Why Silos Develop in Expertise-Heavy Organisations

Years ago, when I was a fledgling marketer in the pharmaceutical industry, I found myself sitting in a pre-commercialisation meeting with colleagues from Medical Affairs, Regulatory Affairs, Commercial, Market Access and Clinical Development.

We were discussing the same product, the same data, and the same objective. Yet by the end of the meeting, it felt as though we had all attended different discussions.

The Medical team was focused on scientific integrity and evidence, regulatory was focused on compliance and risk, market Access was focused on payer requirements, and I was focused on adoption and patient impact.

Everyone was intelligent. Everyone was acting in good faith. And everyone cared deeply about achieving the right outcome.

And yet progress was painfully slow.

It wasn't because people were unwilling to collaborate. It was because each person was interpreting the situation through the lens of their own expertise. More importantly, each person believed their lens was the one that mattered most.

The Medical team believed scientific integrity had to come first.

Regulatory believed compliance and risk had to come first.

Commercial believed patient access and adoption had to come first.

Market Access believed payer requirements had to come first.

None of them were wrong.

The problem was that everyone was trying to establish priority rather than understand why the others were prioritising something different.

At the time, I remember feeling frustrated. Surely we were all looking at the same information. What I failed to appreciate was that information and interpretation are not the same thing.

Each function was seeing something different because each function had been trained to see something different.

That experience taught me an important and valuable lesson: The greatest barriers inside expert organisations are rarely personal.

More often, they are perceptual.

Expertise Creates Boundaries

Most people think silos are caused by organisational charts. They're not. The organisational chart simply makes them visible. The real cause runs much deeper.

In expertise-heavy organisations, silos emerge because people are trained to see the world differently.

Scientists, clinicians, engineers, finance professionals, lawyers, regulators, researchers, IT specialists and policy experts are all taught to solve different problems, measure success differently, manage risk differently and value different types of evidence.

Over time, these differences become more than expertise. They become identity. And that's where the trouble starts.

Experts spend years developing deep knowledge within a specific discipline. That depth is valuable. It is often what makes organisations successful. But expertise comes with an unintended consequence: the more specialised our knowledge becomes, the more likely we are to interpret problems through the lens of our own expertise.

Researchers have described this as a form of organisational silofication, where groups become separated by the boundaries of their own knowledge and perspectives. When left unchecked, these invisible boundaries restrict collaboration, knowledge sharing and organisational learning. (MDPI)

People don't deliberately create silos. They simply become convinced that their perspective is the most important one.

Functional Structures Reinforce the Problem

Most expertise-heavy organisations are organised by function.

Research reports to research, policy reports to policy, finance reports to finance, engineering reports to engineering. The structure makes perfect sense operationally. It creates efficiency, consistency and professional development.

The problem is that people spend most of their time talking to others who think like they do. The organisation unintentionally rewards local optimisation.

People become highly effective at solving problems within their own area whilst becoming increasingly disconnected from the needs, pressures and priorities of other functions.

Over time, the organisation develops multiple versions of reality. Each one is technically correct. None of them are complete.

The More Intelligent the People, the Stronger the Silos

This is one of the great ironies of expert organisations.

The smarter the people are, the more likely they are to defend their perspective.

Experts are trained to evaluate evidence, identify flaws in reasoning, challenge assumptions and defend conclusions. Those are valuable skills. Until everyone in the room is doing exactly the same thing.

What looks like collaboration often becomes a competition between perspectives.

Expertise creates a subtle hierarchy of importance. People don't simply defend their perspective; they defend the importance of their perspective. Over time, collaboration becomes less about integrating viewpoints and more about persuading others that their concern deserves priority.

Each function becomes increasingly skilled at explaining why its view is right and increasingly less skilled at understanding why others see the issue differently.

The result is friction; not because people are difficult, but because they are doing exactly what they have been trained to do.

Silos Are Not a Communication Problem

Many leaders assume silos exist because people don't communicate enough.

In my experience, that's rarely the issue. People are often talking constantly. The problem is that they are talking from within their own assumptions. Two people can hear the same information and reach completely different conclusions because they are interpreting it through different professional lenses.

The scientist sees risk, the operations leader sees execution, the finance leader sees cost, the legal team sees exposure, the communications team sees stakeholder impact.

Everyone is looking at the same situation, and everyone is seeing something different. And often, everyone believes the thing they are seeing deserves priority.

Why Silos Matter More Than Ever

McKinsey research found that executives ranked siloed thinking and behaviour as the number one obstacle to building a healthy digital culture.

As organisations become more interconnected and problems become more complex, success increasingly depends on the ability of different disciplines to work together. (McKinsey & Company)

The challenge is that organisations often try to solve silos structurally. They reorganise teams, redraw reporting lines, create committees, or launch collaboration initiatives.

Sometimes these help. Often they don't. Because silos are not primarily structural. They are behavioural. And behavioural problems are rarely solved by organisational charts.

Breaking Down Silos Starts With Understanding

The solution is not to eliminate expertise. The solution is to recognise its limitations.

The most effective leaders help people understand that different perspectives are not obstacles to progress. They are the raw material from which better decisions are made.

The goal is not agreement. The goal is understanding.

Because when experts stop defending their perspective long enough to understand someone else's, something important happens. The silo doesn't disappear, but the walls become permeable. People begin to see not only what matters to them, but why it matters to others.

And that is where collaboration, innovation and better decisions begin.
