Why High-Performing Individuals Don’t Always Make a High-Performing Team

They’re brilliant. So why aren’t they a great team?

Your team’s culture is nothing more than the habits your people repeat every day.

One of the biggest challenges I see in teams isn’t that people aren’t right for their roles. In fact, it’s often the opposite. I see smart, experienced, highly capable people, many of them star performers in their own right. They’re accountable, self-sufficient and good at what they do. But they’re great as individuals, not necessarily as a team.

What makes a high-performing team different?

A few weeks ago I saw how this played out. The team needed fresh ways of doing things: more ideas, more proactivity and more people willing to challenge assumptions and drive change. But that wasn’t what was happening.

People hesitated to speak up. They worried about sounding foolish or stepping on someone’s toes. They questioned whether their idea was good enough before they’d even shared it. So they put their heads down and focused on doing their own jobs well. It felt like such a missed opportunity. I could see just how much more this team could achieve together, and just how frustrated the leader was, because she could see it too.

The shift came when we stopped talking about what each individual needed to do and started talking about who they wanted to become as a team. When we genuinely see ourselves as part of a team, the question changes from “What if I sound stupid?” to “What’s in the best interests of the team?”

Sometimes that means asking the awkward question, challenging an idea, admitting you don’t know or volunteering for something that feels uncomfortable. It takes courage to stick your neck out despite the discomfort. But those are exactly the moments that shape how a team works together.

How everyday habits shape team culture

Teams don’t have habits. People do. Every day, individuals make hundreds of small choices: whether to ask for help, challenge an idea, involve someone else or stay silent. Each choice might seem insignificant on its own, but repeated across a team, those choices become the way things are done.

When enough people consistently practise behaviours that support the same way of working, those individual habits become the team’s Team Operating Habits™: small, observable behaviours that turn into shared norms. That’s what team culture looks like in practice. It’s not simply what the team says it values; it’s what people actually do, day after day.

Your team’s culture is nothing more than the habits your people repeat every day.

Why knowing what needs to change isn’t enough

Most teams don’t need another conversation about collaboration, accountability or innovation. They already know what needs to change. The harder part is following through when an old habit feels safer or easier: speaking up when you’d normally stay quiet, asking for input when you’d usually work alone, or raising a concern before it becomes a problem.

That’s the difference between agreeing on how you want to work together and actually becoming that team. It takes commitment and practice, repeatedly, in ordinary moments rather than only in workshops or planning sessions.

A question for your team

If you have capable people who aren’t yet operating as a cohesive, high-performing team, ask: What are we repeatedly doing—or avoiding—that makes it harder to work well together? And what is one small behaviour each of us could practise differently?
