A young engineer made a mistake that cost the company forty thousand dollars. He had been on the job for six weeks. He was smart, eager, and completely out of his depth on the project he had been assigned. His manager had assumed that a strong resume meant readiness. The engineer had never done this type of work before. He did not know what he did not know. The mistake was not a failure of effort or character. It was a failure of exposure. He had never been shown the specific risk that collapsed his project. When his manager walked into my office to discuss termination, I asked two questions. Had you ever explained this risk to him? The manager paused. No. Had you shadowed him through this process once before trusting him to execute it alone? No. The engineer was not incompetent. He was inexperienced. His manager had confused the two, and the company paid for the confusion.

Let me name the tension because every leader reading this has felt it. Someone on your team is not performing. You are frustrated. You are losing patience. You are wondering whether this person is capable of the work you hired them to do. That frustration is real, and it deserves attention. The question is whether your frustration is aimed at the right target. The hardest leadership judgment call is not whether to fire someone. It is whether to wait and invest. Most leaders err on the side of impatience. We assume that if someone cannot do the work, they are the wrong person for the role. That assumption costs organizations more than bad hires do. It costs them the people who would have become their best performers if someone had simply given them time, exposure, and coaching.

The distinction matters more than most leaders realize. Inexperience is a gap in exposure. The person has the raw ability. They have the judgment. They simply have not seen enough yet. They have not made enough mistakes to know where the risks live. They have not been trained on the specific systems, relationships, and patterns that the job requires. Inexperience is a training problem. It is solved by time, instruction, and repetition. Incompetence is different. Incompetence is a gap in judgment. The person has been exposed to the work. They have been trained. They have seen the risks and failed to recognize them anyway. The pattern is not that they do not know. It is that they do not learn. They make the same mistake twice. They apply the wrong framework to a familiar situation. They do not adjust when the evidence contradicts their approach. Experience will not fix incompetence because experience was never the missing ingredient.

Hebrews 5:12-14 (NLT) draws a similar distinction in the context of spiritual maturity. “You have been believers so long now that you ought to be teaching others. Instead, you need someone to teach you again the basic things about God’s word. You are like babies who need milk and cannot eat solid food. For someone who lives on milk is still an infant and doesn’t know how to do what is right. Solid food is for those who are mature, who through training have the skill to recognize the difference between right and wrong.” The writer of Hebrews is not criticizing the people for being beginners. He is criticizing them for staying beginners when they should have grown. There is no shame in needing milk. There is shame in needing milk when you have been given time to develop a taste for solid food. The passage reveals something about how growth works. Maturity comes through training, not through time alone. A person can sit in a role for years and never develop judgment if they have never been trained to exercise it.

This is where most leaders make the critical error. We assume that experience is the same thing as tenure. It is not. Tenure is how long someone has been in a role. Experience is what they have learned while being there. A person can have three years of experience or one year of experience repeated three times. The difference is whether they were trained, challenged, and stretched during that time. When a leader confuses tenure with experience, they blame the employee for not learning on their own. Learning is not an automatic byproduct of showing up. It requires instruction, feedback, and deliberate practice. If the leader has not provided those things, the gap belongs to the leader, not to the employee.

Paul makes a similar observation in 1 Corinthians 13:11 (NLT). “When I was a child, I spoke and thought and reasoned as a child. But when I grew up, I put away childish things.” Paul does not say he was punished for thinking like a child. He says he grew out of it. Growth is expected. Growth is normal. Growth requires time, and it requires the right environment. A child does not become an adult by being told to grow up. A child becomes an adult by being fed, taught, protected, and gradually given more responsibility as capacity develops. Leadership should work the same way. The question is whether your team members are children who have been given no food or adults who have refused to eat.

Let me make this practical because the distinction is useless without a framework for applying it. When you are frustrated with someone’s performance, ask four questions before you decide whether the problem is inexperience or incompetence.

First, have you been clear about what success looks like? Many performance problems are actually expectation problems. The employee does not know what you want because you have never stated it specifically. You have assumed they can read your mind. They cannot. Second, have you given them the tools and training to succeed? If the job requires a skill they have never learned, you cannot judge them for not having it. Either teach it or acknowledge that you hired for a skill set they do not possess. Third, have they made this same mistake before with the same coaching? This is the crucial diagnostic question. One mistake is inexperience. Two mistakes after clear feedback are something else. The heart of competence is the ability to adjust after correction. If an employee makes the same error after you have explained it, the gap is not exposure anymore. It is judgment. Fourth, does the employee recognize the gap? Inexperience shows up as surprise. The person did not know they made a mistake until you told them. They are genuinely shocked. Incompetence shows up as defensiveness or rationalization. The person either does not see the mistake or explains it away.

The distinction between inexperience and incompetence is also the distinction between training and reassignment. Train the inexperienced. They need time, coaching, and exposure to the patterns they have not seen yet. They will grow if you invest in them. Reassign the incompetent. They have had the chance to learn and have not learned. Keeping them in a role they cannot perform is not kindness. It is negligence that harms the team, the organization, and the employee who is set up to fail every day.

Jesus modeled this distinction in how he trained the disciples. He did not give them the same assignment twice. He gave them progressively harder assignments. First they watched him teach. Then he sent them out in pairs with instructions. Then he sent them out alone. Then he entrusted them with the leadership of the early church after his resurrection. Each stage built on the previous one. Jesus did not expect Peter to lead the church on the day Peter was called from the fishing boat. He gave Peter three years of exposure, correction, failure, and restoration. By the time Pentecost arrived, Peter’s inexperience had been replaced by the kind of training that only comes from walking through hard things with someone who will not give up on you.

The question this leaves you with is uncomfortable. How many people have you written off as incompetent who were simply inexperienced and underinvested? How many good people have left your team not because they could not do the work but because you did not do the work of developing them? The leader who blames the employee for inexperience is blaming the employee for a condition the leader was supposed to cure. Training is not optional in leadership. It is the job.

Leadership Challenge: Think of one person on your team whose performance has frustrated you recently. Before you decide what to do about them, work through the four diagnostic questions. Have you been clear about what success looks like? Have you given them the tools and training? Have they made the same mistake after clear feedback? Do they recognize the gap? Your answer will tell you whether they need more investment from you or a different role entirely.
