Your Underperforming Sales Reps Aren’t the Problem
If the issue were purely the individual, performance would be consistent. But it is not. The same salesperson who struggles in one situation often performs significantly better in another. You have seen it during ride-alongs or when a manager is present. The conversation becomes more structured, objections are handled differently, and outcomes improve. Nothing about the person changed. Same rep. Same product. Same company. Different result.
If performance improves under certain conditions, then the issue is not capability. It is consistency. That distinction matters. A capability problem requires replacement. A consistency problem requires a different kind of solution. Most companies treat both the same—and end up cycling through people instead of fixing the underlying issue.
Variation in performance is not unusual—it is expected. McKinsey & Company has shown that in many organizations, top performers can produce significantly higher output than average performers even when operating within the same systems. That kind of spread does not happen randomly. It usually points to differences in how consistently behaviors are executed, not just differences in raw ability.
Most companies respond the same way. They invest in training, align the team, and reinforce the process. For a short period of time, performance improves. Then it fades. Not because the training was wrong, but because it was not sustained. Salesforce has shown that ongoing coaching and reinforcement are critical to maintaining sales performance, not just initial onboarding or training events. Training introduces the standard, but it does not maintain it.
This is why the same cycle keeps repeating. After training or a focused push, conversations improve, execution tightens, and results follow. But over time, details get skipped, structure loosens, and performance becomes inconsistent again. We have seen this play out the same way across different teams.
At that point, the issue becomes clearer. If a rep were truly incapable, you would not see moments of strong performance. But you do. That raises a more important question. You hired them to be a sales rep for your company for a reason. At some point, you believed they were capable of doing the job. And in many cases, that belief was justified—you have already seen them perform at a higher level. Just not consistently.
The difference between top performers and everyone else is rarely just knowledge. It is consistency of execution. Top performers tend to reinforce their own behavior. They adjust in real time, maintain structure, and stay aligned with what works. Everyone else depends on external reinforcement—and without it, performance drifts.
Because managers do not see most interactions, conclusions are often based on limited visibility. A strong ride-along creates confidence. A weak result later creates frustration. Without seeing the full pattern, the issue gets attributed to the individual instead of the environment. So the response becomes, “We need better people,” instead of, “We need more consistent execution.”
Once you recognize that inconsistency in performance—not lack of capability—is the real issue, the question changes. It is no longer, “Who do we need to replace?” It becomes, “What needs to change so that the better version of this rep shows up more consistently?” Across different companies, the same pattern appears. When the environment reinforces the right behaviors, performance improves. When it does not, performance varies. Which means the real issue is not the individual. It is the system surrounding them.
