When teams work in silos, the problem is rarely that people do not care. More often, it is that each team becomes focused on its own pressures, targets, deadlines and ways of working. Over time, this creates separation. People stop asking questions, assumptions grow, trust weakens and collaboration becomes harder than it needs to be.

Silos can show up in small but damaging ways. One team does not share information early enough. Another team feels excluded from decisions. Leaders give different messages. People become protective of their own priorities. Before long, colleagues who should be working together start to see each other as obstacles.

Everything starts with communication. If communication between teams is unclear, rushed, defensive or inconsistent, collaboration will suffer. If communication is open, respectful and human, teams are far more likely to solve problems together.

Start by understanding why the silos exist

It is tempting to tell teams they need to “collaborate better”, but that rarely changes anything on its own. Leaders first need to understand what is causing the separation.

Sometimes silos are created by structure. Teams may be measured against different targets, using different systems or reporting to different leaders. Sometimes they are created by history. A previous disagreement, poor handover or broken promise can leave people cautious. Sometimes they are created by communication habits. Teams may only speak when something has gone wrong, which means every conversation starts from a place of tension.

Improving collaboration starts with curiosity. What is each team trying to achieve? Where are the pressures? What information is missing? Where do people feel misunderstood? These questions help move the conversation away from blame and towards shared understanding.

Create a shared purpose

Teams collaborate better when they can see what they are working towards together. Without a shared purpose, each team naturally protects its own priorities.

A useful question for leaders is: what do these teams need to achieve that they cannot achieve separately?

That might be a better customer experience, smoother project delivery, safer decision-making, stronger internal communication or more consistent leadership. Once people can see the bigger picture, they are more likely to look beyond their own department.

This is where leadership communication across a business becomes so important. If leaders communicate in disconnected ways, teams will act in disconnected ways. When leaders align around a clear purpose, repeat the same core message and explain how each team contributes, collaboration becomes easier to practise.

Build relationships before there is a problem

Many cross-team relationships only come alive when there is pressure. A deadline is missed. A customer complains. A handover fails. By then, people are already frustrated.

Strong collaboration is built before the difficult moment arrives.

Teams need opportunities to engage with each other as people, not just job titles. This does not need to be complicated. Joint planning sessions, project reviews, shared learning conversations and regular check-ins can all help. The aim is to create familiarity, trust and a better understanding of how each team works.

When people know each other, they are more likely to pick up the phone, ask a better question and assume positive intent. When they do not know each other, they are more likely to rely on email, make assumptions and protect themselves.

Make listening part of the process

Collaboration breaks down quickly when teams listen only to reply, defend or justify. This is why listening is such an important skill at work. It slows the conversation down and helps people understand the reality of another team’s experience.

Good listening sounds simple, but under pressure it takes real discipline. It means asking questions before making judgements. It means checking understanding before responding. It means being willing to hear that your team’s actions may have created difficulty for someone else.

This is where Debra Stevens’ Stand Out framework is useful. Teams need to Engage, Listen, Empathise, Collaborate and Inspire. Collaboration is not just a process skill. It is a human skill. People need to feel heard before they are willing to work differently together.

Deal with the conversations people are avoiding

Silos often continue because people avoid the conversations that would break them down.

A team may be frustrated about poor communication but never say it directly. A manager may know there is tension between departments but hope it settles down on its own. People may talk about each other instead of with each other.

This is where difficult conversations matter. Collaboration improves when teams can speak honestly and respectfully about what is not working. That includes naming repeated problems, exploring impact and agreeing what needs to change.

The tone of these conversations matters. The aim is not to win, blame or prove who is right. The aim is to understand what is getting in the way and agree a better way of working.

Turn collaboration into behaviour, not a slogan

Many organisations say they value collaboration, but their everyday behaviours tell a different story. Meetings stay departmental. Information is held back. Leaders reward individual team performance but not shared outcomes. People are told to collaborate, but they are not given the skills or conditions to do it well.

To create behaviour change in leadership teams and across departments, collaboration has to be practised. People need to work on real scenarios, reflect on their communication habits and try new ways of handling tension, challenge and shared decision-making.

This is why experiential learning is so effective. Information alone does not change behaviour. People need to experience different conversations, notice their own patterns and build the confidence to communicate differently in real workplace situations.

How DSTC helps teams work better together

DSTC helps organisations improve collaboration by focusing on the communication behaviours underneath the problem. Through practical, experiential workshops, teams can explore how they engage, listen, empathise, collaborate and inspire across boundaries.

This is not about telling people to be nicer to each other. It is about helping teams communicate more clearly, handle tension more honestly and build the trust needed to work together properly.

When teams move out of silos, they do more than share information. They build stronger relationships, make better decisions and create a healthier working culture.

Collaboration improves when people stop protecting their own corner and start communicating with a shared purpose.
