Why Your Best Performer Shouldn't Always Be Your Leader

There’s a pattern that shows up in organisations again and again.

Someone is exceptional at what they do. They’re technically brilliant. They deliver consistently. They’re recognised as one of the best in their field.

So naturally, they get promoted. They move into leadership.

And that’s where things sometimes start to unravel.

The Individual Contributor Trap

We often assume that the skills that make someone successful in their role will translate naturally into leadership.

But leadership is a different job.

Being a high-performing individual contributor is about expertise. Leadership is about enabling others.

Those are not the same thing.

The behaviours that create individual success — depth of focus, personal ownership, high standards for your own output — can actively work against leadership effectiveness if they’re not balanced with something else.

A leader who focuses primarily on their own contribution often struggles to delegate. A leader whose identity is built around expertise can find it threatening when others challenge their thinking. A leader who has always delivered through individual effort may not know how to develop capability in others.

A Lesson from Formula 1

Adrian Newey is widely regarded as one of the greatest aerodynamicists in Formula 1 history. His designs have contributed to championship-winning cars across decades. A true specialist. A genius in his field.

Leading a small team of highly skilled engineers — shared language, deep expertise, clear focus — that’s his environment.

But scaling into leading a large, complex organisation is something else entirely.

Because once you move into that level of leadership, the role changes. It’s no longer about your technical brilliance. It’s about aligning large teams, managing complexity, making decisions across functions you may not fully understand, and creating an environment where others can perform.

That requires a completely different skillset.

The Leadership Shift Most People Miss

The moment someone moves from individual contributor to leader, their measure of success changes.

Before: How well did I perform?

After: How well did the people I lead perform?

That shift is significant. And for many high performers, it’s uncomfortable.

Because it means releasing control. Trusting others to do things differently — and sometimes less perfectly — than you would. Measuring your success through someone else’s growth.

Not every brilliant individual has the appetite for that shift. Not every expert wants to lead. And organisations that assume otherwise — that promotion is the natural reward for performance — often end up with frustrated leaders and underperforming teams.

What Organisations Can Do

The solution isn’t to stop promoting high performers. It’s to do it more thoughtfully.

Separate career progression from management. Create routes to seniority that don’t require people to lead teams. Some of your best performers will thrive as senior specialists or technical leads. Giving them a management role because it’s the only way up is a design problem.

Invest in the transition. Moving into leadership for the first time is one of the most significant professional shifts anyone makes. It deserves serious development support — not a title change and good luck.

Assess leadership potential separately from performance. Someone can be excellent at their job and have genuine leadership potential. Or they can be excellent at their job and have very little interest in, or aptitude for, leading others. Those are different conversations.

The organisations that get this right tend to have leaders who actually want to lead — not just people who were good enough at something else to get promoted into it.

That distinction matters more than most organisations acknowledge.
