When a star performer becomes your practice’s toughest challenge

Every architecture practice values talent.

That is as it should be. Talented people lift the work. They win client confidence. They solve hard problems. They create momentum, reputation and pride. In many practices, a highly capable senior person can become central to the way the business sees itself.

But there is a dangerous trade-off that appears in too many professional practices.

A high performer behaves badly, and the practice protects them because the work is good.

At first, the behaviour may be explained away. They are intense. They are passionate. They have high standards. They do not suffer fools. They are under pressure. They are difficult, yes, but brilliant.

The practice tells itself a story that makes tolerance feel commercially sensible.

That is the trap.

Talent can distort judgement

The more valuable someone appears to be, the harder it can be for leaders to judge their behaviour clearly.

A senior architect may produce excellent work. Clients may admire them. Their design judgement may be strong. They may carry important project knowledge or have influence inside the team.

This creates fear. What happens if they leave? What happens to the clients? What happens to the projects? What happens to the reputation of the practice?

These are legitimate concerns. But they can also become excuses.

When harmful behaviour is repeatedly tolerated because of talent, the issue is no longer only about that individual. It becomes a leadership problem.

The practice is effectively telling everyone else that standards are conditional.

The cost is paid by others

A disruptive high performer rarely carries the full cost of their own behaviour.

Others absorb it.

Team members work around them. Project leaders smooth over the tension. Principals intervene privately. Juniors become cautious. Capable people withdraw. Some leave. Others stay, but with less trust in leadership.

This cost is often hidden because the practice continues to function. The work goes out. Clients remain happy. The star keeps producing.

But internally, the culture changes.

People learn what is tolerated. They learn whose comfort matters most. They learn whether leadership will protect the team when doing so becomes inconvenient.

That learning is difficult to reverse.

Admiration complicates the issue

These situations are rarely simple because the star performer may not be disliked by everyone.

They may be charming. They may be funny. They may be generous at times. They may produce work that others genuinely admire. Some team members may defend them because they respect their talent or have benefited from their support.

This complexity can cause leaders to delay action.

They look for a balanced view. They hope the behaviour will settle. They try to manage around the person. They focus on the positive contribution. They tell themselves the situation is not affecting everyone.

But cultural harm does not need to affect everyone equally to be real.

If some people are intimidated, undermined or unfairly burdened, the practice has a problem.

From temperament to duty of care

There is a point where a difficult personality stops being a management inconvenience and becomes a duty-of-care issue.

This is the point leaders must not miss.

If someone’s behaviour erodes safety, trust or fairness, the practice has obligations that cannot be offset by talent. Strong performance does not cancel intimidation. Commercial value does not erase cultural harm. Creative brilliance does not justify unreasonable conduct.

In one situation I recall, a senior project architect was pressured into accepting responsibility for a problem they had not caused, largely to contain tension created by a high performer. By then, the issue was no longer about style, temperament or team fit. It had become a serious leadership and risk issue.

When the practice finally took specialist advice, the position became clearer. The relationship had to end.

The response inside the practice was mixed. Many were relieved. Some were upset. That is common. By the time a high performer has been protected for too long, the team may have built competing narratives around them.

But the central question remains straightforward:

Can this person remain in the practice without damaging the people and culture around them?

If the answer is no, their talent is no longer enough.

The stories leaders tell themselves

The greatest risk is often the story leadership starts to believe.

“We know they’re difficult, but they’re brilliant.”

“They don’t affect everyone.”

“People just need to learn how to deal with them.”

“We can’t afford to lose them.”

“The work would suffer without them.”

These statements may contain some truth. That is why they are persuasive.

But they also avoid the harder question: what is the cost of keeping them?

Not just the financial cost. The leadership cost. The cultural cost. The cost to trust. The cost to those who wonder whether the practice will protect them if protection becomes inconvenient.

A practice cannot build a healthy culture while maintaining an untouchable person.

What leaders need to do earlier

The best time to deal with this problem is before it becomes extreme.

That means setting behavioural expectations clearly, applying them consistently and intervening early when concerns appear. It means not waiting until the team is exhausted or a formal complaint is made. It means documenting concerns, seeking advice when needed and avoiding the temptation to treat talent as a mitigating factor for harm.

It also means separating performance conversations from personality debates.

The issue is not whether the person is brilliant, likeable or important. The issue is whether their behaviour is acceptable and sustainable within the practice.

That is a leadership question.

No one should be untouchable

Architecture practices depend on talent, but they also depend on trust.

If people believe that talent gives someone permission to behave badly, trust declines. If they believe leadership will avoid hard decisions to protect a star, confidence declines. If they see others carrying the cost of one person’s conduct, commitment declines.

No one person should become bigger than the standards of the practice.

Not because they are senior.

Not because they bring profile.

Not because clients like them.

Not because their work is excellent.

If their presence erodes safety, fairness or trust, they are no longer only a high performer.

They have become a structural risk.

And the longer leadership waits, the more expensive that risk becomes.
