The truth is that most underperformance is not a single thing. It is a mix of skill gaps, unclear expectations, poor role fit, and sometimes plain burnout. Coaching fixes some of these. Re-seating fixes others. Get the diagnosis wrong and you either waste months coaching someone who was never going to succeed in that seat, or you move someone out of a role they could have grown into with the right support.
Here is a practical way to tell the two apart before you act.
Start with the gap, not the symptom
The first mistake founders make is reacting to the symptom, missed deadlines, a flat sales month, a tense client call, instead of asking what is actually causing it.
Write down the specific gap. Not "they're not performing" but "they miss deadlines on multi-step projects" or "they freeze in negotiation conversations." A vague complaint cannot be coached or solved. A specific gap can be tested.
Once you have the gap named, ask a second question: is this a skill the person does not yet have, or a mode of working that does not suit them. Those are different problems with different fixes.
The five-question test
Before you decide to coach or re-seat, run the person through these five questions honestly.
Have they done this well before, anywhere. If yes, something changed, workload, manager, role scope, and that is worth investigating before assuming a capability problem.
Is the gap about knowledge or about temperament. A knowledge gap (they do not know how to run a discovery call) is coachable in weeks. A temperament mismatch (they are naturally deliberate and careful, but the role demands fast improvisation under pressure) is much harder to coach away, because you are asking someone to work against their wiring every single day.
Have they had a real chance, meaning clear expectations, adequate time, and actual feedback, not just vague disappointment. Many "underperformers" have never been told specifically what good looks like.
Does the rest of the team see the same pattern, or is this isolated to one manager or one type of task. A pattern across contexts points to fit. A pattern in one context points to a specific fixable friction.
Would you be excited to see them succeed in a different seat at your company. If the honest answer is yes, that is your answer, moving them is not a demotion, it is better allocation.
When coaching is the right call
Coaching works when the gap is narrow, the person has shown capability elsewhere, and the fix is teachable. Someone who is technically strong but avoids difficult conversations can be coached through scripts, roleplay, and repetition. Someone who is disorganised but detail-capable can be coached with better systems and checkpoints.
Good coaching has a shape. It names the specific behaviour to change, sets a short timeframe (four to six weeks, not "let's see how it goes"), and includes a clear signal for what success looks like at the end. Open-ended coaching with no endpoint is usually a sign you already suspect this is not fixable and are avoiding the harder conversation.
When re-seating is the right call
Re-seating is right when the mismatch is structural rather than a skills gap. A brilliant closer who is miserable and mediocre managing people should not be coached into becoming a manager, they should be moved into a role that uses their actual strength. A meticulous operator forced into fast, ambiguous sales conversations will struggle no matter how much coaching you throw at it, because the role is fighting their natural working style.
This is also where founders often confuse re-seating with failure. It is not. Re-seating someone into a role that fits how they actually work is frequently the highest-leverage move you can make, for them and for the business. Some of the best hires I have seen were people who were "underperforming" in one seat and became genuinely excellent within eight weeks of moving to another.
Building the habit into how you manage
The founders who get this right do not wait for a crisis to ask these questions. They build a habit of understanding how each person on the team actually works, what energises them, what drains them, where their judgement is strongest, before performance becomes a problem.
This is where a tool like TalentLens is useful. It gives you a clear, plain-language read on how someone works, their strengths, their blind spots, and how well they fit a given role, so you are not guessing when a performance issue shows up. Instead of debating in the abstract whether someone needs coaching or a new seat, you have an actual picture of their working style to test the decision against. It sits alongside your own judgement and the conversations you are already having, not instead of them.
Make the call, then commit
Whichever way you decide, commit fully. Half-hearted coaching wastes everyone's time and half-hearted re-seating (moving someone without a real plan for their new role) just relocates the same problem. Name the gap, run it through the five questions, choose a path, and give it a real chance to work before you revisit it.
