Team Cohesion: How to Build It, and What Actually Works

An offsite in the countryside, an escape room, after-work drinks… There’s no shortage of ways to bring a team together. They often make for a good moment. But three weeks later, meetings look exactly like they did before.

Why? Because team cohesion can’t be decreed in a day. It is built day after day, through trust, the quality of conversations and a shared direction. Here is what I’ve learned from working with teams, and what actually works.

What is team cohesion?

Team cohesion is a group’s ability to stay united around shared goals, to cooperate and to get through tensions without falling apart. It isn’t the absence of disagreement. It’s the confidence that you can disagree without damaging the relationship.

A few signs don’t lie: people dare to ask a “stupid” question, point out a mistake or say “I don’t agree” in a meeting. Information flows. People help each other without having to be asked.

What makes a team cohesive? What the research says

When Google studied what made its teams successful, in a research project called Aristotle, the most important factor was neither individual talent nor experience. It was psychological safety: the shared belief that you can speak up, suggest ideas and make mistakes without being embarrassed or pushed aside.

The concept was described by Amy Edmondson, a professor at Harvard. It has a very practical consequence: cohesion depends less on the activities you organize than on the way people talk to each other every day.

What are the five behaviors of a cohesive team?

The best-known model comes from Patrick Lencioni, in his book The Five Dysfunctions of a Team. According to him, a cohesive team:

• trusts one another, enough to admit mistakes and weaknesses;
• engages in open, constructive debate about ideas;
• commits to decisions, even after disagreeing;
• holds one another accountable, without waiting for the manager to do it;
• focuses on collective results rather than individual success.

Trust is the foundation: without it, the other four behaviors don’t hold. That’s why the levers below start with the way people talk to each other.

How can you improve team cohesion? 5 levers that work

1. Clarify the direction and the roles

A team bonds around something. When everyone knows where you are going, why, and who does what, many frictions disappear on their own. Take the time to restate the shared goal, and check that everyone understands it the same way.

2. Lead by example on psychological safety

The manager sets the tone. Admitting your own mistakes, asking questions rather than imposing answers, thanking the person who raises a problem: these simple gestures send a strong message. Here, you can speak up.

3. Get to know each other beyond job titles

We trust people, not job titles. With Stand Up For Passion, I’ve seen more than 200 people take the stage to share what drives them. Every time, the same effect: when someone shares a personal story, the way others see them changes. That’s why storytelling is at the heart of our team workshops.

4. Build feedback rituals

Cohesion needs upkeep. A regular team check-in where people say what’s working and what’s stuck, feedback given along the way rather than once a year: these rituals stop small misunderstandings from turning into real conflicts.

5. Work through tensions instead of avoiding them

The most cohesive teams aren’t the ones that never have conflict; they’re the ones that know how to talk about it. Often, what transforms a team is the conversation nobody dared to have. I write about this in Leadership Happens in Conversations.

Does team building improve team cohesion?

Team building is far from useless. It can spark something, on three conditions:

• it serves a clear goal (getting to know each other, learning to cooperate, preparing for a change);
• it leaves room to step back: what have we learned about how we work together?
• it is followed by concrete actions in the team’s day-to-day work.

Improv, for example, is a great training ground: you learn to listen, to build on someone else’s idea and to accept the unexpected. Exactly what a team needs on Monday morning. I explain the difference between the two in more detail in Team building vs team cohesion: what’s the difference?

The manager’s key role

All these levers have one thing in common: they go through the manager. The manager clarifies the direction, sets the example and opens the difficult conversations. So strengthening a team’s cohesion often starts with supporting the person who leads it. That’s exactly what our leadership and management training is for.
