right. But according to Gartner research, it's often wrong. And the misdiagnosis is costing companies in ways that don't show up until it's too late.

Skill, Will, and Hill

At this year’s Gartner CSO conference, analyst Danielle McKinley introduced a diagnostic framework worth putting on your wall: every seller productivity problem falls into one of three categories.

Skill: Can they do it? Do reps have the knowledge, product fluency, and process skills to execute?

‍Will: Do they want to? Are reps bought in, confident, and engaged enough to put in the effort?

Hill: Does the system make it hard? Are reps fighting bad tooling, unclear process, inconsistent messaging, or administrative burden that makes good performance structurally difficult?

The Gartner data that should reframe how you think about underperformance: 78% of sellers say they're overwhelmed. And overwhelmed sellers are 45% less likely to hit quota.

That's not a Skill problem. That's not a Will problem. That's a Hill.

The Misdiagnosis Trap

Here's where most sales organizations go wrong. Skill problems are visible and fixable. You can run a training, measure a certification, check a box. So leaders over-rotate toward Skill interventions even when the real blocker is environmental.

You can train a rep on a perfect discovery framework, but if their CRM is a mess and they're spending hours on manual data entry before every call, the training won't stick. The Hill is in the way.

This is why 52% of CSOs say their sellers struggle to adapt during periods of organizational change. The barrier usually isn't that reps don't understand what's being asked of them. It's that the environment hasn't caught up—the Hill got taller.

Manager Julia's Real Problem

Julia the manager doing everything right: running 1:1s, coaching actively, investing in her people. Her team misses quota, but five of eight reps are hitting individual targets. She's developing talent, not hiding behind one hero rep.

But the Skill/Will/Hill framework illuminates something new about her situation.

Some of Julia's reps aren't facing a skill gap or a motivation issue. They're hitting a structural obstacle. Maybe it's a territory problem. Maybe it's a broken handoff from marketing. Maybe messaging on a specific product line is making every discovery call harder than it should be.

Julia can probably sense this. But she can't diagnose it clearly, because she's fighting her own Hill.

To understand what's actually happening with each rep, she'd need to pull data from four, five, maybe six different systems, and then synthesize it into something coherent, then figure out what conversation to have and when to have it. Most weeks, she doesn't get there. Not because she doesn't care, but because the system makes it structurally difficult.

So the Hill blocking her reps goes undiagnosed. And unaddressed.

The Compounding Problem

This is what makes the Hill so dangerous as a productivity blocker: it compounds.

A rep with a skill gap gets training and often improves. A rep with a will problem gets coaching and often re-engages. But a rep hitting a structural Hill—with a manager too buried in their own administrative load to identify and remove it—just keeps grinding. Performance slowly degrades. The rep becomes a flight risk. Then they leave.

Meanwhile, your training budget grew, your methodology rollout succeeded, and nobody can figure out why performance didn't follow.

What Removing the Hill Actually Looks Like

The fix isn't another system. It's removing friction from the diagnostic layer; specifically, from the manager's ability to see what's actually happening with each rep, surface the pattern, and act on it.

When Julia can walk into a 1:1 already knowing which reps are facing a Hill-type blocker versus a Skill or Will issue, the conversation changes completely. Instead of generic check-ins, she's running targeted interventions. Instead of guessing, she's diagnosing.

The framework is simple. The data needed to apply it isn't complicated. What's been missing is the infrastructure that makes that data accessible to managers at the moment they need it.
