What Makes a High Performance Team?

Monday, 20 July 2026

A high-performance team is a small group of people with complementary skills who share a clear purpose and hold themselves mutually accountable, and work together so that the group consistently produces more than the sum of its parts. What sets these teams apart is less the talent on the roster than how the members work together, with psychological safety as the foundation. This article works through what a team really is, why talent alone is not enough, the conditions that make the difference and what a leader does to create them.

What separates a high performance team from a group of talented people?

A high-performance team is not the same as a group of capable people who happen to share an office. In their classic Harvard Business Review article The Discipline of Teams, Jon Katzenbach and Douglas Smith define a real team as a small number of people with complementary skills who commit to a common purpose and hold themselves mutually accountable. They draw a sharp line between that and a working group, where members are responsible only for their own results. The difference is mutual accountability, because in a genuine team members own the collective outcome, not just their slice of it, which is what allows the group to produce results none of them could reach alone. Talent is the raw material, but it is this shared commitment that turns individuals into a team. That raises the obvious question of whether the mix of individuals is really what makes the difference.

Does it matter who is on the team?

Less than you would think. When Google studied nearly two hundred of its own teams in a project called Project Aristotle, it expected to find that the best teams were built from the best individuals. Instead, its researchers concluded that what mattered was far less about who is on the team and more about how the team worked together. Group norms and behaviour, not raw ability, separated the strong teams from the weak ones. The stakes are commercial as well as cultural, because engaged, well-functioning teams drive results. Indeed, Gallup’s analysis of more than 183,000 business units found that teams in the top quartile of engagement are 23 per cent more profitable than those in the bottom. If how a team works together is what counts, the natural next question is which condition matters most.

Why is psychological safety the foundation?

Of all the conditions Google identified, one stood out above the rest, and that was psychological safety, which means a shared belief that the team is safe for interpersonal risk taking. In a psychologically safe team, people ask the naive questions, admit the mistakes and challenge the plan without fear of being embarrassed or punished, which is exactly how problems surface early and good ideas get heard. It is worth being clear about what psychological safety is not: it is not niceness, comfort or lowered standards. Edmondson is emphatic that safe teams argue more, not less, since candour is the whole point. Psychological safety is the foundation, but it is not the whole structure.

What else do high performance teams have in common?

Above that foundation sit four more conditions that Google’s research found in its strongest teams. Dependability comes first, so members reliably do what they say they will and the team can trust that work will be finished to a high standard and on time. Structure and clarity follow, meaning clear roles, plans and goals so people know what is expected and how decisions get made. Then comes meaning, the sense that the work matters to each person, and impact, the belief that the team’s effort actually makes a difference. None of these is exotic, and that is the point, because high performance is built from ordinary conditions applied consistently rather than from a secret ingredient. The question for any organisation is who is responsible for putting those conditions in place.

What is the leader’s role in building one?

Teams do not become high-performing by accident, and the person with the most influence over whether they do is the leader. Leaders cannot manufacture performance directly by demanding it, but they can build the conditions that produce it, by setting a clear purpose, making it safe to speak up, holding the team to dependable standards and connecting the work to something that matters. The Australian Public Service Academy frames building and leading high performing teams as a core management capability, one that involves identifying the enablers and barriers and deliberately planning a path to a high performance culture. In practice that means a leader models the candour they want to see, responds well when someone raises a problem and protects the team’s focus. This is learnable work, which is why developing it deliberately makes such a difference.

Building the capability to lead high performance teams

The thread running through all of this is that high performance is created, not found, and the leader is the one who creates the conditions for it. Those skills, setting purpose, building safety, holding standards and sustaining momentum, are developed through practice and honest reflection rather than absorbed from a description.

That is what a focused program is for, and it is why AcademyGlobal (AG) runs its popular Leading High Performance Teamscourse, which helps managers turn the research on what makes teams work into the daily habits that build one. If you lead a team, or are about to, it is worth choosing a session that fits, so the next team you build is one that performs rather than just gathers.

Frequently asked questions

What is the difference between a group and a high performance team?

A group shares a space or a manager, but its members are accountable only for their own work. A high performance team shares a common purpose and holds itself mutually accountable for the collective result, so it produces more than its members could alone.

What is the most important factor in a high performance team?

Psychological safety, the shared belief that it is safe to speak up, ask questions and admit mistakes. Google’s Project Aristotle research found it was the single most important factor, because it lets a team surface problems and ideas early.

What are the five characteristics of an effective team?

Google’s research identified five: psychological safety, dependability, structure and clarity, meaning and impact. Psychological safety is the foundation upon which the other four build on.

Can any team become a high performance team?

Yes. Because performance depends on how a team works rather than who is on it, most teams can improve by building the right conditions, especially when the leader deliberately creates safety, clarity and accountability.
