TPB – Vanessa Druskat: Why Do Team Norms and Behavior Decide Team Success?
Teams are at the heart of how work gets done today. From product design to problem solving, most progress happens in groups. Yet even talented teams often struggle.
Some compete instead of cooperating, while others fall into habits that slow them down. The real difference between average and high-performing teams is not just skills or talent.
The set of shared rules guides how people treat one another, make decisions, and solve problems. These shared rules are team norms and behavior, shaping every part of teamwork.
Vanessa Druskat is an award-winning scholar, global speaker, and Associate Professor of Organizational Behaviour at the University of New Hampshire. She is the author of The Emotionally Intelligent Team, a book that introduces the Team Emotional Intelligence (Team EI) model based on over three decades of research.
Her research and articles in Harvard Business Review and MIT Sloan have been widely read, and she has advised major organizations worldwide.
This article will examine her insights on what makes teams succeed. You will learn how norms form, why belonging matters, and what leaders and members can do to create stronger teamwork.
We will also explore practical steps for handling poor behavior, protecting respect, and turning challenges into progress.
Vanessa Druskat’s interest in teams started with her own early experiences. She played soccer, joined cheerleading, and worked on farms from a young age. In those groups, she always felt supported and part of something bigger.
But when she stepped into the workplace, things changed. Competition was stronger than cooperation, and people often looked only for themselves. This sharp difference made her curious. Why did some teams bring out the best in people while others pushed them aside?

As a psychology student, Vanessa noticed that most research links team success to personality or skills. But her own life didn’t match that view.
She was the same person in supportive teams and in competitive ones. The difference came from social norms, the unspoken rules that shape how a team behaves.
Growing up in an international family also gave her unique insights. Vanessa moved across countries, including time in Kenya and later in Texas. Each place had its own expectations.
In British schools in Kenya, behavior had to be very formal. With African friends, social rules felt different. Texas schools added another layer. These shifts showed her that, like cultures, teams create rules that guide behavior.
When she studied workplace teams, Vanessa saw the same pattern. Even when teams did the same job, they worked in very different ways:
Another discovery came from watching emotions. Feelings spread quickly in groups and reveal tension or unity. Vanessa learned that strong teams manage both their norms and their emotions. This insight shaped her work on emotionally intelligent teams, now at the center of her research.
Norms are the unspoken rules that guide how people act in a team. They decide how members treat one another, share ideas, and respond when challenges arise. Every team has norms, but the best teams shape them intentionally instead of leaving them to chance.

When someone joins a new group, they quickly look around for cues. They watch who seems to lead and what behavior earns approval. This happens naturally, yet most people are not aware of it. Because of that, many teams end up with norms that grow without much thought.
Leaders have a key role in this process. Their job is not only to manage individuals but also to shape how members interact.
Strong leaders:
When leaders focus on the quality of relationships across the group, the team performs better.
Many organizations miss this point. They spend time and money hiring talented people, but forget to build the right culture. Even skilled members compete, argue, or pull back without clear norms. Talent matters, but teamwork depends on the rules that guide daily behavior.
High-performing teams take time to agree on how they want to work. The most effective norms often include:
When these practices are in place, trust grows, people feel valued, and skills combine more effectively. As a result, the team produces stronger results than anyone could alone.
Strong teams do not rely on luck. They set clear norms shaping how people interact and how work gets done.
These shared rules ensure everyone feels part of the group, respected for their strengths, and supported by others. Teams often face conflict, confusion, or a lack of focus without such norms.

Research shows that the best teams use norms in three key areas:
Belonging is the strongest human need in any group. People want to be known, valued, and supported. When this need is met, they give their best effort. When it is ignored, they hold back or become defensive. Respect is key here. You hardly notice it when it is present, but its absence damages teamwork immediately.
Every team faces unhelpful behavior at times. The best way to manage it is to agree on which actions are unacceptable early. Once those are clear, members can call them out respectfully when they appear.
This prevents problems from growing and keeps accountability strong. Clear and consistent norms build trust, motivation, and teamwork. With them, skills combine, ideas flow, and the group achieves far more than individuals could alone.
Every team will face moments when someone goes against agreed norms. It might be showing up late, cutting others off, or not delivering promised work.
When this happens, silence does not help. The best step is to give direct but respectful feedback. Asking what is happening and how to get back on track is far more effective than ignoring the issue.

It should not be the leader’s job alone to enforce norms. Teams work better when everyone plays a part. A simple approach is to assign a few members to watch for unhelpful behavior.
Their role is to point it out and help the group reset. This keeps accountability shared and avoids putting all the pressure on one person.
Teams often find that small signals make feedback easier. For example:
These methods work because they are simple and easy to use. Still, no system is perfect. Teams should check in often to see if their approach still works and adjust when needed.
People with more experience often help protect team culture. They know what has worked before and can guide others. But this only works if they are respected. When they feel ignored, they may grow frustrated and distance themselves, which hurts the team.
Unhelpful behavior can sometimes signal deeper issues or overlooked ideas. Instead of pushing it aside, strong teams use it to learn. Honest conversations help uncover concerns and bring out fresh thinking. This keeps everyone engaged and shows that all voices matter.
Strong teams do not happen by chance. They grow when people agree on how to work together and hold each other accountable. Skills and talent matter, but they only reach their full value when the group shares clear rules of respect and support.
Team norms and behavior guide every interaction. They shape how members share ideas, solve problems, and deal with conflict. When these norms are positive and intentional, trust builds, and people feel valued.
Even capable groups can compete, shut down, or lose focus when they are absent. Leaders have an important role, but responsibility should not rest on them alone. Teams work best when everyone helps protect the culture.
Simple steps, such as quick check-ins, agreed signals during meetings, or respectful feedback, make norms real and visible. Moreover, honest conversations about what works and needs to change keep the team moving forward.
Even conflict or poor behavior can become a chance to improve. Addressing it directly and respectfully often uncovers deeper issues or new ideas. The goal is always the same: to keep people engaged and motivated.
Success comes from creating an environment where members feel known, respected, and supported. When teams commit to strong norms, they achieve more together than anyone could alone.
Remote teams lack daily face-to-face contact. Clear norms keep everyone engaged, reduce distractions, and help meetings stay productive.
New members adjust faster when teams explain their norms openly. A short orientation or check-in helps set clear expectations.
Yes, norms should evolve as teams grow. Regular reviews ensure they still meet current goals and challenges.
Cultural background affects how people view respect, feedback, and teamwork. Teams need to discuss differences and agree on shared practices.
Strong norms promote open discussion and equal input. This leads to better choices and reduces the risk of groupthink.
