One of the most valuable lessons my mentor Paul shared with me is deceptively simple. He told me there are really only three reasons why someone can’t do a job:
- It’s too hard.
- They haven’t been trained.
- They aren’t qualified.
That’s it. Just three.
When he first said this, I’ll admit I pushed back a little. Life and business both feel more complicated than that. Surely there are endless reasons someone can fail at a role or struggle with a responsibility. But the more I sat with it, and the more I tested it in my own companies, the more I realized how right he was.
Let me walk through each of the three and why they matter for leaders, business owners, and anyone who has ever had to rely on another person to get results.
1. It’s Too Hard
Sometimes the task or job itself is just too difficult for one person to handle. This isn’t about lack of effort or even lack of talent. It’s about the scope of the work being unreasonable.
I once had a team member who was putting in long hours, genuinely cared about the mission, and had all the right instincts. But they were drowning. No amount of pep talks, time-management tips, or productivity hacks were going to fix it. The work itself was overwhelming.
In those cases, the job has to be redesigned, not the person. Maybe the workload needs to be spread across more people. Maybe automation or better systems can take on part of it. Maybe the expectations was unrealistic from the start.
If it’s too hard, leaders have to face the truth: no one, no matter how talented, is going to succeed long term in an impossible role.
2. They Haven’t Been Trained
This one is deceptively common. Many of us assume that once someone is “hired,” they should already know how to perform every task that falls under their job description. But even the smartest, most capable hires still need guidance in the context of your company, your culture, and your systems.
I’ve made the mistake of skipping training before. I once brought in a very capable specialist. On paper, they were perfect. In reality, they struggled to deliver the results I expected. At first I thought maybe they weren’t as good as they seemed. But the truth was I hadn’t invested the time to show them how we do things here. Once I corrected that and gave them proper training, their performance soared.
Training is not optional. It’s the bridge between potential and performance. And when leaders ignore it, they confuse a training issue with a talent issue.
(And if you think training is expensive, try running a company where you’re the one doing all the jobs you don’t know how to do. Trust me, I’ve been there. My attempts at graphic design still look like a 6th grader with Photoshop discovered the “spray paint” tool.)
3. They Aren’t Qualified
The third reason is the toughest, and it’s also the one leaders often want to avoid confronting. Sometimes a person simply isn’t qualified for the role. They might not have the skill set, the temperament, or the mindset required to succeed, no matter how much training you give them or how much you lighten their workload.
This doesn’t mean they’re a bad person or even a bad employee. It just means they’re in the wrong seat.
I’ve had to make this call before, and it’s never easy. In fact, some of the hardest conversations of my career has been when I had to tell someone they weren’t a fit for the role. But what I’ve found is that keeping someone in a role they’re not qualified for hurts everyone. It hurts the business. It hurts the team. And it hurts the individual, because they’re constantly struggling, stressed, and feeling like they’re falling short.
When leaders face this honestly, it creates room for the person to move into a role that better matches their qualifications, whether inside the company or elsewhere.
Why This Framework Matters
The beauty of Paul’s lesson is that it simplifies what can feel like a messy, emotional process into something clear and actionable. When someone on your team is struggling, instead of throwing up your hands in frustration or layering on vague complaints, you can stop and ask:
- Is this too hard?
- Have they been trained?
- Are they qualified?
Answering those questions gives you direction. If it’s too hard, you redesign the job. If they haven’t been trained, you train them. If they aren’t qualified, you help them transition.
As leaders, it’s easy to personalize the struggle. We can think, “This person is lazy” or “They just don’t care.” In my experience, that’s rarely the case. Most people genuinely want to do good work. They want to succeed. They want to contribute. If they can’t, one of these three reasons is usually why.
Paul’s framework has stayed with me because of its clarity. Business will always be filled with complexity, but clarity is what helps us make progress. When you understand the three reasons someone can’t do a job, you stop guessing. You stop spinning your wheels. You know exactly where to focus your energy as a leader.
And in leadership, clarity is one of the greatest gift you can give, both to your team and to yourself.
